[PATCH] D70821: [SystemZ] Implement the packed stack layout

[Jonas Paulsson via Phabricator via llvm-commits]

jonpa added a comment.

Forgot: Patch was updated with a bugfix so that the RegSaveAreaUsage is set in the constructor already, so that this is always done.

Everything seems NFC now with

     bool usePackedStack(MachineFunction &MF) {
  +    return false;
       bool HasPackedStackAttr = true;
