`-fomit-frame-pointer', we would lack the DW_CFA_advance_loc information for a lot of function, and then they would be `0'. The linker (at least on Darwin) needs to encode the stack size. In some cases, the stack size is too large to directly encode. So the linker checks to see if there is a "subl $xxx,%esp" instruction at the point where the `DW_CFA_def_cfa_offset' says the pc was. If so, the compact encoding records the offset in the function to where the stack size is embedded. But because the `DW_CFA_advance_loc' instructions are missing, it looks before the function and dies. So, instead of emitting the EH debug label before the stack adjustment operations, emit it afterwards, right before the frame move stuff. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@72898 91177308-0d34-0410-b5e6-96231b3b80d8
