libctf, include: support foreign-endianness symtabs with CTF
The CTF symbol lookup machinery added recently has one deficit: it assumes the symtab is in the machine's native endianness. This is always true when the linker is writing out symtabs (because cross linkers byteswap symbols only after libctf has been called on them), but may be untrue in the cross case when the linker or another tool (objdump, etc) is reading them. Unfortunately the easy way to model this to the caller, as an endianness field in the ctf_sect_t, is precluded because doing so would change the size of the ctf_sect_t, which would be an ABI break. So, instead, allow the endianness of the symtab to be set after open time, by calling one of the two new API functions ctf_symsect_endianness (for ctf_dict_t's) or ctf_arc_symsect_endianness (for entire ctf_archive_t's). libctf calls these functions automatically for objects opened via any of the BFD-aware mechanisms (ctf_bfdopen, ctf_bfdopen_ctfsect, ctf_fdopen, ctf_open, or ctf_arc_open), but the various mechanisms that just take raw ctf_sect_t's will assume the symtab is in native endianness and need a later call to ctf_*symsect_endianness to adjust it if needed. (This call is basically free if the endianness is actually native: it only costs anything if the symtab endianness was previously guessed wrong, and there is a symtab, and we are using it directly rather than using symtab indexing.) Obviously, calling ctf_lookup_by_symbol or ctf_symbol_next before the symtab endianness is correctly set will probably give wrong answers -- but you can set it at any time as long as it is before then. include/ChangeLog 2020-11-23 Nick Alcock <nick.alcock@oracle.com> * ctf-api.h: Style nit: remove () on function names in comments.

libctf, include: add ctf_getsymsect and ctf_getstrsect
libctf has long provided ctf_getdatasect, which hands back a pointer to the CTF section a (read-only) dict came from. But it has no such functions to return pointers to the ELF symbol table or string table it's working from, which is unfortunate because several libctf functions (ctf_open, ctf_fdopen, and ctf_bfdopen) figure out which string and symbol table to use themselves, and don't tell the user what they decided, so the caller can't agree on which symtab to use with libctf even if it wanted to. Add a pair of functions to return the symtab and strtab in use. Like ctf_getdatasect, these return ctf_sect_t structures by value, filled with all-NULL/0 content if a symtab or strtab is not being used. include/ChangeLog 2020-11-20 Nick Alcock <nick.alcock@oracle.com> * ctf-api.h (ctf_getsymsect): New.

libctf, include: CTF-archive-wide symbol lookup
CTF archives may contain multiple dicts, each of which contain many types and possibly a bunch of symtypetab entries relating to those types: each symtypetab entry is going to appear in exactly one dict, with the corresponding entries in the other dicts empty (either pads, or indexed symtypetabs that do not mention that symbol). But users of libctf usually want to get back the type associated with a symbol without having to dig around to find out which dict that type might be in. This adds machinery to do that -- and since you probably want to do it repeatedly, it adds internal caching to the ctf-archive machinery so that iteration over archives via ctf_archive_next and repeated symbol lookups do not have to repeatedly reopen the archive. (Iteration using ctf_archive_iter will gain caching soon.) Two new API functions: ctf_dict_t * ctf_arc_lookup_symbol (ctf_archive_t *arc, unsigned long symidx, ctf_id_t *typep, int *errp); This looks up the symbol with index SYMIDX in the archive ARC, returning the dictionary in which it resides and optionally the type index as well. Errors are returned in ERRP. The dict should be ctf_dict_close()d when done, but is also cached inside the ctf_archive so that the open cost is only paid once. The result of the symbol lookup is also cached internally, so repeated lookups of the same symbol are nearly free. void ctf_arc_flush_caches (ctf_archive_t *arc); Flush all the caches. Done at close time, but also available as an API function if users want to do it by hand. include/ChangeLog 2020-11-20 Nick Alcock <nick.alcock@oracle.com> * ctf-api.h (ctf_arc_lookup_symbol): New.

