Hi,
I've installed libc6:s390x (2.35-0ubuntu3.2) from jammy-proposed repository (for Ubuntu 22.04) and successfully tested the package:
$ /lib/ld64.so.1 --version
ld.so (Ubuntu GLIBC 2.35-0ubuntu3.2) stable release version 2.35.
...
$ /lib/ld64.so.1 --list-tunables | grep hwcaps
glibc.cpu.hwcaps:
=> Now this GLIBC_TUNABLES is also available on s390x.
Furthermore I've run a small test program which calls the IFUNC'ed functions memmove, memmem, strstr and UTF8_UTF16_Z9.so via iconv-conversion from UTF16BE to UTF8.
Running gdb with setting the GLIBC_TUNABLES in different flavors like this ...
gdb$ set environment GLIBC_TUNABLES glibc.cpu.
... leads to breaking in the different ifunc-variants of the mentioned functions.
Thanks.
