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
-
prog A 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
-
instr A 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 & | 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.

Definition at line 45 of file instrument_spec_assigns.cpp.
◆ create_fresh_symbol()
|
static |
Creates a fresh symbolt with given suffix, scoped to the function of location.