libctf: symbol type linking support
This adds facilities to write out the function info and data object
sections, which efficiently map from entries in the symbol table to
types. The write-side code is entirely new: the read-side code was
merely significantly changed and support for indexed tables added
(pointed to by the no-longer-unused cth_objtidxoff and cth_funcidxoff
header fields).
With this in place, you can use ctf_lookup_by_symbol to look up the
types of symbols of function and object type (and, as before, you can
use ctf_lookup_variable to look up types of file-scope variables not
present in the symbol table, as long as you know their name: but
variables that are also data objects are now found in the data object
section instead.)
(Compatible) file format change:
The CTF spec has always said that the function info section looks much
like the CTF_K_FUNCTIONs in the type section: an info word (including an
argument count) followed by a return type and N argument types. This
format is suboptimal: it means function symbols cannot be deduplicated
and it causes a lot of ugly code duplication in libctf. But
conveniently the compiler has never emitted this! Because it has always
emitted a rather different format that libctf has never accepted, we can
be sure that there are no instances of this function info section in the
wild, and can freely change its format without compatibility concerns or
a file format version bump. (And since it has never been emitted in any
code that generated any older file format version, either, we need keep
no code to read the format as specified at all!)
So the function info section is now specified as an array of uint32_t,
exactly like the object data section: each entry is a type ID in the
type section which must be of kind CTF_K_FUNCTION, the prototype of
this function.
This allows function types to be deduplicated and also correctly encodes
the fact that all functions declared in C really are types available to
the program: so they should be stored in the type section like all other
types. (In format v4, we will be able to represent the types of static
functions as well, but that really does require a file format change.)
We introduce a new header flag, CTF_F_NEWFUNCINFO, which is set if the
new function info format is in use. A sufficiently new compiler will
always set this flag. New libctf will always set this flag: old libctf
will refuse to open any CTF dicts that have this flag set. If the flag
is not set on a dict being read in, new libctf will disregard the
function info section. Format v4 will remove this flag (or, rather, the
flag has no meaning there and the bit position may be recycled for some
other purpose).
New API:
Symbol addition:
ctf_add_func_sym: Add a symbol with a given name and type. The
type must be of kind CTF_K_FUNCTION (a function
pointer). Internally this adds a name -> type
mapping to the ctf_funchash in the ctf_dict.
ctf_add_objt_sym: Add a symbol with a given name and type. The type
kind can be anything, including function pointers.
This adds to ctf_objthash.
These both treat symbols as name -> type mappings: the linker associates
symbol names with symbol indexes via the ctf_link_shuffle_syms callback,
which sets up the ctf_dynsyms/ctf_dynsymidx/ctf_dynsymmax fields in the
ctf_dict. Repeated relinks can add more symbols.
Variables that are also exposed as symbols are removed from the variable
section at serialization time.
CTF symbol type sections which have enough pads, defined by
CTF_INDEX_PAD_THRESHOLD (whether because they are in dicts with symbols
where most types are unknown, or in archive where most types are defined
in some child or parent dict, not in this specific dict) are sorted by
name rather than symidx and accompanied by an index which associates
each symbol type entry with a name: the existing ctf_lookup_by_symbol
will map symbol indexes to symbol names and look the names up in the
index automatically. (This is currently ELF-symbol-table-dependent, but
there is almost nothing specific to ELF in here and we can add support
for other symbol table formats easily).
The compiler also uses index sections to communicate the contents of
object file symbol tables without relying on any specific ordering of
symbols: it doesn't need to sort them, and libctf will detect an
unsorted index section via the absence of the new CTF_F_IDXSORTED header
flag, and sort it if needed.
Iteration:
ctf_symbol_next: Iterator which returns the types and names of symbols
one by one, either for function or data symbols.
This does not require any sorting: the ctf_link machinery uses it to
pull in all the compiler-provided symbols cheaply, but it is not
restricted to that use.
(Compatible) changes in API:
ctf_lookup_by_symbol: can now be called for object and function
symbols: never returns ECTF_NOTDATA (which is
now not thrown by anything, but is kept for
compatibility and because it is a plausible
error that we might start throwing again at some
later date).
Internally we also have changes to the ctf-string functionality so that
"external" strings (those where we track a string -> offset mapping, but
only write out an offset) can be consulted via the usual means
(ctf_strptr) before the strtab is written out. This is important
because ctf_link_add_linker_symbol can now be handed symbols named via
strtab offsets, and ctf_link_shuffle_syms must figure out their actual
names by looking in the external symtab we have just been fed by the
ctf_link_add_strtab callback, long before that strtab is written out.

