Petri Häkkinen 298cd70154 Optimize vector literals by storing them in the constant table (#1096) ... With this optimization, built-in vector constructor calls with 3/4 arguments are detected by the compiler and turned into vector constants when the arguments are constant numbers. Requires optimization level 2 because built-ins are not folded otherwise by the compiler. Bytecode version is bumped because of the new constant type, but old bytecode versions can still be loaded. The following synthetic benchmark shows ~6.6x improvement. ``` local v for i = 1, 10000000 do v = vector(1, 2, 3) v = vector(1, 2, 3) v = vector(1, 2, 3) v = vector(1, 2, 3) v = vector(1, 2, 3) v = vector(1, 2, 3) v = vector(1, 2, 3) v = vector(1, 2, 3) v = vector(1, 2, 3) v = vector(1, 2, 3) end ``` Also tried a more real world scenario and could see a few percent improvement. Added a new fast flag LuauVectorLiterals for enabling the feature. --------- Co-authored-by: Petri Häkkinen <petrih@rmd.remedy.fi> Co-authored-by: vegorov-rbx <75688451+vegorov-rbx@users.noreply.github.com> Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com>		2023-11-17 04:54:32 -08:00
