Let us at least try it outside of toy examples.
If anybody has std.regex.ctRegex usage I'd be curious to see:
1. Build time w/o -cache=mmap
2. First build time w -cache=mmap
3. Subsequent build times w -cache=mmap
P.S. It's a crude PoC. I think we can do better.
Another caveat: Posix-only for now.
Did a few cleanups and widened the scope a bit.
So here is what happens in my benchmark for std.regex.
-O -inline -release:
88s --> 80s, memory use ~700Mb -> ~400Mb
19s -> 12.8s
Experimental std.regex.v2 is sadly broken by a recent change to
It would be very interesting to check as it eats up to 17Gb of
