[LLVMdev] How to make sure llvm.memset intrinsic is not lowered into memset() call?
Hi llvmdev!
There are cases when we want our instrumentation passes for Sanitizer tools
to insert llvm.memset.* calls (basically, we want to mark certain region of
user memory as (un)addressable by writing magic values for "shadow" of that
memory region). llvm.memset are convenient:
(1) we don't have to manually emit all these n-byte stores in a cycle.
(2) llvm.memset can be inlined
