Giulio, All,
On 2022-09-10 00:15 +0200, Giulio Benetti spake thusly:
> With Microblaze Gcc version <= 12.x the build fails due to gcc bug 68485:
Since the latest gcc versin is 12.x, then "gcc <= 12.x" actually means
all versions of gcc, no?

Since you said the bug only appears for microblaze, gcc <= 12, and this
specific gcc bug, then shouldn't all three conditions be used?
(excluding gcc version because of my earlier comment):
ifeq ($(BR2_microblaze)$(BR2_TOOLCHAIN_HAS_GCC_BUG_68485),yy)
I.e. there is no reason to penalise other architectures, since only
micrbolaze is impacted by that bug.
Regards,
Yann E. MORIN.
