--- Comment #3 from Yury Gribov <ygribov at gcc dot gnu.org> --- Created attachment 41822 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=41822&action=edit Patch to disable test on PowerPC (In reply to Yury Gribov from comment #2) > pr56727-2.c is interesting, it does not repro on x86. Ok, pr56727-2 fails because it gets optimized by tailcall pass (which is even more agressive at optimizing recursive calls). I worked around this (by prohibiting tailcalls) but generated assembly is too different from x86. So perhaps simply disable this test on Power? Patch attached.
