[Bug math/19590] Fail to build shared objects that use libmvec.so functions.


https://sourceware.org/bugzilla/show_bug.cgi?id=19590

--- Comment #2 from Andrew Senkevich <andrew.n.senkevich at gmail dot com> ---
Test case is:

-bash-4.2$ cat ./log.c
#include <math.h>

int N = 3000;
double a[3000];
double b[3000];

int test ()
{
  int i = 0;

#pragma omp simd
  for (i = 0; i < N; i++)
  {
    b[i] = log(a[i]);
  }

  return 0;
}

gcc ./log.c -O3 -fopenmp -ffast-math -I/INSTALL_PATH/include -fPIC -shared -o
./log.so -lm -L/INSTALL_PATH/lib/
will fail w/o fix.
Also with -mavx, -mavx2, -mavx512f for other vector variants.
