* optabs.h (enum optab_index): Add new OTI_expm1.
(expm1_optab): Define corresponding macro.
* optabs.c (init_optabs): Initialize expm1_optab.
* genopinit.c (optabs): Implement expm1_optab using expm1?f2
patterns.
* builtins.c (expand_builtin_mathfn): Handle BUILT_IN_EXPM1{,F,L}
using expm1_optab.
(expand_builtin): Expand BUILT_IN_EXPM1{,F,L} using
expand_builtin_mathfn if flag_unsafe_math_optimizations is set.
* config/i386/i386.md (expm1df2, expm1sf2, expm1xf2): New expanders
to implement expm1, expm1f and expm1l built-ins as inline x87
intrinsics.
testsuite:
* gcc.dg/builtins-34.c: Also check expm1*.
