[LLVMdev] OT: intel darwin losing primary target status
...describe the function epilog. If you
run dwarfdump --eh-frame on the .o files made with the new compiler,
you'll see extra dwarf unwind instructions at the end like:
...
DW_CFA_advance_loc4 (64) #<-- advance to near end of
function
DW_CFA_restore (rbp)
DW_CFA_def_cfa (rsp, 8)
DW_CFA_nop
DW_CFA_nop
The linker's conversion to compact unwind "runs" the dwarf unwind info
for a function and then records the state at the end. Adding unwind
info for the epilog breaks this. In...