bfd, include, ld, binutils, libctf: CTF should use the dynstr/sym
This is embarrassing. The whole point of CTF is that it remains intact even after a binary is stripped, providing a compact mapping from symbols to types for everything in the externally-visible interface of an ELF object: it has connections to the symbol table for that purpose, and to the string table to avoid duplicating symbol names. So it's a shame that the hooks I implemented last year served to hook it up to the .symtab and .strtab, which obviously disappear on strip, leaving any accompanying the CTF dict containing references to strings (and, soon, symbols) which don't exist any more because their containing strtab has been vaporized. The original Solaris design used .dynsym and .dynstr (well, actually, .ldynsym, which has more symbols) which do not disappear. So should we. Thankfully the work we did before serves as guide rails, and adjusting things to use the .dynstr and .dynsym was fast and easy. The only annoyance is that the dynsym is assembled inside elflink.c in a fairly piecemeal fashion, so that the easiest way to get the symbols out was to hook in before every call to swap_symbol_out (we also leave in a hook in front of symbol additions to the .symtab because it seems plausible that we might want to hook them in future too: for now that hook is unused). We adjust things so that rather than being offered a whole hash table of symbols at once, libctf is now given symbols one at a time, with st_name indexes already resolved and pointing at their final .dynstr offsets: it's now up to libctf to resolve these to names as needed using the strtab info we pass it separately. Some bits might be contentious. The ctf_new_dynstr callback takes an elf_internal_sym, and this remains an elf_internal_sym right down through the generic emulation layers into ldelfgen. This is no worse than the elf_sym_strtab we used to pass down, but in the future when we gain non-ELF CTF symtab support we might want to lower the elf_internal_sym to some other representation (perhaps a ctf_link_symbol) in bfd or in ldlang_ctf_new_dynsym. We rename the 'apply_strsym' hooks to 'acquire_strings' instead, becuse they no longer have anything to do with symbols. There are some API changes to pieces of API which are technically public but actually totally unused by anything and/or unused by anything but ld so they can change freely: the ctf_link_symbol gains new fields to allow symbol names to be given as strtab offsets as well as strings, and a symidx so that the symbol index can be passed in. ctf_link_shuffle_syms loses its callback parameter: the idea now is that linkers call the new ctf_link_add_linker_symbol for every symbol in .dynsym, feed in all the strtab entries with ctf_link_add_strtab, and then a call to ctf_link_shuffle_syms will apply both and arrange to use them to reorder the CTF symtab at CTF serialization time (which is coming in the next commit). Inside libctf we have a new preamble flag CTF_F_DYNSTR which is always set in v3-format CTF dicts from this commit forwards: CTF dicts without this flag are associated with .strtab like they used to be, so that old dicts' external strings don't turn to garbage when loaded by new libctf. Dicts with this flag are associated with .dynstr and .dynsym instead. (The flag is not the next in sequence because this commit was written quite late: the missing flags will be filled in by the next commit.)

