optabs.h (enum optab_index): Add new OTI_ldexp.
* optabs.h (enum optab_index): Add new OTI_ldexp.
(ldexp_optab): Define corresponding macro.
* optabs.c (init_optabs): Initialize ldexp_optab.
* genopinit.c (optabs): Implement ldexp_optab using ldexp?f3
patterns.
* builtins.c (expand_builtin_mathfn_2): Handle BUILT_IN_LDEXP{,F,L}
using ldexp_optab.
(expand_builtin): Expand BUILT_IN_LDEXP{,F,L} using
expand_builtin_mathfn_2 if flag_unsafe_math_optimizations is set.
* config/i386/i386.md (ldexpsf3, ldexpdf3, ldexpxf3): New expanders
to implement ldexpf, ldexp and ldexpl built-ins as inline x87
intrinsics.
testsuite:
* gcc.dg/builtins-34.c: Also check ldexp*.
