It's been so long and so many changes since these tests were regression guards, that the original target has lost importance. Heck, it was even xfail lp64 at one time! According to my git dig, it's been adjusted for pass changes, including reordering and dump output changes. But you know that; you've been instrumental in many of those changes. :) I'd say gcc.target/arm/ is the one target that's *not* plausible, as according to Alex result differs between subtargets. > I read from your messages that the testcases pass on arm*-*-*? Yes: they pass (currently XPASS) on arm-eabi and arm-unknown-linux-gnueabi, default configurations. But, scev-3 and -5 fail with for example -mcpu=cortex-r5 brgds, H-P PS. I'm open to just reverting the patch. The s/ia32/ilp32/ is proven wrong.
