v0.7.2

  • x86: a vector path for double rsqrt (AVX2 and FMA; the SSE2 entry point goes through it), CORE-MATH's fast path transcribed; lanes it cannot decide go to cr_rsqrt. 2.6 times faster than CORE-MATH's scalar rsqrt on a Zen 3. Checked by rsqrt-vcheck, in make check, on CORE-MATH's hard cases at every scale, with a control that must fail.
  • CORE-MATH: powf.c and sin.c from master fe94e92, so all 165 of CORE-MATH's files are byte-identical to its master again. No changed result was found (sin: 2^26 large arguments and 1,975,928 hard cases; powf: 2.7 billion pairs; four rounding modes).
  • Build: mpfrcheck and pownf-search need MPFR 4.2; with an older MPFR they are left out instead of stopping the build.
  • crtest: CRTEST_LOG2N sets the random sample size of verify64 (and verify64e).
  • crmvec-run: --help and --version (asked for by conda-forge's review, as a test of the installed package); with no arguments it prints the usage and exits 2.
