Hi All, I'd like to add HLE support in LLVM/clang consistent to GCC's style [1]. HLE from Intel TSX [2] is legacy compatible instruction set extension to specify transactional region by adding XACQUIRE and XRELEASE prefixes. To support that, GCC chooses the approach by extending the memory order flag in __atomic_* builtins with target-specific memory model in high bits (bit 31-16 for target-specific memory model, bit 15-0 for the general memory model.) To follow the similar approach, I propose to change L...
