Bug Fixes

Fix: Library modules broken after decompile/recompile

Library modules (lib_*.xvmc) use flags: 0x1 to register their functions as globals so other scripts can call them. This flag was silently dropped during decompilation, causing recompiled library modules to stop working — any script depending on them would fail at runtime.

29 out of 842 game scripts are affected (all lib_*.xvmc files).

The decompiler now emits #! flags: 0x1 automatically, and the compiler preserves it through to the output .xvmc.

Fix: Missing trailing ret 0 sentinel

The compiler omitted the trailing ret 0 when a function's last statement was already a return. This caused the decompiler's CFG builder to lose if blocks whose jump targets pointed past the last instruction.

Fix: break statement and structural analysis

• Added break statement support inside while loops
• Fixed while-loop exit block causing post-loop code to be absorbed into the loop body
• Fixed elif chains breaking when the merge point coincided with an outer loop exit

Fix: stitem stack order

The decompiler and compiler had the wrong pop/push order for index store operations (obj[idx] = val), producing invalid code for scripts using indexed assignment.

New Directive: #! flags:

The #! flags: directive is emitted automatically by the decompiler for library modules. It is not gated by --hashes because it affects runtime behavior.

Value	Meaning	Files in game
0x0	Standard script	813
0x1	Library module	29

Known Differences (non-functional)

Round-tripped files may differ from originals in constant ordering, StringBuffer layout, max_stack values (precise vs over-estimated), and omission of dead-code jmp instructions after ret. All differences are functionally equivalent.
