[PATCH] D132987: [PPC] Add RM as call preserved register

[Guozhi Wei via Phabricator via llvm-commits]

Carrot added a comment.

If RM is not preserved by a function call, then in the following example

  void foo(double a, double b, double *p) {
    *p++ = a + b;
    bar();
    *p = a + b;
  }

The expression a+b can not be CSEd, right?
