The exclusion of BR2_GCC_VERSION_4_8_X is wrong, because we have in
Buildroot the patch fixing the
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58854 gcc bug.
But generally, I'm not really happy with this approach, as we would
have to update these dependencies every time we bump/change the
external toolchain Kconfig options... Unfortunately I don't have a
better suggestion.
Maybe I would prefer something like:
config BR2_TOOLCHAIN_HAS_GCC_BUG_58854
bool
And then the toolchain impacted by the bug would select it. For
example, are you sure the Linaro toolchains are affected by the
problem? Most likely they have backported the change that is needed to
fix this problem.
Best regards,
Thomas
