[llvm-dev] JIT tests on AArch64 (original) (raw)

Hi all,

I am seeing a number of JIT unit test failures on AArch64. Some googling returns past discussions (circa 2014) but as far as I can tell, everything should be working. I listed the failures below.

These are from a Release build. A Debug build does not exhibit the failures. I built with gcc 6.1.0 on SuSE 12. Switching to gcc 8.2.0 also makes the problem go away, both in Debug and Release builds.

Is there a known problem with gcc 6.1.0 on AArch64? I considered the possiblity that the tests (or libraries) somehow wander into undefined behavior territory but my guess is that's unlikely.
