...Compiling this with any level of optimization for arm64 gives incorrect code, unless my test case above is triggering some undefined behaviour that I’m not aware of. Other architectures appear to work OK. $ clang -arch arm64 -O1 test.c -S -o - .section __TEXT,__text,regular,pure_instructions .ios_version_min 5, 0 .globl _getVec3 .align 2 _getVec3: ; @getVec3 ; BB#0: b _getVec2 .subsections_via_symbols - - - - I’m happy to file a bug for this, but not sure quite where it belongs - clang, LLVM or direct to Apple. Can someone test the top of tree and see if it suffers...
