Subject: package/atop: work around gcc bug 85180
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b0545135e71052daf90dba8c82e6e750c333dde1;p=buildroot.git

package/atop: 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 atop 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:
