Source: gcc-13
Version: 13.1.0-2
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: timestamps
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

The build dates and timestamps are embedded in various files shipped in
documentation.

The attached patches fix this by adding SOURCE_DATE_EPOCH support to the
doxygen scripts used to generate the libstdc++ documentation, and by
adjusting debian/rules2 to remove the leftover _formulas.log files from
the generated package.

According to my local tests, applying these patches should allow gcc-13
to build reproducibly with stable build paths and
DEB_BUILD_OPTIONS="nocheck nolto nopgo".


Thanks for maintaining gcc-13!


live well,
