toolchain.eclass: add workaround for hybrid CPUs #35877
Conversation
Signed-off-by: Sam James <sam@gentoo.org>
Hybrid/big.little/PE CPUs may report an inconsistent cache size across cores which can cause GCC's bootstrapping to fail its self-comparison. When CBUILD is amd64 or x86 and -march=native is in CFLAGS, iterate over all cores and record l1-cache-size. If any differ, use the first one we found.
