  28    This is a copy of diagnostic-test-inlining-1.c, but with -O1.

  30    Ideally the diagnostics subsystem would report:
  31      In function 'foo', inlined from 'bar' at LOC A, inlined from 'main' at LOC B:
  32    but with -O1 it only reports:
  33      In function 'foo', inlined from 'main' at LOC A:
  34
  35    This test case captures this behavior.  */
