A frame pointer must be used if stack pointer is modified after the prologue. LLVM will emit pushf/popf if we need to save/restore the FLAGS register, requiring us to have a frame pointer for the function. There is a small twist: this sequence might exist in user code via inline-assembly. For now, conservatively assume that such functions require a frame pointer. For real world justification, please see clang's implementation of __readeflags. This fixes PR25945. llvm-svn: 256456 |
