Function Documentation

◆ is_nondet_initializable_static()

bool is_nondet_initializable_static ( const symbol_exprt symbol_expr,
const namespacet ns 
)

See the return.

Parameters
symbol_exprThe symbol expression to analyze.
nsNamespace for resolving type information
Returns
True if the symbol expression holds a static symbol which can be nondeterministically initialized, false otherwise.

Definition at line 36 of file nondet_static.cpp.

◆ nondet_static() [1/4]

void nondet_static ( const namespacet ns,
goto_functionst goto_functions 
)

Nondeterministically initializes global scope variables in CPROVER_initialize function.

Parameters
nsNamespace for resolving type information.
[out]goto_functionsExisting goto-functions to be updated.

Definition at line 129 of file nondet_static.cpp.

◆ nondet_static() [2/4]

static void nondet_static ( const namespacet ns,
goto_functionst goto_functions,
const irep_idt fct_name 
)
static

Nondeterministically initializes global scope variables in a goto-function.

Iterates over instructions in the specified function and replaces all values assigned to nondet-initializable static variables with nondeterministic values.

Parameters
nsNamespace for resolving type information.
[out]goto_functionsExisting goto-functions to be updated.
fct_nameName of the goto-function to be updated.

Definition at line 82 of file nondet_static.cpp.

◆ nondet_static() [3/4]

void nondet_static ( goto_modelt goto_model)

First main entry point of the module.

Nondeterministically initializes global scope variables, except for constants (such as string literals, final fields) and internal variables (such as CPROVER and symex variables, language specific internal variables).

Parameters
[out]goto_modelExisting goto-model to be updated.

Definition at line 139 of file nondet_static.cpp.

◆ nondet_static() [4/4]

void nondet_static ( goto_modelt goto_model,
const std::set< std::string > &  except_values 
)

Second main entry point of the module.

Nondeterministically initializes global scope variables, except for constants (such as string literals, final fields), internal variables (such as CPROVER and symex variables, language specific internal variables) and variables passed to except_value.

Parameters
[out]goto_modelExisting goto-model to be updated.
except_valueslist of symbol names that should not be updated.

Definition at line 151 of file nondet_static.cpp.

◆ nondet_static_matching()

void nondet_static_matching ( goto_modelt goto_model,
const std::string &  regex 
)

Nondeterministically initializes global scope variables that match the given regex.

Parameters
[out]goto_modelExisting goto-model to be updated.
regexregex for matching variables in the format "filename:variable" (same format as those of except_values in nondet_static(goto_model, except_values) variant above).
