Limitations as a whole:

• Link against -lgc if you want garbage collection

Limitations on the parser:

• None known

Limitations on the JIT engine:

• All states receive exactly one page of buffer, which is not bounds-checked
• I am too lazy to write an executable memory allocator
• Code is suboptimal in places

Limitations on the macro assembler:

• R12 and R13 are not usable as a base register of a location
• Special cases in encoding which is not handled
• Unlinked jumps will be NOPs if executed prior to linkage
• No bounds checking on assembler buffer
