      Delete valgrind magic in pss-test. · 870ede28
      Niels Möller authored
      * testsuite/pss-test.c: Delete magic to let valgrind to check if
      pss_encode_mgf1 is side-channel silent with respect to the salt
      and digest inputs. It turns out that the most significant bits of
      the padded bignum, and hence its size, depends on these inputs.
      Which results in a data-dependent branch in the normalization code
      of at the end of gmp's mpz_import.
