I found time today to run some tests.
First of all, the result of the gcc test harness as applied to the top
of the complex/kvx branch in the https://github.com/kalray/gcc repository:
https://gcc.gnu.org/pipermail/gcc-testresults/2023-October/797627.html
I think there are several complex failures here that are not in
"standard" 12.2 release (for x86_64-linux-gnu).
I also compiled all of lapack-3.11.0 with that compiler and obtained the
same results as with gcc/gfortran 13.2:
