Hi to the AARCH64 team,
I managed to do a (bog-standard normal) bootstrap on my Aarch64 system.
See: https://gcc.gnu.org/pipermail/gcc-testresults/2024-January/805347.html
It got this for the libgo tests:
=== libgo tests ===
Running target unix
FAIL: math/cmplx
=== libgo Summary ===
# of expected passes 195
# of unexpected failures 1
/dev/shm/bld2283/./gcc/gccgo version 14.0.1 20240114 (experimental)
[master r14-7229-ged5bf2080c5] (GCC)
Subsequently, I ran LAPACK's test programs (using lapack-3.11.0) with
optimization options -O3 -march=native -mtune=native, and I got the
following differences with respect to the same run using gfortran 13 as
installed on Debian testing (updated last Saturday):

Note that the only differences are in COMPLEX16 (i.e., complex
computations using 64 bit REAL and IMAGINARY parts).
Perhaps the failing libgo test case is sufficient to track this down ...
I suppose you can reproduce that one more easily.
Kind regards,
