Review new patches and restart review at the top. * State NEW delegate NOBODY at 222 * Carlos' SLI at 163 days. * Starting at 65235 * Started discussing Arjun's failures on s390x. * Florian: Fedora builds against the z13 baseline. * Related commit: 22999b2f0fb62eed1af4095d062bd1272d6afeb1 * Related commit: 7ea510127e2067efa07865158ac92c330c379950 * Adhemerval: s390x build tests: * -march=z900, -march=z10, -march=z196, default * Review the earlier commits for impact on z13 * Review build-many-glibcs configuration with -march= baselines for testing. * Adhemerval noted that Gentoo was discussing stable backport policy. * The open question is about hardware performance backports. * 65235: Added Redirects to longdouble error functions [BZ #29033] * Impacts ppc64le ieee754 long double. IBM to review? * build: All microbenchmarks should output in JSON. (bug 27740) * Ask Siddhesh to review. * Remap __GLIBC_FLT_EVAL_METHOD to 0 if __FLT_EVAL_METHOD__ is -1 * Needs senior review for generic code. Will come back to this next week. * [v2] C2x scanf binary constant handling (Joseph) * Adhemerval to review. * implement dlmem() with audit extensions (Stas Sergeev) * Adhemerval: dlmem() needs some very specific requirements and memory cannot follow what dlopen will do regarding mmap flags. * Carlos: What is our use case here? Why? * Florian: Use memfd? Security review will eventually block fds since it can be used to inject created code. * Needs senior reviewer to discuss use cases. * Carlos will review the use case on list. * i386: Use pthread_barrier for synchronization on tst-bz21269 (Adhemerval) * Carlos to ask DJ to review for CI/CD impact. * Szabolcs: What about libmvec review? * Raising the minimum requirement to gcc 10. Distro gcc? * Florian: It is possible to build libmvec only if gcc is 10 or newer? * Historically libmvec has different versions and we had an Intel, AMD, and GNU ABI. * Some projects also implement what libmvec does in a single DSO to override. * Carlos: For rpm-based distros you could backport libmvec.so. * Florian: For libcrypt we define the function in the header and not always include it. * Adhemerval: Do we define the prototype? * Carlos: Yes, gcc has to know, and you add the pragma. * Szabolcs: No header magic yet. Explicit decls. Manually call the symbols. * Carlos: The risk is not at the distro level, because glibc 2.38 using distros will use newer gcc, so raising the baseline is less risk. The risk is in the glibc/gcc developer workflow impact. * Szabolcs: Making the libmvec.so non-optional seems safer. -- Cheers, Carlos.
