8611 The strategy we now use is to pre allocate the top_elt along
8612 with the EH context so that each thread has its own top_elt.

14720 Rewrite Sparc backend for better code generation and
14721 improved sparc64 support.
14722 * config/sparc/sp64-elf.h: Set JUMP_TABLES_IN_TEXT_SECTION to
14724 * config/sparc/sysv4.h: Likewise.
14725 * config/sparc/sparc.c (v8plus_regcmp_p, sparc_operand,
14726 move_operand, v8plus_regcmp_op, emit_move_sequence,
14727 singlemove_string, doublemove_string, mem_aligned_8,
14728 output_move_double, output_move_quad, output_fp_move_double,
14729 move_quad_direction, output_fp_move_quad, output_scc_insn):
14731 (small_int_or_double): New predicate.
14732 (gen_compare_reg): Remove TARGET_V8PLUS cmpdi_v8plus emission.
14733 (legitimize_pic_address): Emit movsi_{high,lo_sum}_pic instead of
14734 old pic_{sethi,lo_sum}_si patterns.
14735 (mem_min_alignment): New generic function to replace
14736 mem_aligned_8, which uses REGNO_POINTER_ALIGN information when
14737 available and can test for arbitrary alignments. All callers
14739 (save_regs, restore_regs, build_big_number,
14740 output_function_prologue, output_cbranch, output_return,
14741 sparc_flat_save_restore, sparc_flat_output_function_prologue,
14742 sparc_flat_output_function_epilogue): Prettify
14744 (output_function_epilogue): Likewise and add code to output
14745 deferred case vectors.
14746 (output_v9branch): Likewise, add new arg INSN and use it to tack
14747 on branch prediction settings. All callers changed.
14748 (print_operand): Likewise and output %l44 for LO_SUMs when
14750 (sparc_splitdi_legitimate): New function to make sure DImode
14751 splits can be run properly when !arch64.
14752 (sparc_initialize_trampoline, sparc64_initialize_trampoline):
14753 Reformat example code in comments.

14759 sparc_output_deferred_case_vectors): New functions to output them.
14760 (sparc_emit_set_const32): New function to form 32-bit constants in
14761 registers when that requires more than one instruction.
14762 (safe_constDI, sparc_emit_set_const64_quick1,
14763 sparc_emit_set_const64_quick2, sparc_emit_set_const64_longway,
14764 analyze_64bit_constant, const64_is_2insns,
14765 create_simple_focus_bits, sparc_emit_set_const64): New functions
14766 which do the same for 64-bit constants when arch64.

14768 loading for all code models on v9.
14769 * config/sparc/sparc.h (CONDITIONAL_REGISTER_USAGE): Do not make

14771 (ALTER_HARD_SUBREG): Fix thinko, return REGNO + 1 not 1.
14772 (SECONDARY_INPUT_RELOAD_CLASS, SECONDARY_OUTPUT_RELOAD_CLASS): Fix
14773 inaccuracies in comments, add symbolic and text_segment operands
14774 when TARGET_CM_MEDANY and TARGET_CM_EMBMEDANY respectively. Use
14775 GENERAL_REGS in these cases as a temp REG is needed to load these
14776 addresses into a register properly.
14777 (EXTRA_CONSTRAINT): Document more accurately, remove Q case as it
14779 (GO_IF_LEGITIMATE_ADDRESS): Allow TFmode for LO_SUM on v9 since fp
14780 quads are guaranteed to have 16-byte alignment.
14781 (LEGITIMIZE_ADDRESS): For SYMBOL_REF, CONST, and LABEL_REF use
14782 copy_to_suggested_reg instead of explicit LO_SUM and HIGH.

14798 mem_min_alignment, small_int_or_double): Add externs.
14799 * config/sparc/sparc.md: Document the many uses of UNSPEC and
14800 UNSPEC_VOLATILE in this backend.
