* optabs.h (enum optab_index): Add new OTI_logb and OTI_ilogb. (logb_optab, ilogb_optab): Define corresponding macros. * optabs.c (init_optabs): Initialize logb_optab and ilogb_optab. * genopinit.c (optabs): Implement logb_optab and ilogb_optab using logb?f2 and ilogb?i2 patterns. * builtins.c (expand_builtin_mathfn): Handle BUILT_IN_LOGB{,F,L} using logb_optab, and BUILT_IN_ILOGB{,F,L} using ilogb_optab. (expand_builtin): Expand BUILT_IN_LOGB{,F,L} and BUILT_IN_ILOGB{,F,L} using expand_builtin_mathfn if flag_unsafe_math_optimizations is set. * reg-stack.c (subst_stack_regs_pat): Handle UNSPEC_XTRACT_FRACT and UNSPEC_XTRACT_EXP. * config/i386/i386.md (*fxtractdf3, *fxtractsf3, *fxtractxf3): New patterns to implement fxtract x87 instruction. (logbdf2, logbsf2, logbxf2, ilogbsi2): New expanders to implement logb, logbf, logbl, ilogb, ilogbf and ilogbl built-ins as inline x87 intrinsics. (UNSPEC_XTRACT_FRACT, UNSPEC_XTRACT_EXP): New unspecs to represent x87's fxtract insn. * gcc.dg/builtins-38.c: New test. git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@80709 138bc75d-0d04-0410-961f-82ee72b054a4
