Detailed Description

Pre-analysis step.

It transforms the raw intermediate representation removing var_decl duplication: two var_decls with the same variable name in the same function.

Definition at line 65 of file var_decl_fix.hpp.

Constructor & Destructor Documentation

◆ VarDeclFix()

VarDeclFix::VarDeclFix	(	const application_managerRef	AppM,

	)

Constructor.

Parameters

AppM	is the application manager
fun_id	is the function index
design_flow_manager	is the design flow manager
parameters	is the set of input parameters
frontend_flow_step_type	is the type of step; it is different for subclasses
