Thanks for the reduction.

I can work with this reduction, but keep in mind that it's better to disable the c-reduce pass which renames things.

The reason is that if this is a problem in SPEC that needs to be fixed, then having the names preserved would help locate which part of SPEC has the problem.

I don't remember what is the pass name you have to disabled, as I don't use c-reduce myself. But if you try c-vise instead of c-reduce, then there the renaming pass is disabled by default.
