Subject: etags: work around GCC bug 114882
X-Git-Tag: archive/raspbian/1%30.1+1-3+rpi1^2~2^2~20^2~1724
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=ca4f0705be544986f11971bd8ee7dc30a8d444f1;p=emacs.git

etags: work around GCC bug 114882

* lib-src/etags.c: Ignore -Wanalyzer-use-of-uninitialized-value.
This applies to the whole source file, not just to areas where GCC
has bugs, as it was too tricky to ignore more selectively.
