optabs.h (enum optab_index): Add new OTI_log10 and OTI_log2.
2004-02-11 Uros Bizjak <uros@kss-loka.si>
* optabs.h (enum optab_index): Add new OTI_log10 and OTI_log2.
(log10_optab, log2_optab): Define corresponding macros.
* optabs.c (init_optabs): Initialize log10_optab and log2_optab.
* genopinit.c (optabs): Implement log10_optab and log2_optab
using log10?f2 and log2?f2 patterns.
* builtins.c (expand_builtin_mathfn): Handle BUILT_IN_LOG10{,F,L}
using log10_optab, and BUILT_IN_LOG2{,F,L} using log2_optab.
(expand_builtin): Expand BUILT_IN_LOG10{,F,L} and BUILT_IN_LOG2{,F,L}
using expand_builtin_mathfn if flag_unsafe_math_optimizations is set.
* config/i386/i386.md (log10sf2, log10df2, log10xf2, log2sf2,
log2df2, log2xf2): New patterns to implement log10, log10f, log10l,
log2, log2f and log2l built-ins as inline x87 intrinsics.
* gcc.dg/builtins-33.c: New test.
