--- Comment #24 from mwahab at gcc dot gnu.org --- Created attachment 39055 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=39055&action=edit Testcase for ICE on arm targets Attached vshuf-v64qi.i for the ICE on arm targets. The failure is triggered with -mfloat-abi=hard -O1. The cc1 command line is: ---- cc1 vshuf-v64qi.i -mfloat-abi=hard -O1 ---- The float-abi option is suspicious but I get the same failure when -march=armv8-a -mfpu=neon-fp-armv8 is added so I don't think that it's the lack of FP registers that's the problem.
