optabs.h (enum optab_index): Add new OTI_scalb.
* optabs.h (enum optab_index): Add new OTI_scalb.
(scalb_optab): Define corresponding macro.
* optabs.c (init_optabs): Initialize scalb_optab.
* genopinit.c (optabs): Implement scalb_optab using scalb?f3
patterns.
* builtins.c (expand_builtin_mathfn_2, expand_builtin): Handle
BUILT_IN_SCALB{,F,L}, BUILT_IN_SCALBN{,F,L} and BUILT_IN_SCALBLN{,F,L}.
(expand_builtin): Expand BUILT_IN_SCALB{,F,L}, BUILT_IN_SCALBN{,F,L}
and BUILT_IN_SCALBLN{,F,L} using expand_builtin_mathfn_2 if
flag_unsafe_math_optimizations is set.
* config/i386/i386.md (scalbxf3, scalb<mode>3): New expanders
to implement scalbf, scalb and scalbl built-ins as inline x87
intrinsics.
testsuite/ChangeLog
* gcc.dg/builtins-34.c: Add scalb/scalbn/scalbln cases.
