Patch to implement pow(x,1.0/3.0) = cbrt(x) optimization
I have the patch that implements the optimization ready, just waiting for the
mainline to open again. Should I post it to gcc-patches anyway?
2006-07-05 Uros Bizjak <[EMAIL PROTECTED]>
* builtins.c (fold_builtin): Fold pow(x,1.0/3.0) as cbrt(x) if
flag_unsafe_math_optimizations is set.
testsuite:
* gcc.dg/builtins-8.c: Also check pow(x,1.0/3.0) to cbrt(x)
transformation.
