Subject: builtins.c (expand_builtin_pow): If flag_unsafe_math_optimizations isn't set...
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=13b598498325a06ab991fbbb2d3a739a99c52082;p=gcc.git

builtins.c (expand_builtin_pow): If flag_unsafe_math_optimizations isn't set...


	* builtins.c (expand_builtin_pow): If flag_unsafe_math_optimizations
	isn't set, don't call expand_builtin_mathfn_2 to use the pow optab.
	(expand_builtin): Always call expand_builtin_pow.
