From aef94a0f415f1b061e801ced6f2f9c104fe0e9e5 Mon Sep 17 00:00:00 2001 From: uros Date: Sat, 4 Sep 2004 07:55:12 +0000 Subject: 2004-09-04 Uros Bizjak * builtins.c (expand_builtin_mathfn): Handle BUILT_IN_RINT{,F,L} using rint_optab. (expand_builtin): Expand BUILT_IN_RINT{,F,L} using expand_builtin_mathfn. * genopinit.c (optabs): Rename trunc_optab to btrunc_optab. Use btrunc?f patterns for btrunc_optab. Implement rint_optab using rint?f patterns. * optabs.c (init_optabs): Initialize rint_optab. * optabs.h (enum optab_index): Rename OTI_trunc to OTI_btrunc. Add new OTI_rint. (btrunc_optab): Rename macro from trunc_optab. (rint_optab): Define corresponding macro. * reg-stack.c (subst_stack_regs_pat): Handle UNSPEC_FRNDINT_FLOOR, UNSPEC_FRNDINT_CEIL, UNSPEC_FRNDINT_TRUNC, UNSPEC_FRNDINT_MASK_PM. * config/i386/i386-protos.h (emit_i387_cw_initialization): Change prototype. Add new int parameter. * config/i386/i386.c (emit_i387_cw_initialization): Handle new rounding modes. * config/i386/i386.h (enum fp_cw_mode): Delete. (MODE_NEEDED): Handle new rounding modes. (EMIT_MODE_SET): Change condition to handle new rounding modes. * config/i386/i386.md (UNSPEC_FRNDINT_FLOOR, UNSPEC_FRNDINT_CEIL, UNSPEC_FRNDINT_TRUNC, UNSPEC_FRNDINT_MASK_PM): New unspecs to represent different rounding modes of frndint insn. (type): Add frndint type. (i387, length, memory): Handle this type. (i387_cw): New attribute definition. (*fix_truncdi_1, fix_truncdi_nomemory, fix_truncdi_memory, *fix_truncsi_1, fix_truncsi_nomemory, fix_truncsi_memory, *fix_trunchi_1, fix_trunchi_nomemory, fix_trunchi_memory): Add "i387_cw" attribute defined to "trunc". (x86_fnstcw_1): Remove comment. (*frndintxf2): Rename insn definition to frndintxf2. Move insn definition near rint?f2 expanders. (rintdf2, rintsf2, rintxf2): New expanders to implement rint, rintf and rintl built-ins as inline x87 intrinsics. (frndintxf2_floor): New pattern to implement floor rounding mode with frndint x87 instruction. (floordf2, floorsf2, floorxf2): New expanders to implement floor, floorf and floorl built-ins as inline x87 intrinsics. (frndintxf2_ceil): New pattern to implement ceil rounding mode with frndint x87 instruction. (ceildf2, ceilsf2, ceilxf2): New expanders to implement ceil, ceilf and ceill built-ins as inline x87 intrinsics. (frndintxf2_trunc): New pattern to implement trunc rounding mode with frndint x87 instruction. (btruncdf2, btruncsf2, btruncxf2): New expanders to implement trunc, truncf and truncl built-ins as inline x87 intrinsics. (frndintxf2_mask_pm): New pattern to implement rounding mode with exceptions with frndint x87 instruction. (nearbyintdf2, nearbyintsf2, nearbyintxf2): New expanders to implement nearbyint, nearbyintf and nearbyintl built-ins as inline x87 intrinsics. * testsuite/gcc.dg/builtins-46.c: New. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@87076 138bc75d-0d04-0410-961f-82ee72b054a4 --- gcc/reg-stack.c | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'gcc/reg-stack.c') diff --git a/gcc/reg-stack.c b/gcc/reg-stack.c index 04220bf0b2d..fc13759af49 100644 --- a/gcc/reg-stack.c +++ b/gcc/reg-stack.c @@ -1728,6 +1728,12 @@ subst_stack_regs_pat (rtx insn, stack regstack, rtx pat) case UNSPEC_COS: case UNSPEC_FRNDINT: case UNSPEC_F2XM1: + + case UNSPEC_FRNDINT_FLOOR: + case UNSPEC_FRNDINT_CEIL: + case UNSPEC_FRNDINT_TRUNC: + case UNSPEC_FRNDINT_MASK_PM: + /* These insns only operate on the top of the stack. */ src1 = get_true_reg (&XVECEXP (pat_src, 0, 0)); -- cgit v1.2.1
