Subject: package/postgresql: work around gcc bug 85180
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5bbcccad9d2c218c959d5deda384d9e88a24d700;p=buildroot.git

package/postgresql: work around gcc bug 85180

With Microblaze Gcc version < 8.x the build hangs due to gcc bug
85180: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180. The bug
shows up when building postgresql with optimization but not when
building with -O0. To work around this, if
BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y we force using -O0.

Fixes:
