builtins.c: Implement support for sincos function.
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.
