Bonjour la liste,
Avez vous réussi à compiler GCC trunk sur Debian/Trixie/x86-64 (mon processeur est un AMD Ryzen Threadripper 2970WX) ?
Considérant le dernier commit the GCC qui est installé chez moi
dans /usr/src/Lang/gcc
commit 8b9b696c98def874139effc0380929df4a4356f0 (HEAD -> master, origin/trunk, origin/master, origin/HEAD)
Author: Haochen Jiang <haochen.jiang@intel.com>

testsuite: Add -march=x86-64-v3 to AVX10 testcases to slience warning for GCC built with AVX512 arch
Currently, when build GCC with config --with-arch=native on AVX512
machines, if we run AVX10.2 testcases, we will get vector size warnings.
It is expected but annoying. Simply add -march=x86-64-v3 to override
--with-arch=native to slience all the warnings.
gcc/testsuite/ChangeLog:
et je le compile dans /usr/src/Lang/_Gcc
'/usr/src/Lang/gcc/configure' '--with-gcc-major-version-only' '--enable-maintainer-mode' '--enable-lto' '--enable-host-shared' '--enable-gold' '--enable-plugins' '--enable-languages=c,c++,jit,lto'
et ça échoue avec:
