* reload.c (push_reload): Don't use IN as the reload reg in in-out
reload if it is set elsewhere in the insn.
Fri May 7 04:48:25 1993 Chris Smith (
* 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.
(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.
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
(ASM_DECLARE_FUNCTION_NAME): Define; call convex.c.
(PRINT_OPERAND, _ADDRESS): Call convex.c.
(EXIT_BODY): Define for libgcc2. Call atexit handler if present. 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.
