Subject: [Buildroot] [git commit branch/2019.11.x] package/python-brotli: fix build failure due to gcc bug 68485
Date: Sat, 7 Dec 2019 12:06:41 +0100 [thread overview]
Message-ID: <20191207110229.B127788436@busybox.osuosl.org> (raw)
commit: https://git.buildroot.net/buildroot/commit/?id=1353e0cb4ae5feff4bc1cc7ac79dd1b74a9aa228
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.11.x
The python-brotli package exhibits gcc bug 68485 when built for the
Microblaze architecture with optimization enabled, which causes a build
failure.
As done for other packages in Buildroot work around this gcc bug by
setting optimization to -O0 if BR2_TOOLCHAIN_HAS_GCC_BUG_68485=y.
