[Qemu-devel] gen_op* function definitions

[Qemu-devel] gen_op* function definitions

[Ryan W Smith]

I'm trying to figure out how the translation blocks are generated and  
I'm having a bit of difficulty.  I'm trying to find and modify a  
particular instruction rep ins*, which I've found and it looks like  
it's being broken down into simpler instructions in the translation  
process.  I've followed it all the way down to the most basic  
instructions, the first of which is gen_op_movl_A0_reg[EDI](), which  
translates to gen_op_movl_A0_EDI().  This is where I'm stuck, I can't  
find the definition for this function, or any of the gen_op*  
instructions for that matter anywhere in the qemu source.  I must be  
missing something, can someone point me in the right direction to  
find the definitions for the gen_op* functions.

Thanks,
Ryan

op.c is compiled and the resulting object file op.o is processed by
dyngen program, producing gen-op.h, opc.h, and op.h. These define the
gen_op* versions of the functions, originally op_something in op.c.
