Hi,
There is a lot of code involved in the whole translation:
The guest instructions are not directly translated to the host
assembly but they are first translated in some intermediate OPs
(named TCG).
This translation takes place here:
void gen_intermediate_code(CPUARMState *env, TranslationBlock *tb)
In target/arm/translate.c
