Apparently the IL GCC emits on some targets (arm and aarach64 with mabi=ilp32, and powerpc64 to name the three where the failures have been pointed out) isn't handled by the uninit pass and so it doesn't issue the expected warning. That might be a new (as in previously unknown) limitation in the warning or one I don't remember coming across. I don't see excess warnings with my arm-eabi cross-compiler. What are they in your environment? I have limited the test to just x86_64 for now and repurposed pr100073 where the same failure was reported on powerpc64 to track the missing warning on these targets. Martin
