scheduling. Handle anti-dependendy cases involving fp division
and sqrt. Handle output dependencies correctly. Break TYPE_FPMUL
into TYPE_FPMULSGL and TYPE_FPMULDBL.

* 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.
(RETURN_IN_MEMORY): Only large structs (>8 bytes) and addressable
structs should be returned in memory.

TARGET_PORTABLE_RUNTIME.
(TARGET_MILLICODE_LONG_CALLS): New target flag.
* 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.

than 240000 bytes of code have already been output. Take
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.
(read_only_operand): Constant pool entries are no longer read only
during PIC code generation.
(hppa_legitimize_address): If flag_pic is nonzero, then
immediately call legitimize_pic_address.
(emit_move_sequence): Call legitimize_pic_address to handle
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,
Accept SYMBOL_REF with the read-only bit set. Generalize to
handle (const (plus (reg) (int))).
(finalize_pic): Delete unused function.
(check_pic): Delete function.
(pic_pc_rtx): Delete variable definition.
(current_function_uses_pic_offset_table): Delete extern decl.

(output_global_address): Don't tack on "-$global$" when generating
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.
(INIT_EXPANDERS): Define. Clear hppa_save_pic_table_rtx here.
* pa.md: Use !flag_pic rather than calling check_pic.
(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.
(symbolic high and lo_sum): Disallow during PIC generation if
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.

and NON_SHIFT_REGS.
(REG_CLASS_NAMES): Likewise.
(REG_CLASS_CONTENTS): Likewise.
(REGNO_REG_CLASS): Likewise.
(HARD_REGNO_MODE_OK): Corresponding changes. Don't force 1.0 fpregs
