------- Comment #3 from steven at gcc dot gnu dot org 2007-10-21 10:00 ------- The way for you to narrow down the bug is this:
1. Compile with -daAP 2. Look in the .s file which instruction references the missing label. There should be a LABEL_REF with a number. 3. Grep for "code_label.*<number>" in the RTL dumps. The label should at least appear in the .expand dump. This will help you find the pass during/after which the label disappears. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33848
