save the PIC register before a function call.
(call_value expander): Likewise.
From-SVN: r8718
* config/pa/pa.h (DO_GLOBAL_DTORS_BODY): Define. Include a
reference to __gcc_plt_call so __gcc_plt_call always appears in
executables which reference __main.
From-SVN: r8702
* pa.h (readonly_section): During PIC code generation, put
readonly data into the standard data section.
* pa.c (pic_label_operand): Disallow SYMBOL_REFs (constant data).
From-SVN: r8661
* pa.h (DEFAULT_PCC_STRUCT_RETURN): Define as zero.

with an unfilled delay slot.
(output_bb, output_dbra, output_movb): Likewise.
From-SVN: r8441

* pa.c (output_function_prologue): Keep track of the total number
of code bytes emitted for each source file.
(output_call): Handle TARGET_PORTABLE_RUNTIME and millicode calls
for TARGET_MILLICODE_LONG_CALLS. Emit an inline long-call if
needed. If emitting an inline long-call, perform argument relocations
before the call if they are needed, unfill the delay slot of the
call if necessary.
* pa.md (define_delay for millicode): Disable the delay slot if
TARGET_MILLICODE_LONG_CALLS.
(millicode insns and indirect calls): Properly compute length for
both TARGET_PORTABLE_RUNTIME and TARGET_MILLICODE_LONG_CALLS.

TARGET_MILLICODE_LONG_CALLS into account in the length
computation.
From-SVN: r8422
* pa.c (secondary_reload_class): Refine. Readonly data needs a
secondary reload only during PIC generation. Loading a floating
point register with a constant requires a register from R1_REGS
during -fPIC code generation.

during PIC code generation.
(hppa_legitimize_address): If flag_pic is nonzero, then
immediately call legitimize_pic_address.

constant data. Handle secondary reloads for PIC. Use
pic_label_operand rather than open coding the test. Handle
loading a LABEL_REF when generating PIC.
(legitimzie_pic_address): Handle constant data addressing for PIC
here. Fix loading of symbolic addresses for -fPIC generation.
(pic_label_operand): Renamed from pic_operand. Handle any read
only operand (such as constant data). Reject function addresses,

PIC code.
(finalize_pic): Don't emit code for initialization of
hppa_save_pic_table_rtx here. Don't claim we USE
pic_offset_table_rtx at function end.
* pa.h (SELECT_RTX_SECTION): Define. During PIC generation
everything (in the constant pool) goes into the data space.
(PRINT_OPERAND_ADDRESS): Handle CONST_INTs during PIC
generation. Handle LO_SUM address during -fPIC generation.
(LEGITIMATE_CONSTANT_P): Reject function labels when generating
PIC code.
(GO_IF_LEGITIMATE_ADDRESS): Only accept pic_reg + SYMBOL_REF for
-fpic.
(EXTRA_SECTION_FUNCTIONS): For -fpic, use the TEXT section for
constants to avoid GAS lossage.
(OVERRIDE_OPTIONS): Delete.
(PIC_OFFSET_TABLE_REG_CALL_CLOBBERED): Define.
(FINALIZE_PIC): Delete definition.

(HImode high and lo_sum): Only accept const_int_operands.
(pic_load_label): Force output to be in %r1.
(pic_highpart): New pattern. Output must go into %r1. More
linker trickery.

source is a symbolic operand. Handle CONST_INT LO_SUM during PIC
generation. Simplify.
(define_split for symbolic_operand load): Do not accept a symbolic
operand that is a pic_label_operand.
(pic_load_label): Name this pattern. Mask least significant bits
and optimize when a simple label is within reach of an ldo.
(call, call_value): Emit new-style USE information for
pic_offset_table_rtx. Emit code for initialization of
hppa_save_pic_table_rtx and wrap it into push_topmost_sequence()
and pop_topmost_sequence() calls.
From-SVN: r8419
(COLLECT_QUALIFY_MATCH): Define to ignore all symbols of types other
than code.
(REAL_NM_FILE_NAME): Define to "/bin/nm" to force use of the vendor nm.
From-SVN: r8316
* pa.c (emit_move_sequence): Handle secondary FP load/store
reloads of the form (subreg (mem (plus (reg) (disp)))).
(secondary_reload_class): A secondary register is needed to handle
out-of-range FP loads and stores.
* pa.md (reload_indf, reload_outdf): New expanders.
(reload_insf, reload_outsf): Likewise.
From-SVN: r8077
* pa.c (hppa_legitimize_address): Do nothing with function label
arithmetic.
(emit_move_sequence): Split up function label arithmetic so that
