Subject: Re: ILP32 for ARM64: testing with glibc testsuite

Hi all,

[add libc-alpha mail list]

For libc-alpha: this is the part of LKML submission with latest
patches for aarch64/ilp32.
https://www.spinics.net/lists/arm-kernel/msg537846.html

Glibc that I use has also included consolidation patches from Adhemerval
Zanella and me that are still not in the glibc master. The full series is:
https://github.com/norov/glibc/tree/ilp32-2.24-dev2

Below is the results of glibc testsuite run for aarch64/lp64
in different configurations. Column names meaning:
kvgv: kernel is vanilla, glibc is vanilla;
kdgv: kernel has ilp32 patches applied, but ilp32 is disabled in config; 
      glibc is vanilla;
kegv: kernel has ilp32 patches applied and ilp32 is enabled, glibc is vanilla;
kege: kernel patches are applied and enabled, glibc patches are applied.

Only different lines are shown. Full results are in attached archive. 

I didn't analyze regressions deep yet, so any ideas/suggestions are appreciated.

Yury.
