spatel added a comment. The struct hack isn't obvious to me. Without that, we would produce a load with default alignment based on the size of the load (i132 -> align 4, etc)? But we want to force align 1 regardless of the load size, so the __packed__ attribute on the struct gets us that IIUC. What does __may_alias__ do?
Explain this in a code comment in the header to make this less tricky? ================ Comment at: lib/Headers/immintrin.h:359 +#endif +#endif /* __MOVEBE */ + ---------------- MOVEBE -> MOVBE https://reviews.llvm.org/D52586 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
