It's time for the new version to get tested!
C:\>zxb --version
zxb 1.4.0-s1779
(using my benchmark suite listed above)
The good: It all compiles and runs. And runs very very slightly faster. We're into much less than a frame (Only visible with more iterations).
The bad: One test (fsin) actually went slower than previously. And we're still about double the time of zip2 compiler for integer results - as discussed above. Zip2 is actually producing that pretty awful code posted in the last few posts, but it's still twice as fast as ZXB for simple integer maths. I suspect the asm modules are mostly untouched - meaning that most of the code the new version produces is identical. It's how it's getting there that's changed!
