2004-04-06 Uros Bizjak <uros@kss-loka.si> * builtins.c: Implement support for sincos function. (expand_builtin_mathfn): Remove BUILT_IN_SIN{,F,L} and BUILT_IN_COS{,F,L}. (expand_builtin_mathfn_3): New function. (expand_builtin): Expand BUILT_IN_SIN{,F,L} and BUILT_IN_COS{,F,L} using expand_builtin_mathfn_3 if flag_unsafe_math_optimization is set. * optabs.h (enum optab_index): Add new OTI_sincos. (sincos_optab): Define corresponding macro. * optabs.c (init_optabs): Initialize sincos_optab. (expand_twoval_unop): New function. * genopinit.c (optabs): Implement sincos_optab using sincos?f3 patterns. * reg-stack.c (subst_stack_regs_pat): Handle UNSPEC_SINCOS_COS and UNSPEC_SINCOS_SIN. * config/i386/i386.md (sincosdf3, sincossf3, *sincosextendsfdf3, sincosxf3): New patterns to implement sincos, sincosf and sincosl built-ins as inline x87 intrinsics. Define splits for sindf2, sinsf2, *sinextendsfdf2, sinxf2, cosdf2, cossf2, *cosextendsfdf2 and cosxf2 patterns from corresponding sincos patterns. (sindf2, sinsf2, sinxf2): Rename to *sindf2, *sinsf2, *sinxf2. (cosdf2, cossf2, cosxf2): Rename to *cosdf2, *cossf2, *cosxf2. (UNSPEC_SINCOS_SIN, UNPEC_SINCOS_COS): New unspecs to represent x87's unspec insn. * gcc.dg/builtins-36.c: New test. From-SVN: r80463
