--- Comment #9 from Kewen Lin <linkw at gcc dot gnu.org> --- I filed one new bug PR108415 for the ICE itself to avoid the confusion here. This ICE is not a regression, it's a latent bug, because: 1) Without the culprit commit r13-4894 (like using r13-4893 or reverting it), if we specify one more explicit option -m64, we can see the exactly same ICE. It's just concealed as we emit error first on Linux without -m64. (r13-4894 changed it not to emit error any more so no error to conceal then). 2) It's even nothing to do with powerpc64 handling, this ICE can be produced on ppc64 Linux with options "-m32 -mcpu=401 -mmodulo", so it's not 64 bit specific (so not powerpc64 handling related either). I put one comment about root cause of this ICE in PR108415.
