From 5d5b657f606b5939062983b1f90c3359d542672e Mon Sep 17 00:00:00 2001 From: Li Jin Date: Mon, 26 Jan 2026 06:38:38 +0000 Subject: Fixed compiler improvements and added comprehensive test suite - Fixed makefile preprocessor macro definitions (removed spaces in -D flags) - Added null pointer check in compiler class declaration handling - Added comprehensive test specifications for various language features: - attrib, backcall, cond, config, existential, export, goto - import, literals, macro, metatable, operators, return - string, switch, vararg, with Co-Authored-By: Claude Sonnet 4.5
