These don't schedule the same as C2. - (OVERRIDE_OPTIONS): Call init routine in convex.c. - (CPP_SPEC, ASM_SPEC, LINK_SPEC): If originally bootstrapped with - an ieee compiler, produce an ieee gcc. - (LINK_LIBGCC_SPECIAL): Define, to avoid searching old libgcc.a - versions during bootstrap. - (STACK_BOUNDARY): Change from 32 to 64 -- odd-word aligned - longwords are slow on c34. - (FUNCTION_PROLOGUE): Make frame size a multiple of 8, not 4. - (FUNCTION_EPILOGUE): Output a 0 to terminate c34 icache prefetch. - (INITIAL_FRAME_POINTER_OFFSET): Make a multiple of 8. - (REG_ALLOC_ORDER): Define. Put S0 (the return register) last. - (HARD_REGNO_MODE_OK): Rewrite to make clearer. - (MODES_TIEABLE_P): Rewrite to make clearer. - (PREFERRED_RELOAD_CLASS): Rewrite to make clearer. - (S0_REGNUM, A0_REGNUM): Define. - (*_REGNUM): Write in terms of [AS]0_REGNUM instead of absolute numbers. - (enum reg_class, etc): Add SI_REGS == S_REGS + INDEX_REGS. - (REGNO_REG_CLASS, REG_CLASS_FROM_LETTER, REGNO_OK_FOR_*_P): Use tables. - (CONST_OK_FOR_LETTER_P): Change. New def passes any const_int, - rejects any const_double. - (CONST_DOUBLE_OK_FOR_LETTER_P): Change. New defs are 'G' == low - word all zeros, 'H' == high word all signs. - (EXTRA_CONSTRAINT): New. 'Q' == volatile memref. Used to generate - cache-bypass instructions when -mvolatile-nocache is set. - (RETURN_POPS_ARGS): Change, always true. - (FUNCTION_ARG_ADVANCE): Count args, not # words of args. - (FUNCTION_ARG): Return arg count to the final VOIDmode FUNCTION_ARG - hack that supplies "next arg register" to be stored in call insn. - (TRAMPOLINE_TEMPLATE): Use instruction notation rather than constants. - (INITIALIZE_TRAMPOLINE): Use gen_call_pop. - (LEGITIMATE_CONSTANT_P): Rewrite to make clearer. - (GO_IF_LEGITIMATE_ADDRESS): Do not use indirect addressing -- with - insn scheduling, two loads can be faster and can't be slower. - (SLOW_BYTE_ACCESS): Define unless C2. Memory access to bytes is - not actually slow, but faster processors don't forward partial - word writes to word reads, and setting SLOW_BYTE_ACCESS - makes the code consistently use word ops where possible. - (CONST_COSTS): Const_DOUBLE cost is zero -- if it appears, it is - immediate and therefore free. - (RTX_COSTS): areg+const is free (via indexing). - (RTX_COSTS): Provide target-dependent values for *,<<,>> - (ADDRESS_COST): Zero.

Call atexit handler if present. - - convex.md: Add scheduling info. - (movxx): One of the operands must be a register. - (movdf, movdi): Add anonymous patterns that can load an arbitrary - const_double by doing two immediate loads. This is not superior - to loading it from memory, and can be worse, so LEGITIMATE_CONSTANT_P - still rejects these constants, but the patterns are still useful - so rtx folding can produce arbitrary results. - (floatunsdidf, floatunsdisf): Add patterns that avoid double rounding. - (floatunssidf, floatunssisf): Add patterns that mimic gcc's default - method, to keep SI cvts from promoting to the above DI cvts. - (fix_truncdfsi2): Use cvtd.l even if cvtd.w is available -- on c34 - cvtd.w is microcoded and slower. - (addqi3, subqi3, mulqi3): can do immediate with word insn. - (subsi3): use sub/neg to get reverse subtract (reduces reg shuffling). - (udivsi3): give up on having sign_expand_binop do this; people keep - breaking it. Manually extend unsigned SI to signed DI, then divide. - (xshfxx3): The options rank differently on different machines, so - spell them all out and enable the appropriate ones under TARGET_Cxx. - (sqrtxx2): Put under flag_fast_math. - (sinxx2, cosxx2): I don't know why these exist, but they do, so supply - them. The other microcoded intrinsics are in convex math.h. - (txtxx): Remove, no longer necessary. - (cmpdi): Add alternative to fake "eq.l #0,sk" with "neg.l sk,scratch". - (cmpqi): Omit, seems to produce marginally better cse than the old way. - (cmpsf): Avoid compare against 0.0 in ieee mode, since -0.0 is - possible and would confuse old ucode. - (movstrsi): Add. - (anon): Add patterns to pick up on dbra optimizations and implement the - sub/test part. (This optimizes out the compare against 0.) - (call, call_value): Use _pop form instead, and let convex.c replace - the pushes with fp stores. - (end): Put local variable list back. - - convex.c (init_convex): New. Fill in tables used by convex.h. - (psw_disable_float): New. Turn off float exception enables to - make the environment more ieee-like. - (set_cmp): Change name to output_cmp. - (gen_cmp): Change name to output_condjmp. Add handling for - `neg.x' as a fake `eq.x #0' and for optimized-out compares - that read the carry of a preceding decrement. - (simplify_for_convex): New. Replace addr-(-const) with - addr+const so /bin/as will like the notation. - (expand_movstr): New. Generate pipelined load/store sequence. - (asm_declare_function_name): New. Output arg count for debuggers. - (print_operand): Moved from convex.h. Add %u and %v to fetch - subwords of a CONST_DOUBLE, %z to use in replacing shift by mul. - (print_operand_address): Moved from convex.h. - (outfloat): New, call REAL_VALUE_TO_DECIMAL. - (replace_arg_pushes): New. Replace sp by fp if possible; this does - not allow us to get rid of sp but stores are faster than pushes on - new machines. - (emit_ap_optimizations): New. Do simple live analysis of arg pointer - register and eliminate dead reloads. - - math-convex.h: removed. - fixinc.convex: new file. - -Thu May 6 22:54:43 1993 Torbjorn Granlund (tege@hal.gnu.ai.mit.edu) - - * config/we32k/we32k.h (ASM_OUTPUT_ASCII): - Cast PTR to unsigned char *. - * config/clipper/clix.h (ASM_OUTPUT_ASCII): Likewise. - -Thu May 6 20:20:41 1993 Brendan Kehoe (brendan@lisa.cygnus.com) - - * cp-decl.c (build_enumerator): Strip any no-op casts off the - value before we try to do anything with it. - - * cp-call.c (convert_harshness): Take volatility, in addition to - constness, into account when figuring out the penalty for the - type under question. - - * cp-decl.c (grokdeclarator): Undo unneeded change of Apr 6 when we - returned the type of the local typedef, instead of the typedef itself. - -Thu May 6 19:21:34 1993 Doug Evans (dje@canuck.cygnus.com) - - * reload1.c (eliminate_regs, case {PRE,POST}_{INC,DEC}): Account - for PUSH_ROUNDING. - -Thu May 6 18:17:19 1993 Richard Stallman (rms@mole.gnu.ai.mit.edu) - - * config/i386/sequent.h (DBX_OUTPUT_LBRAC, DBX_OUTPUT_RBRAC): - Override the usual definitions. - - * objc/hash.h, objc/objc.h, objc/runtime.h, objc/sarray.h: - Use gstddef.h, with doublequotes. - -Thu May 6 15:58:18 1993 Ian Lance Taylor (ian@cygnus.com) - - * fixincludes: More fixes for IRIX 4.0.1.