libctf, include, binutils, gdb: rename CTF-opening functions
The functions that return ctf_dict_t's given a ctf_archive_t and a name are very clumsily named. It sounds like they return *archives*, not dictionaries, and the names are very long and clunky. Why do we have a ctf_arc_open_by_name when it opens a dictionary, not an archive, and when there is no way to open a dictionary in any other way? The answer is purely internal: the function is located in ctf-archive.c, and everything in there was called ctf_arc_*, and there is another way to open a dict (by offset in the archive), that is internal to ctf-archive.c and that nothing else can call. This is clearly bad naming. The internal organization of the source tree should not dictate public API names! So rename things (keeping the old, bad names for compatibility), and adjust all users. You now open a dict using ctf_dict_open, and open it giving ELF sections via ctf_dict_open_sections. binutils/ChangeLog 2020-11-20 Nick Alcock <nick.alcock@oracle.com> * objdump.c (dump_ctf): Use ctf_dict_open, not ctf_arc_open_by_name. * readelf.c (dump_section_as_ctf): Likewise. gdb/ChangeLog 2020-11-20 Nick Alcock <nick.alcock@oracle.com> * ctfread.c (elfctf_build_psymtabs): Use ctf_dict_open, not ctf_arc_open_by_name. include/ChangeLog 2020-11-20 Nick Alcock <nick.alcock@oracle.com> * ctf-api.h (ctf_arc_open_by_name): Rename to...

libctf, include, binutils, gdb, ld: rename ctf_file_t to ctf_dict_t
The naming of the ctf_file_t type in libctf is a historical curiosity. Back in the Solaris days, CTF dictionaries were originally generated as a separate file and then (sometimes) merged into objects: hence the datatype was named ctf_file_t, and known as a "CTF file". Nowadays, raw CTF is essentially never written to a file on its own, and the datatype changed name to a "CTF dictionary" years ago. So the term "CTF file" refers to something that is never a file! This is at best confusing. The type has also historically been known as a 'CTF container", which is even more confusing now that we have CTF archives which are *also* a sort of container (they contain CTF dictionaries), but which are never referred to as containers in the source code. So fix this by completing the renaming, renaming ctf_file_t to ctf_dict_t throughout, and renaming those few functions that refer to CTF files by name (keeping compatibility aliases) to refer to dicts instead. Old users who still refer to ctf_file_t will see (harmless) pointer-compatibility warnings at compile time, but the ABI is unchanged (since C doesn't mangle names, and ctf_file_t was always an opaque type) and things will still compile fine as long as -Werror is not specified. All references to CTF containers and CTF files in the source code are fixed to refer to CTF dicts instead. Further (smaller) renamings of annoyingly-named functions to come, as part of the process of souping up queries across whole archives at once (needed for the function info and data object sections). binutils/ChangeLog 2020-11-20 Nick Alcock <nick.alcock@oracle.com> * objdump.c (dump_ctf_errs): Rename ctf_file_t to ctf_dict_t.

Support SHF_GNU_RETAIN ELF section flag
The SHF_GNU_RETAIN section flag is an extension to the GNU ELF OSABI. It is defined as follows: ========================================================= Section Attribute Flags +-------------------------------------+ | Name | Value | +-------------------------------------+ | SHF_GNU_RETAIN | 0x200000 (1 << 21) | +-------------------------------------+ SHF_GNU_RETAIN The link editor should not garbage collect the section. ========================================================= The .section directive accepts the "R" flag, which indicates SHF_GNU_RETAIN should be applied to the section. There is not a direct mapping of SHF_GNU_RETAIN to the BFD section flag SEC_KEEP. Keeping these flags distinct allows SHF_GNU_RETAIN sections to be explicitly removed by placing them in /DISCARD/. bfd/ChangeLog: * elf-bfd.h (enum elf_gnu_osabi): Add elf_gnu_osabi_retain.

