From: Giulio Benetti Date: Fri, 14 Jun 2019 21:03:38 +0000 (+0200) Subject: package/fxload: re-enable package on microblaze X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f00d6ddf5081b0c366827803915ccf9cf9697cf5;p=buildroot.git package/fxload: re-enable package on microblaze Building fxload on Microblaze with gcc < 8.x and optimization enabled fails with: Error: operation combines symbols in different segments This is due to gcc bug 63261 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63261). To work around this, the fxload package has a !BR2_microblaze dependency. However, gcc bug 63261 only triggers when optimization is enabled, so a better work around is to pass -O0, which is what we do in other Buildroot packages to work around this bug. So, this commit passes -O0 when BR2_TOOLCHAIN_HAS_GCC_BUG_63261, and re-enables fxload on Microblaze.
