optabs.h (enum optab_index): Add new OTI_log1p.
* optabs.h (enum optab_index): Add new OTI_log1p.
(log1p_optab): Define corresponding macro.
* optabs.c (init_optabs): Initialize log1p_optab.
* genopinit.c (optabs): Implement log1p_optab using log1p?f2
patterns.
* builtins.c (expand_builtin_mathfn): Handle BUILT_IN_LOG1P{,F,L}
using log1p_optab.
(expand_builtin): Expand BUILT_IN_LOG1P{,F,L} using
expand_builtin_mathfn if flag_unsafe_math_optimizations is set.
* reg-stack.c (subst_stack_regs_pat): Handle UNSPEC_FYL2XP1.
* config/i386/i386.c (ix86_emit_i387_log1p): New function.

Prototype here.
* config/i386/i386.md (UNSPEC_FYL2XP1): New unspec to represent
x87's fyl2xp1 instruction.
(*fyl2x_xf3): Rename insn definition to fyl2x_xf3.
(fyl2xp1_xf3): New pattern to implement fyl2xp1 x87 instruction.
(log1psf2, log1pdf2, log1pxf2): New expanders to implement log1pf,
log1p and log1pl built-ins as inline x87 intrinsics.
* testsuite/gcc.dg/builtins-33.c: Also check log1p*.