aarch64: Update feature RAS system registers
This patch: + updates RAS feature system registers with new RAS 1.1 regs. + extends RAS/RAS 1.1 support for all architecture levels of Armv8-A. Please note that early Armv8-A architectures do not officially support RAS extension. Rationale of the patch: To ease development so that user-friendly RAS system registers operands can be used. Certain use cases require developers to enable only more generic architecture (e.g. -march=armv8-a) during system development. Users must use RAS extension registers bearing in mind that system they use must support it. The RAS (Reliability, Availability, Serviceability) extension is a system-level extension that defines a number of system registers. RAS 1.1 (FEAT_RASv1p1) introduces five new system registers: ERXPFGCTL_EL1, ERXPFGCDN_EL1, ERXMISC2_EL1, ERXMISC3_EL1 and ERXPFGF_EL1. For details see [0].

aarch64: Add CSR PDEC instruction
This patch adds: + New feature +csre to -march command line. + New instruction CSR PDEC associated with CSRE feature. Please note that CSRE system registers were already upstreamed. This patch should finalize CSRE feature implementation. CSRE feature adds CSR PDEC (Decrements Call stack pointer by the size of a Call stack record) instruction. Although this instruction has operand (PDEC) it's instruction's only operand. PDEC forces instruction field Rt to be set to 0b1111. This results in fixed opcode of the instruction. gas/ChangeLog: 2020-10-27 Przemyslaw Wirkus <przemyslaw.wirkus@arm.com> * NEWS: Update docs. * config/tc-aarch64.c (parse_csr_operand): New operand parser.

aarch64: Add DSB instruction Armv8.7-a variant
This patch adds new variant (nXS) of DSB memory barrier instruction available in Armv8.7-a. New nXS variant has different encoding in comparison with pre Armv8.7-a DSB memory barrier variant thus new instruction and new operand was added. DSB memory nXS barrier variant specifies the limitation on the barrier operation. Allowed values are: DSB SYnXS|#28 DSB ISHnXS|#24 DSB NSHnXS|#20 DSB OSHnXS|#16 Please note that till now, for barriers, barrier operation was encoded in 4-bit unsigned immediate CRm field (in the range 0 to 15). For DSB memory nXS barrier variant, barrier operation is a 5-bit unsigned assembly instruction immediate, encoded in instruction in two bits CRm<3:2>: CRm<3:2> #imm 00 16 01 20 10 24 11 28 This patch extends current AArch64 barrier instructions with above mapping. Notable patch changes include: + New DSB memory barrier variant encoding for Armv8.7-a. + New operand BARRIER_DSB_NXS for above instruction in order to distinguish between existing and new DSB instruction flavour. + New set of DSB nXS barrier options. + New instruction inserter and extractor map between instruction immediate 5-bit value and 2-bit CRm field of the instruction itself (see FLD_CRm_dsb_nxs). + Regeneration of aarch64-[asm|dis|opc]-2.c files. + Test cases to cover new instruction assembling and disassembling. For more details regarding DSB memory barrier instruction and its Armv8.7-a flavour please refer to Arm A64 Instruction set documentation for Armv8-A architecture profile, see document pages 132-133 of [0].

