6318 * i386/bsd.h (ASM_FILE_START): Don't use dump_base_name, it is
6319 wrong and should only be used for dump related things, not
6320 debugging information, instead main_input_filename should be used.
6321 Also, reuse output_file_directive if possible.

6361 identifier character. Take no arguments.
6362 (cpp_reader_init): Call initialize_char_syntax with no

6406 hardcoded MASK, which is safe since this is the source
6409 * cppexp.c: Bring over changes to cpp_parse_escape from cccp.c
6410 to handle wide character constants in #if directives. The
6411 function now returns a HOST_WIDE_INT, and takes a third
6412 argument which is a binary mask for all legal values (0x00ff
6413 for 8-bit `char', 0xffff for 16-bit `wchar_t', etc.) Define
6414 MAX_CHAR_TYPE_MASK and MAX_WCHAR_TYPE_MASK. Change callers of
6415 cpp_parse_escape to match. [Fixes c-torture/execute/widechar-1.c]

7108 the wrong times. Until a VMSie can look at this, it's better

7220 The strategy we now use is to pre allocate the top_elt along
7221 with the EH context so that each thread has its own top_elt.
7222 This is necessary as the dynamic cleanup chain is used on the
7223 top element of the stack and each thread MUST have its own.

13319 Rewrite Sparc backend for better code generation and
13320 improved sparc64 support.
13321 * config/sparc/sp64-elf.h: Set JUMP_TABLES_IN_TEXT_SECTION to
13323 * config/sparc/sysv4.h: Likewise.
13324 * config/sparc/sparc.c (v8plus_regcmp_p, sparc_operand,
13325 move_operand, v8plus_regcmp_op, emit_move_sequence,

13327 output_move_double, output_move_quad, output_fp_move_double,
13328 move_quad_direction, output_fp_move_quad, output_scc_insn):
13330 (small_int_or_double): New predicate.
13331 (gen_compare_reg): Remove TARGET_V8PLUS cmpdi_v8plus emission.
13332 (legitimize_pic_address): Emit movsi_{high,lo_sum}_pic instead of
13333 old pic_{sethi,lo_sum}_si patterns.
13334 (mem_min_alignment): New generic function to replace
13335 mem_aligned_8, which uses REGNO_POINTER_ALIGN information when
13336 available and can test for arbitrary alignments. All callers
13338 (save_regs, restore_regs, build_big_number,
13339 output_function_prologue, output_cbranch, output_return,
13340 sparc_flat_save_restore, sparc_flat_output_function_prologue,
13341 sparc_flat_output_function_epilogue): Prettify
13343 (output_function_epilogue): Likewise and add code to output
13344 deferred case vectors.
13345 (output_v9branch): Likewise, add new arg INSN and use it to tack
13346 on branch prediction settings. All callers changed.
13347 (print_operand): Likewise and output %l44 for LO_SUMs when
13349 (sparc_splitdi_legitimate): New function to make sure DImode
13350 splits can be run properly when !arch64.
13351 (sparc_initialize_trampoline, sparc64_initialize_trampoline):

13359 (sparc_emit_set_const32): New function to form 32-bit constants in
13360 registers when that requires more than one instruction.
13361 (safe_constDI, sparc_emit_set_const64_quick1,
13362 sparc_emit_set_const64_quick2, sparc_emit_set_const64_longway,
13363 analyze_64bit_constant, const64_is_2insns,
13364 create_simple_focus_bits, sparc_emit_set_const64): New functions

13367 loading for all code models on v9.
13368 * config/sparc/sparc.h (CONDITIONAL_REGISTER_USAGE): Do not make

13371 (SECONDARY_INPUT_RELOAD_CLASS, SECONDARY_OUTPUT_RELOAD_CLASS): Fix
13372 inaccuracies in comments, add symbolic and text_segment operands
13373 when TARGET_CM_MEDANY and TARGET_CM_EMBMEDANY respectively. Use
13374 GENERAL_REGS in these cases as a temp REG is needed to load these
13375 addresses into a register properly.
13376 (EXTRA_CONSTRAINT): Document more accurately, remove Q case as it
13378 (GO_IF_LEGITIMATE_ADDRESS): Allow TFmode for LO_SUM on v9 since fp
13379 quads are guaranteed to have 16-byte alignment.
13380 (LEGITIMIZE_ADDRESS): For SYMBOL_REF, CONST, and LABEL_REF use
13381 copy_to_suggested_reg instead of explicit LO_SUM and HIGH.

13397 mem_min_alignment, small_int_or_double): Add externs.
13398 * config/sparc/sparc.md: Document the many uses of UNSPEC and
13399 UNSPEC_VOLATILE in this backend.
