Sami Vaarala	1875b54225	Perf test fixes and additions - Add missing 't = 0' initializer to test-assign-addto. Without the initializer 't' becomes NaN and for some reason is over 20x slower on x86 as a result of that. If 't' is initialized performance on x86 is fine. (It's worth investigating why falling out of the fastint fast path is so costly on x86 but not on x64; NaN normalization?) - Add missing test-assign-reg.pl. - Add specific addition tests, where numbers involved are (a) fastints, (b) doubles, (c) NaNs. These tests demonstrate the roughly 10x difference on x86 for NaNs and other IEEE doubles -- with and without packed duk_tval.	9 years ago

Perf test fixes and additions

- Add missing 't = 0' initializer to test-assign-addto.  Without the
  initializer 't' becomes NaN and for some reason is over 20x slower
  on x86 as a result of that.  If 't' is initialized performance on x86
  is fine.  (It's worth investigating why falling out of the fastint
  fast path is so costly on x86 but not on x64; NaN normalization?)

- Add missing test-assign-reg.pl.

- Add specific addition tests, where numbers involved are (a) fastints,
  (b) doubles, (c) NaNs.  These tests demonstrate the roughly 10x
  difference on x86 for NaNs and other IEEE doubles -- with and without
  packed duk_tval.
