[LLVMdev] [LLVMDev] About user of bitcast/GEP instruction
Hi,
In PromoteMemoryToRegister.cpp, it seems to rely on the fact that the only
users of bitcast/GEP instruction are lifetime intrinsics
(llvm.lifetime.start/end). I did some searching in llvm/test folder, it
seems to be true.
However, by reading LLVM IR manual, I don't see any restriction stated on
the possible user of bitcast/GEP instruction. So my question is who impose
the restriction ?
