[LLVMdev] Specify the volatile access behaviour of the memcpy, memmove and memset intrinsics
...latile flag and rework the MemIntrinsic hierarchy to provide (is|set)SrcVolatile(), (is|set)DestVolatile() and implement (set|is)Volatile in terms of the former 2 methods. This will conservatively preserve semantics. No functional change so far. Commit 1 & 2. 3. Audit all uses of isVolatile() / setVolatile() and move them to the more precise form. From this point, more aggressive / precise optimizations can happen. Commit 3. 4. Teach clang to use the new form. 5. Optionally remove the old interface form,as there should be no in-tree users left. This would however be an API change breaking external c...
