* pa.h (ASM_OUTPUT_EXTERNAL): Don't let assemble_name clobber
the value of TREE_SYMBOL_REFERENCED.
* pa-ghpux9.h (LINK_SPEC): Pass "-z" to the linker to enable
trap on null pointer dereference for programs built on hpux9.
* pa-hpux9.h, pa1-ghpux9.h, pa1-hpux9.h: Likewise.
* pa.c (output_function_prologue): No longer need to keep
track of the total number code bytes when TARGET_GAS &&
not TARGET_PORTABLE_RUNTIME.
* pa.h (DBX_OUTPUT_MAIN_SOURCE_FILE_END): Use .NSUBSPA when
not TARGET_PORTABLE_RUNTIME.
(ASM_OUTPUT_FUNCTION_PREFIX): Define. Prefix functions with
.NSUBSPA when TARGET_GAS and not TARGET_PORTABLE_RUNTIME.
* pa.md (symbolic high patterns): Use 'H' to print the symbolic
address so that the constant part gets rounded.
* pa.c (print_operand): Handle 'H' operand for high part of a
symbolic address with a rounded constant.
(output_global_address): New argument "rounded_constant". All
callers changed appropriately.
* x-pa-hpux (FIXPROTO_DEFINES): Add -D_HPUX_SOURCE.
* pa.h (CPP_SPEC): Only pass -D_HPUX_SOURCE and -D_HIUX_SOURCE if
-ansi is not present.
(CPP_PREDEFINES): Remove -D_HPUX_SOURCE and/or -D_HIUX_SOURCE.
* pa-ghiux.h (CPP_PREDEFINES): Likewise.
* pa-gux7.h (CPP_PREDEFINES): Likewise.
* pa-hiux.h (CPP_PREDEFINES): Likewise.
* pa-hpux.h (CPP_PREDEFINES): Likewise.
* pa-hpux7.h (CPP_PREDEFINES): Likewise.
* pa1-ghiux.h (CPP_PREDEFINES): Likewise.
* pa1-hiux.h (CPP_PREDEFINES): Likewise.
* pa-hpux.h (LINK_SPEC): If -mlinker-opt, then pass -O to the
linker.
* pa-ghpux.h, pa-hpux9.h, pa-ghpux9.h: Likewise.
* pa1-ghpux9.h, pa1-hpux9.h: Likewise.
* pa.h (LINK_SPEC): Likewise.
(TARGET_SWITCHES): Add -mlinker-opt.
* pa.md (all peepholes): Disable if TARGET_SOFT_FLOAT.
* pa.c (pa_reorg): If TARGET_GAS, then emit insns to mark
the beginning and end of the branch table.
* pa.md (begin_brtab): New insn. Just a marker so GCC knows
where to put the .begin_brtab pseudo-op.
(end_brtab): Similarly.
* pa.h (EXTRA_SECTIONS): Add in_ctors and in_dtors if
CTORS_SECTION_FUNCTION is defined. Else define dummy
versions of CTORS_SECTION_FUNCTION and DTORS_SECTION_FUNCTION.
(EXTRA_SECTION_FUNCTIONS): Add CTORS_SECTION_FUNCTION and
DTORS_SECTION_FUNCTION.
* pa.md: Add peepholes to improve spill code generated
by reload when we run out of FP registers.
