2004-04-13 Uros Bizjak <uros@kss-loka.si>:
* optabs.c (expand_twoval_unop): Reorder function arguments.
* builtins.c (expand_builtin_mathfn_3): Update calls to
expand_twoval_unop.
* reg-stack.c (subst_stack_regs_pat): Handle UNSPEC_TAN_ONE
and UNSPEC_TAN_TAN. Add missing comment.
* config/i386/i386.md (*tandf3_1, *tansf3_1, *tanxf3_1): New
patterns to implement fptan x87 instruction.
(tandf2, tansf2, tanxf2): New expanders to implement tan, tanf
and tanl built-ins as inline x87 intrinsics. Define corresponding
peephole2 optimizers for 'fptan; fstp %st(0); fld1' sequence.
(UNSPEC_TAN_ONE, UNSPEC_TAN_TAN): New unspecs to represent
x87's fptan insn.
* gcc.dg/i386-387-1.c: Add new test for __builtin_tan.
* gcc.dg/i386-387-2.c: Likewise.
* gcc.dg/i386-387-7.c: New test.
* gcc.dg/i386-387-8.c: New test.
* gcc.dg/builtins-37.c: New test.
