- cfi directives are not inserted at the right location or in the right order. - The source MachineLocation for the cfi directive that changes the cfa register to $fp should be MachineLocation::VirtualFP. - A PROLOG_LABEL that marks the beginning of cfi_offset directives for callee-saved register is emitted even when no callee-saved registers are saved. - When a callee-saved double precision register is saved, two cfi_offset directives, one for each of the paired single precision registers, should be emitted. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132703 91177308-0d34-0410-b5e6-96231b3b80d8
