(optimize_reg_copy_1): Tighten up code to properly handle the case
when SRC or DEST is a multi-word hard register and only some parts of
the register are set or used. Also, avoid updating register status
for DEST if we can't do the optimization.

* pa.md (fp_alu function unit, case fpcc): Fpcc instructions use
the fpalu unit. In the most common case their result will be used
in a ftest instruction. Minimum distance between the fcmp and
ftest instruction is 4.
From-SVN: r2370
(dwarfout_init, dwarfout_finish): Don't output labels
or .debug_aranges entries for .data1 and .rodata1 as these
sections aren't currently used.
From-SVN: r2369
(mark_target_live_regs): Look at USE insns made by update_block when scanning
forward past target.
(mark_target_live_regs, dbr_schedule): Use GET_RTX_CLASS.
From-SVN: r2366
(body_{begin,end}_attribute): New functions.
(dwarf_attr_name): Print AT_body_begin and AT_body_end.
(output_{local,global}_subroutine_die): Output the new attributes.
From-SVN: r2361
(CONSTANT_ALIGNMENT, DATA_ALIGNMENT): Base on FASTEST_ALIGNMENT.
(READONLY_DATA_SECTION): Don't override svr4.h
(ASM_OUTPUT_CASE_LABEL): For svr4, use .rodata.

(best_from_align): Add a target processor dimension for
-m88000, -m88110, and -m88100.
(expand_block_move): Choose method and limits based on -m88xxx option.
(block_move_no_loop): Extend to allow DImode.
(output_call): Use different syntax for GAS.

In the first part (instead of va-*.h), define
__gnuc_va_list, as in gstdarg.h. Always use __gunc_va_list
as basis for defining va_list.
Move interaction with BSD-NET2 down to where va_list itself is defined.
From-SVN: r2336
(NO_DOLLAR_IN_LABEL): Undef because gas understands dollars
in labels and gdb expects them if configured for gas.
(STARTFILE_SPEC): Include huge.o to be compatible with native cc.
(ASM_OUTPUT_CONSTRUCTOR, ASM_OUTPUT_DESTRUCTOR):
(CTOR_LISTS_DEFINED_EXTERNALLY, DO_GLOBAL_DTORS_BODY):
(STARTFILE_SPEC): Conditionally redefine for a collectless version
of gcc if USE_COLLECT2 is not defined.
From-SVN: r2335
(rescan): If traditional, recognize # only at bol.
(main) [VMS]: Use .obj, not .o, in dependencies output.
(do_include): Delete unreachable goto after '"' case.
(do_xifdef): Skip all kinds of whitespace, in bof test.
