◆ generate_support_functions()

bool cpp_languaget::generate_support_functions ( symbol_table_baset symbol_table,
message_handlert message_handler 
)
overridevirtual

Create language-specific support functions, such as __CPROVER_start, __CPROVER_initialize and language-specific library functions.

This runs after the typecheck phase but before lazy function loading. Anything that must wait until lazy function loading is done can be deferred until final, which runs after lazy function loading is complete. Functions introduced here are visible to lazy loading and can influence its decisions (e.g. picking the types of input parameters and globals), whereas anything introduced during final cannot.
