Perf tests: const load, continue fast/slow, mandel
9 years ago
local function test()
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.
