+ * genemit.c (gen_expand): Do not emit "_done" or "_fail" labels.
+ (gen_split): Likewise.
+ (main): Rework generated definitions of DONE and FAIL so that they
+ no longer use gotos. Avoids warnings about unused labels.
+
* integrate.c (copy_rtx_and_substitute): Rework to avoid need for
unused "junk" variable.
