Subject: middle-end: Remove unused internal function after IVopts cleanup [PR118756]
X-Git-Tag: basepoints/gcc-16~2158
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8d19fbb2be487f19ed1c48699e17cafe19520525;p=thirdparty%2Fgcc.git

middle-end: Remove unused internal function after IVopts cleanup [PR118756]

It seems that after my IVopts patches the function contain_complex_addr_expr
became unused and clang is rightfully complaining about it.

This removes the unused internal function.

gcc/ChangeLog:

	PR tree-optimization/118756
	* tree-ssa-loop-ivopts.cc (contain_complex_addr_expr): Remove.