RISC-V: Support GNU indirect functions.
Generally, glibc dynamic linker should have two ways to deal with ifunc - one is to handle the IRELATIVE relocations for the non-preemtive ifunc symbols, the other is to handle the R_RISCV_32/64 and R_RISCV_JUMP_SLOT relocations with the STT_IFUNC preemtive symbols. No matter which method is used, both of them should get the resolved ifunc symbols at runtime. Therefore, linker needs to generate the correct dynamic relocations for ifunc to make sure the the dynamic linker works well. For now, there are thirteen relocations are supported for ifunc in GNU ld, * R_RISCV_CALL and R_RISCV_CALL_PLT: The RISC-V compiler won't generate R_RISCV_JAL directly to jump to an ifunc. Besides, we disable the relaxations for the relocation referenced to ifunc, so just handling the R_RISCV_CALL and R_RISCV_CALL_PLT should be enough. Linker should generate a .plt entry and a .got.plt entry for it, and also needs to insert a dynamic IRELATIVE in the .got.plt enrty, or insert a R_RISCV_JUMP_SLOT when generating shared library. * R_RISCV_PCREL_HI20 and R_RISCV_PCREL_LO12_I/S: LA/LLA pattern with local fPIC ifunc symbol, or any non-PIC ifunc symbol. The PC-relative relocation. The current linker will deal with them in the same way as R_RISCV_CALL_PLT. * R_RISCV_GOT_HI20 and R_RISCV_PCREL_LO12_I/S: LA pattern with global PIC ifunc symbol. Linker should insert a dynamic IRELATIVE in the .got entry, or insert a R_RISCV_32/64 when generating shared library. * R_RISCV_32 and R_RISCV_64: Store the ifunc symbol into the data section. Linker should insert a dynamic IRELATIVE in the data section, or insert a R_RISCV_32/64 when generating shared library. * R_RISCV_HI20 and R_RISCV_LO12_I/S: The LUI + ADDI/LW/SW patterns. The absolute access relocation. The medlow model without the -fPIC compiler option should generate them. The ld ifunc testsuites "Build pr23169a" and "Build pr23169d" need the relocations, they are in the ld/testsuite/ld-ifunc/, and need compiler support. However, we also made some optimizations with reference to x86, * If GOT and PLT relocations refer to the same ifunc symbol when generating pie, then they can actually share a .got entry without creating two entries to store the same value and relocation. * If GOT, PLT and DATA relocations refer to the same ifunc symbol when generating position dependency executable, then linker will fill the address of .plt entry into the corresponding .got entry and data section, without insert any dynamic relocations for the GOT and DATA relocations. For the ifunc testcases, there are three types of them, 1. ifunc-reloc-*: Only check the single type of relocation refers to ifunc symbol. * ifunc-reloc-call: R_RISCV_CALL and R_RISCV_CALL_PLT. * ifunc-reloc-data: R_RISCV_32 and R_RISCV_64. * ifunc-reloc-got: R_RISCV_GOT_HI20 and R_RISCV_PCREL_LO_I/S. * ifunc-reloc-pcrel: R_RISCV_PCREL_HI20 and R_RISCV_PCREL_LO_I/S. 2. ifunc-[nonplt|plt]-*: If we don't have PLT relocs, then don't need to create the PLT and it's .plt entries. * ifunc-nonplt: Combine R_RISCV_GOT_HI20 and R_RISCV_32/64. * ifunc-plt: Combine all ifunc relocations. 3. ifunc-seperate-*: If we link the ifunc caller and resolver into the same module (link the objects), then the results are the same as the ifunc-reloc-* and ifunc-[noplt|plt]-* testcases. Consider the cases that the ifunc callers and resolver are in the different modules, that is, we compile the ifunc resolver to the shared library first, and then link it with the ifunc callers. The output of ifunc callers should be the same as the normal STT_FUNC cases, and the shared ifunc resolver should define the symbols as STT_IFUNC. The R_RISCV_PCREL_HI20 reloc is special. It should be linked and resolved locally, so if the ifunc resolver is defined in other modules (other shared libraries), then the R_RISCV_PCREL_HI20 is unresolvable, and linker should issue an unresolvable reloc error. bfd/ * elfnn-riscv.c: Include "objalloc.h" since we need objalloc_alloc. (riscv_elf_link_hash_table): Add loc_hash_table and loc_hash_memory for local STT_GNU_IFUNC symbols. (riscv_elf_got_plt_val): Removed. (riscv_elf_local_htab_hash, riscv_elf_local_htab_eq): New functions. Use to compare local hash entries. (riscv_elf_get_local_sym_hash): New function.

