With the release upcoming we've switched to reviewing blockers and desirable changes. * NEW/NOBODY 290 patches * [v7] elf: Properly align all PT_LOAD segments [BZ #28676] * Adhemerval to review alignment patch. * linux: Fix ancillary 64-bit time timestamp conversion (BZ #28349, BZ #28350) * Florian to review. * posix: Add terminal control setting support for posix_spawn * Carlos to finish review Monday. * Multiple rtld-audit fixes * Adhemerval to rebase patch set. * Szabolcs looked at the aarch64 pieces and gave feedback. * Properly handle --disable-default-pie * Siddhesh is going to look at this. * Carlos and Adhemerval discussed 64-bit time_t testing. * No way to change library default time_t size, just testing can test it. * Prelink discussion * Adhemerval: May I submit patches to remove prelink? * Carlos: Yes. * Discussed Intel, Arm, Linaro involvement in prelink. * Carlos: IHVs and ISVs need to invest upstream if they want to see prelink maintained. * Paul sends his regrets and includes two items: * I have done a review of the accuracy of the libmvec functions (in master) both with sse4.2, avx2 and avx512. Apart from a minor issue with atan2 in binary64 which was fixed (#28765), I found no error larger than 4 ulps, both in binary32 and binary64. * we are making good progress in the CORE-MATH project: 17 out of 26 functions are now available in single precision (binary32). See https://homepages.loria.fr/PZimmermann/CORE-MATH/. In most cases the correctly-rounded CORE-MATH code outperforms the GNU libc one (see the "perf" graphs). The only exceptions so far are the cosf function on i7, and the expf function. -- Cheers, Carlos.
