It seems OpenBLAS is to be blamed after all ...


>From kernel/arm64/dznrm2_thunderx2t99.c:


#define REGINF          "d9"

static void nrm2_compute(BLASLONG n, FLOAT *x, BLASLONG inc_x,
                         double *ssq, double *scale)
{

        __asm__ __volatile__ (
        "       fmov    "REGINF", x6


There is no mechanism to push/pop $d9 in the inline assembly :-(


If you concur, please close this issue and my apologies for the noise.