(riscv_elf_link_hash_table_create): Create hash table for local ifunc. (riscv_elf_check_relocs): Create a fake global symbol to track the local ifunc symbol. Add support to check and handle the relocations reference to ifunc symbols. (allocate_dynrelocs): Let allocate_ifunc_dynrelocs and allocate_local_ifunc_dynrelocs to handle the ifunc symbols if they are defined and referenced in a non-shared object. (allocate_ifunc_dynrelocs): New function. Allocate space in .plt, .got and associated reloc sections for ifunc dynamic relocs.

elf: Add -z unique-symbol to avoid duplicated local symbol names
The symbol string table in the .symtab section is optional and cosmetic.
The contents of the .symtab section have no impact on run-time execution.
The symbol names in the symbol string table help distinguish addresses at
different locations. Add a linker option, -z unique-symbol, to avoid
duplicated local symbol names in the symbol string table.
This feature was well received by the livepatch maintainers. It not only
solves the duplicated local symbol name problem, but also would allow
livepatch to more precisely locate duplicate symbols in general for
patching.

MSP430: Support relocations for subtract expressions in .uleb128 directives
Link-time relaxations of branches are common for MSP430, given that GCC
can generate pessimal branch instructions, and the
-mcode-region=either/-mdata-region=either options to shuffle sections
can further change the type of branch instruction required.
These relaxations can result in invalid code when .uleb128
directives, used in the .gcc_except_table section, are used to calculate
the distance between two labels. A value for the .uleb128 directive is
calculated at assembly-time, and can't be updated at link-time, even if
relaxation causes the distance between the labels to change.
This patch adds relocations for subtract expressions in .uleb128
directives, to allow the linker to re-calculate the value of these
expressions after relaxation has been performed.

aarch64: Add base support for Armv8-R
This patch adds the basic infrastructure needed to support Armv8-R in AArch64 binutils: new command-line flags, new feature bits, a new BFD architecture, and support for differentiating between architecture variants in the disassembler. The new command-line options added by this patch are -march=armv8-r in GAS and -m aarch64:armv8-r in objdump. The disassembler support is necessary since Armv8-R AArch64 introduces a system register (VSCTLR_EL2) which shares an encoding with a different system register (TTBR0_EL2) in Armv8-A. This also allows us to use the correct preferred disassembly for the new DFB alias introduced in Armv8-R. bfd/ChangeLog: 2020-09-08 Alex Coplan <alex.coplan@arm.com> * archures.c (bfd_mach_aarch64_8R): New. * bfd-in2.h: Regenerate. * cpu-aarch64.c (bfd_aarch64_arch_v8_r): New.

libctf, binutils, include, ld: gettextize and improve error handling
This commit follows on from the earlier commit "libctf, ld, binutils: add textual error/warning reporting for libctf" and converts every error in libctf that was reported using ctf_dprintf to use ctf_err_warn instead, gettextizing them in the process, using N_() where necessary to avoid doing gettext calls unless an error message is actually generated, and rephrasing some error messages for ease of translation. This requires a slight change in the ctf_errwarning_next API: this API is public but has not been in a release yet, so can still change freely. The problem is that many errors are emitted at open time (whether opening of a CTF dict, or opening of a CTF archive): the former of these throws away its incompletely-initialized ctf_file_t rather than return it, and the latter has no ctf_file_t at all. So errors and warnings emitted at open time cannot be stored in the ctf_file_t, and have to go elsewhere. We put them in a static local in ctf-subr.c (which is not very thread-safe: a later commit will improve things here): ctf_err_warn with a NULL fp adds to this list, and the public interface ctf_errwarning_next with a NULL fp retrieves from it. We need a slight exception from the usual iterator rules in this case: with a NULL fp, there is nowhere to store the ECTF_NEXT_END "error" which signifies the end of iteration, so we add a new err parameter to ctf_errwarning_next which is used to report such iteration-related errors. (If an fp is provided -- i.e., if not reporting open errors -- this is optional, but even if it's optional it's still an API change. This is actually useful from a usability POV as well, since ctf_errwarning_next is usually called when there's been an error, so overwriting the error code with ECTF_NEXT_END is not very helpful! So, unusually, ctf_errwarning_next now uses the passed fp for its error code *only* if no errp pointer is passed in, and leaves it untouched otherwise.) ld, objdump and readelf are adapted to call ctf_errwarning_next with a NULL fp to report open errors where appropriate. The ctf_err_warn API also has to change, gaining a new error-number parameter which is used to add the error message corresponding to that error number into the debug stream when LIBCTF_DEBUG is enabled: changing this API is easy at this point since we are already touching all existing calls to gettextize them. We need this because the debug stream should contain the errno's message, but the error reported in the error/warning stream should *not*, because the caller will probably report it themselves at failure time regardless, and reporting it in every error message that leads up to it leads to a ridiculous chattering on failure, which is likely to end up as ridiculous chattering on stderr (trimmed a bit): CTF error: `ld/testsuite/ld-ctf/A.c (0): lookup failure for type 3: flags 1: The parent CTF dictionary is unavailable' CTF error: `ld/testsuite/ld-ctf/A.c (0): struct/union member type hashing error during type hashing for type 80000001, kind 6: The parent CTF dictionary is unavailable' CTF error: `deduplicating link variable emission failed for ld/testsuite/ld-ctf/A.c: The parent CTF dictionary is unavailable' ld/.libs/lt-ld-new: warning: CTF linking failed; output will have no CTF section: `The parent CTF dictionary is unavailable' We only need to be told that the parent CTF dictionary is unavailable *once*, not over and over again! errmsgs are still emitted on warning generation, because warnings do not usually lead to a failure propagated up to the caller and reported there. Debug-stream messages are not translated.

libctf, link: tie in the deduplicating linker
This fairly intricate commit connects up the CTF linker machinery (which operates in terms of ctf_archive_t's on ctf_link_inputs -> ctf_link_outputs) to the deduplicator (which operates in terms of arrays of ctf_file_t's, all the archives exploded). The nondeduplicating linker is retained, but is not called unless the CTF_LINK_NONDEDUP flag is passed in (which ld never does), or the environment variable LD_NO_CTF_DEDUP is set. Eventually, once we have confidence in the much-more-complex deduplicating linker, I hope the nondeduplicating linker can be removed. In brief, what this does is traverses each input archive in ctf_link_inputs, opening every member (if not already open) and tying child dicts to their parents, shoving them into an array and constructing a corresponding parents array that tells the deduplicator which dict is the parent of which child. We then call ctf_dedup and ctf_dedup_emit with that array of inputs, taking the outputs that result and putting them into ctf_link_outputs where the rest of the CTF linker expects to find them, then linking in the variables just as is done by the nondeduplicating linker. It also implements much of the CU-mapping side of things. The problem CU-mapping introduces is that if you map many input CUs into one output, this is saying that you want many translation units to produce at most one child dict if conflicting types are found in any of them. This means you can suddenly have multiple distinct types with the same name in the same dict, which libctf cannot really represent because it's not something you can do with C translation units. The deduplicator machinery already committed does as best it can with these, hiding types with conflicting names rather than making child dicts out of them: but we still need to call it. This is done similarly to the main link, taking the inputs (one CU output at a time), deduplicating them, taking the output and making it an input to the final link. Two (significant) optimizations are done: we share atoms tables between all these links and the final link (so e.g. all type hash values are shared, all decorated type names, etc); and any CU-mapped links with only one input (and no child dicts) doesn't need to do anything other than renaming the CU: the CU-mapped link phase can be skipped for it. Put together, large CU-mapped links can save 50% of their memory usage and about as much time (and the memory usage for CU-mapped links is significant, because all those output CUs have to have all their types stored in memory all at once). include/ * ctf-api.h (CTF_LINK_NONDEDUP): New, turn off the deduplicator. libctf/ * ctf-impl.h (ctf_list_splice): New. * ctf-util.h (ctf_list_splice): Likewise. * ctf-link.c (link_sort_inputs_cb_arg_t): Likewise.
