LLInt C loop

I'm fighting with LLInt C loop too. I generated the 
LLIntAssembly.h manually and then tried to build JSC.

I had to fix the following opcodes, because GCC suggested parenthesis:
- OFFLINE_ASM_OPCODE_LABEL(op_pre_inc)
- OFFLINE_ASM_OPCODE_LABEL(op_pre_dec)
- OFFLINE_ASM_OPCODE_LABEL(op_post_inc)
- OFFLINE_ASM_OPCODE_LABEL(op_post_dec)
- OFFLINE_ASM_OPCODE_LABEL(op_add)
- OFFLINE_ASM_OPCODE_LABEL(op_sub)

SIGN_BIT32(b-a) --> SIGN_BIT32((b-a))
SIGN_BIT32(b+a) --> SIGN_BIT32((b+a))

I assume it can be fixed in the original code somewhere.

But the bigger problem is the following error messege:
/home/oszi/WebKit/Source/JavaScriptCore/llint/LLIntAssembly.h:125: error: ‘assert’ was not declared in this scope

Have you got any ide what can be the problem and how can we fix it?
