IERoutineContext

Build an IR-CFG from a list of statements. The first statement is the input statement. Note that the resulting CFG may not contain all provided IR statements; only reachable IR statements are present. The resulting CFG is gap-less.

Build an IR-CFG using the provided list of statements, and set the resulting CFG as the default one for this converted routine. The current conversion lists will be used.

Initialize a state to emulate this routine. The variables map is uninitialized.

Conversion FROM IR offset TO native address.

Conversion FROM native address to IR offset. The IR offset is an int, but returned as a long to conveniently manipulate it with IInstruction.

Create a copy variable for a pair of variable.

Not all variables can be copied. Currently, copies are limited to registers variables.

Create a truncated copy of a variable.

Not all variables can be copied. Currently, copies are limited to registers variables.

Create the copy of a variable.

Not all variables can be copied. Currently, copies are limited to registers variables.

Create a composition.

Create a composition.

Create a conversion operation: an integer truncation, integer extension (zero or signed), float truncation or extension, float-to-int and int-to-float conversion.

Create a resize operation operation: truncation, zero-extension, or sign-extension.

Retrieve or create a stack reference, ie a pointer to stack-memory variable.

Create or retrieve a special routine-scope variable. The variable id is in the [SPECIAL, SPECIAL_END] range.

Clients should avoid using this method. Non-stack routine-scope variables created by third-party code should generally be in the VIRTUAL range. See the createVirtualVar(String, int) method.

Create or retrieve a virtual routine-scope variable. The variable id is in the [VIRTUAL, VIRTUAL_END] range.

Get the set of all variables that are copies or partial copies of the provided input id. The input id may be of a copy variable itself, in which case, this method is equivalent as retrieving the copies of its source.

The copies returned is a list of vars entirely contained in the input var.

Get the set of all variables making use of the provided variable.

The copies returned is a list of vars whose overlap with the input var is non-null.

Retrieve a piece of transient data.

Retrieve the list of duplicates (mirror, secondary dups) associated to a register.

Retrieve the list of memory variables used by this context: stack variables and global variables.

Convenience method.

Convenience method.

Convenience method.

Retrieve or create the mirror - that is, the first full copy, in the [IDL_MIRROR, IDL_MIRROR_END[ range - of the provided register.

Note: A register EVar is global and non-typeable. A mirror EVar is local and typeable.

Retrieve the IR expressions holding the routine's parameters. May be used only after a decompilation has fully completed.

Retrieve the manager for local EVars representing physical stack variables (in the general sense, ie memory slots).

Convenience method.

Convenience method.

Retrieve a stack reference, ie a pointer to stack-memory variable.

Retrieve the stack variable at the provided offset.

Retrieve the list of memory stack variables used by this context.

Retrieve all defined stack variables whose (starting) offset are included in the provided range. Note that the last variable may span outside the range.

Retrieve the raw list of converted IR-statements. Beware: this list gets stale very quickly, as the decompiler deals with and optimizes an IR-CFG (initially built from this list), instead.
