Current state CRASHES on load due to pre-alloc hooks with wrong calling
conventions. pushcclosure hook is still enabled with partially disabled
others. Needs all pre-alloc hooks disabled or CCs fixed before use.
Implemented:
- Full 5.1 tri-color incremental GC
- 5.1-style singlestep budget loop (replaces chunk-based approach)
- Per-step rdtsc timing (ZGCStats returns max_step_us, atomic_us)
- Configurable gcstepsize/gcstepmul/gcpause via ZGCTune()
- Pre-alloc GC hooks for 7 API functions (5.1 luaC_checkGC pattern)
- Stress test addon: /gclife, /gcsweep, /gccompare
Broken:
- Pre-alloc hooks have CC mismatches causing immediate crash on load
- pushfstring is cdecl variadic, not fastcall (removed)
- pushstring has ambiguous CC (removed, covered by pushlstring)
- pushcclosure hook still active -- may be causing the crash
- Half-initialized objects cause garbage gcptr under heavy stress
weirdperformance: re-enabled luagc.install() + luastr + luavm
