Function Documentation

◆ add_pragma_disable_assigns_check() [1/3]

goto_programt& add_pragma_disable_assigns_check ( goto_programt prog)

Adds pragmas on all instructions in a GOTO program to disable inclusion checking on them.

Parameters
progA mutable reference to the GOTO program.
Returns
The same reference after mutation (i.e., adding the pragmas).

Definition at line 85 of file instrument_spec_assigns.cpp.

◆ add_pragma_disable_assigns_check() [2/3]

goto_programt::instructiont& add_pragma_disable_assigns_check ( goto_programt::instructiont instr)

Adds a pragma on a GOTO instruction to disable inclusion checking.

Parameters
instrA mutable reference to the GOTO instruction.
Returns
The same reference after mutation (i.e., adding the pragma).

Definition at line 79 of file instrument_spec_assigns.cpp.

◆ add_pragma_disable_assigns_check() [3/3]

void add_pragma_disable_assigns_check ( source_locationt source_location)

Adds a pragma on a source_locationt to disable inclusion checking.

Definition at line 73 of file instrument_spec_assigns.cpp.

◆ add_pragma_disable_pointer_checks()

void add_pragma_disable_pointer_checks ( source_locationt source_location)

Adds a pragma on a source location disable all pointer checks.

The disabled checks are: "pointer-check", "pointer-primitive-check", "pointer-overflow-check", "signed-overflow-check",

Definition at line 54 of file instrument_spec_assigns.cpp.

◆ add_propagate_static_local_pragma()

void add_propagate_static_local_pragma ( source_locationt source_location)

Sets a pragma to mark assignments to static local variables that need to be propagated upwards in the search.

Definition at line 45 of file instrument_spec_assigns.cpp.

◆ has_propagate_static_local_pragma()

bool has_propagate_static_local_pragma ( source_locationt source_location)

True iff the pragma to mark assignments to static local variables that need to be propagated upwards in the search is set.
