--- Comment #25 from Evan Nemerson <e...@coeus-group.com> --- Created attachment 48253 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=48253&action=edit Similar test which fails on armv7 I'm also getting an error on armv7-a for the same original code (<https://github.com/nemequ/simde/blob/2c180d0cb01c79b187b9372f1ac3afe779bff832/simde/x86/sse4.1.h#L1078>) when compiling with -O1 or above and -fstack-protector-strong. I'm not sure if it's the same issue or not; Jakub's test case from comment #12 doesn't abort with the same target and flags. I'm attaching a test test case which does trigger the issue on armv7. If it would be better to open a new bug just let me know, and if it has already been fixed sorry for the noise :( Here is the output from GCC with -v: Using built-in specs.
