Module E_ACSL.Smart_stmt

Create a statement from a statement kind.

Create a block statement from a block to replace a given statement. Requires that (1) the block is not empty, or (2) the statement is a skip.

Create a block statement from a block

Create a block statement from a statement list.

assigns ~loc ~result value creates a statement to assign the value expression to the result lval.

assigns_field ~loc vi field value creates a statement to assign the value expression to the field of the structure in the variable vi.

if ~loc ~cond ~then_blk ~else_blk creates an if statement with cond as condition and then_blk and else_blk as respectively "then" block and "else" block.

Create a break statement

struct_local_init ~loc vi fields creates a local initialization for the structure variable vi. fields is a list of couple (name, e) where name is the name of a field in the structure and e is the expression to initialize that field.

Construct a call to a function with the given name.

• raises Not_found

  if the given string does not represent a function in the AST, for instance if the function does not exist.

Construct a call to a library function with the given name.

prefix defaults to the E-ACSL RTL API prefix and can be explicitely provided to call functions without this prefix.

• raises Rtl.Symbols.Unregistered

  if the given string does not represent such a function or if library functions were never registered (only possible when using E-ACSL through its API).

Construct a call to __e_acsl_store_block that observes the allocation of the given varinfo. See share/e-acsl/e_acsl.h for details about this function.

Same as store_stmt for __e_acsl_duplicate_store_block that first checks for a previous allocation of the given varinfo.

Same as store_stmt for __e_acsl_delete_block that observes the de-allocation of the given varinfo. If is_addr is false (default), take the address of varinfo.

Same as store_stmt for __e_acsl_full_init that observes the initialization of the given varinfo. The varinfo is the address to fully initialize, no addrOf is taken.

Same as store_stmt for __e_acsl_initialize that observes the initialization of the given left-value.

Same as store_stmt for __e_acsl_markreadonly that observes the read-onlyness of the given varinfo.
