* Include `windows.h` rather than `Windows.h` to make things compile on MinGW. * Custom implementation of timegm/os.time for all platforms * Disable builtin constant folding when getfenv/setfenv are used * Fixes https://github.com/Roblox/luau/issues/1042 * Fixes https://github.com/Roblox/luau/issues/1043 New Type Checker * Initial work toward type states. * Rework most overloadable operators to use type families. * Initial work toward our new nonstrict mode. Native Codegen * Fix native code generation for dead loops * Annotate top-level functions as cold * Slightly smaller/faster x64 Luau calls * emitInstCall used to not set savedpc itself, but now it does for consistency with all other implementations * Implement cmov support for X64 * Fix assertion in luau-compile when module is empty * Optimize A64 calls at some code size cost * Inline constant array index offset into the load/store instruction * Increase x64 spill slots from 5 to 13 --------- Co-authored-by: Arseny Kapoulkine <arseny.kapoulkine@gmail.com> Co-authored-by: Vyacheslav Egorov <vegorov@roblox.com> Co-authored-by: Lily Brown <lbrown@roblox.com> Co-authored-by: Aaron Weiss <aaronweiss@roblox.com> Co-authored-by: Alexander McCord <amccord@roblox.com>
