- * x-convex (CCLIBFLAGS): Build libgcc1 with -tm c1 so it can't
- cause executables to become c2-only.
-
- * xm-convex.h: Remove workarounds for OS 8.0 no longer needed.
- (bcopy, bzero): Define to use memcpy and memset, to get them inlined.
-
- * convex[123*].h (CC1_SPEC, CPP_SPEC, LIB_SPEC): Move to convex.h.
-
- * convex.h (TARGET_FLAGS): Add -mvolatile-[no]cache.
- (TARGET_FLAGS, LONG_TYPE_SIZE): add -mlong{32,64}.
- (target_cpu): Define, enumeration for targets to use instead of flags.
- (TARGET_C34, TARGET_C38): Add. 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. Indirect addresses are no longer used.
- (ADJUST_COST): Define.
- (TARGET_FLOAT_FORMAT): Define as VAX_FLOAT_FORMAT. Also
- accurately describes the semantics (not the bit pattern)
- of convex ieee mode.
- (REAL_VALUE_ATOF): Define, to prevent real.c from constructing
- vax dfloats. Apparently it doesn't do gfloat.
- (CHECK_FLOAT_VALUE): Call convex.c.
- (ASM_FILE_START): Output appropriate .fpmode pseudo op.
- (ASM_IDENTIFY_GCC): Ouput a zero after gcc2_compiled to keep it
- from hiding the real name from profilers and adb.
- (ASM_OUTPUT_DOUBLE, _FLOAT): Use hex to avoid /bin/as conversion
- errors.
- (ASM_DECLARE_FUNCTION_NAME): Define; call convex.c.
- (PRINT_OPERAND, _ADDRESS): Call convex.c.
- (EXIT_BODY): Define for libgcc2. 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.
