IRC: #glibc on OFTC.

Review new patches and restart review at the top.

 * State NEW, Delegate NOBODY, 304 patches.
 * Series 4140, Improve hypot(), Adhemerval to rebase.
  * Needs rebase after HJs benchtests/Makefile change.
 * Series 4116, [v14,1/4] String: Add support for __memcmpeq() ABI on all targets
  * Looks OK.
 * Series 4105, powerpc: Use the correct flag for 32-bit known libraries
  * This looks like old a.out code is blocking this.
  * Carlos & Florian to bring up with IBM.
 * Series 4101, Add missing math functions to benchtests (Sunil Pandey)
  * Adding functions to libmvec
  * Adding benchmark data for existing libmvec functions.
  * For each function we have both double and float.
  * In order to generate the microbenchmarks for float we need float and double.
  * Sunil copied the input from double to float.
 * Series 4056, manual: remove an obsolete requirement on aligned_alloc() usage
  * Carlos to ask Martin Sebor.
  * Update 2021-10-25: Asked Martin for comment.

 * Series 3961, [PING,8] localedata: add new locale ab_GE
  * First issues: No feedback from Rafal and Mike (other locale maintainers).
  * Second issue: Consensus on header.
   * Carlos to respond on the second issue with new thread.
   * https://sourceware.org/pipermail/libc-alpha/2021-September/130692.html
 * Series 3949, regex: fix buffer read overrun in search [BZ#28470]
  * Stuck on review. Needs v2. Marked Changes Requested given Andreas' comments.
 * Series 3941, Benchtests: Improve bench-memcpy-random
  * Siddhesh to look at improvement and reveiw.
 * Series 3895, [v2] elf: Support DT_RELR relative relocation format [BZ #27924]
  * Unknown dynamic tags are ignored by old glibc.
   * Old glibc must fail when running the new binary.
   * Need to add symbol dependency or bump ELF OSABI.
  * lld is there for review, but additional patches are needed to build glibc for tests.
   * More work is required in the tree to get lld working.
   * If the testsuite fails to build we can't talk about regressions easily.
   * What is the status of lld building with glibc?
    * Carlos: Ask on thread about status of lld to build glibc.
 * HJ: Testing gcc with glibc 2.34 issues.
  * Sanitizer libraries has a hack that they assume dlsym malloc is always freed.
   * In glibc 2.34 in dlsym we do 2 mallocs and then do 2 frees. Hack doesn't work.
  * https://bugs.llvm.org/show_bug.cgi?id=52278
 * Adhemerval: 64-bit time_t receive message fix.
