X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e8fca6ce38e43565799dbce3f1648d1d01be1a96;p=gcc.git

(dbxout_type): Re-enable debugging output for anonymous structures.

(dbxout_type): Re-enable debugging output for anonymous
structures.  Change all three places that refer to xrefs to use
exactly the same condition.
