Hi, Something commited a few days ago had resulted in a serious performance hit for SPEC sixtrack on 64 bits machines... The obvious suspect is Sebastian Pop's scev patch. The affected targets are at least AMD64 [1] and PPC64 [2] but not i686 [3].
Sebastian, any idea what might have caused this? Gr.
