Arseny Kapoulkine b1b21f395a Compiler: Optimize k*n and k+n when types are known (#1529) ... When type information is specified, we can compile k*n and k+n into MULK/ADDK forms that are faster to execute, as long as we think n is a number. Since we generally restrict type aware optimizations to O2, this does that as well. This makes trig benchmark ~4% faster on Apple M2 in VM, and also a tiny improvement on scimark (~0.1%) can be observed. The optimization only affects interpreted execution, as NCG already can synthesize optimal code here. If the type information is not truthful (e.g. user annotates type as a number and it's not), the worst case scenario is flipped arguments to metamethods like __add/__mul for constant left hand side. Fixes #626 (the fix requires type information or NCG but I doubt any further work on this is warranted) --------- Co-authored-by: vegorov-rbx <75688451+vegorov-rbx@users.noreply.github.com>		2024-11-19 07:42:44 -08:00
