Python scripts generate the following files
helper_protos_generated.h.inc
For each instruction we create DEF_HELPER function prototype
helper_funcs_generated.c.inc
For each instruction we create the helper function definition
tcg_funcs_generated.c.inc
For each instruction we create TCG code to generate call to helper
tcg_func_table_generated.c.inc
Table of function pointers indexed by opcode
shortcode_generated.h.inc
Generate a table of instruction "shortcode" semantics
opcodes_def_generated.h.inc
Gives a list of all the opcodes
op_attribs_generated.h.inc
Lists all the attributes associated with each instruction
op_regs_generated.h.inc
Lists the register and immediate operands for each instruction
printinsn_generated.h.inc
Data for printing (disassembling) each instruction (format
string + operands)
