Detailed Description
Helper class for processor modules to build macro instructions.
Member Function Documentation
◆ construct_macro()
|
inline |
Construct a macro instruction.
This function may be called from ana() to generate a macro instruction.
The real work is done by the 'build_macro()' virtual function. It must be defined by the processor module.
construct_macro() modifies the database using the info provided by build_macro(). It verifies if the instruction can really be created (for example, that other items do not hinder), may plan to reanalyze the macro, etc. If the macro instructions are disabled by the user, construct_macro() will destroy the macro instruction. Note: if INSN_MODMAC is not set in insn.flags, the database will not be modified.
- Parameters
-
insn the instruction to modify into a macro enable enable macro generation
- Return values
-
true the macro instruction is generated in 'insn' false did not create a macro
◆ build_macro()
|
pure virtual |
Try to extend the instruction.
- Parameters
-
insn Instruction to modify, usually the first instruction of the macro may_go_forward Is it ok to consider the next instruction for the macro? This argument may be false, for example, if there is a cross reference to the end of INSN. In this case creating a macro is not desired. However, it may still be useful to perform minor tweaks to the instruction using the information about the surrounding instructions.
- Returns
- true if created an macro instruction. This function may modify 'insn' and return false; these changes will be accepted by the kernel but the instruction will not be considered as a macro.
