Subject: [PATCH] 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.
