Top-level analysis

analyseAST :: MonadTrav m => CTranslUnit -> m GlobalDecls #

Analyse the given AST

analyseAST ast results in global declaration dictionaries. If you want to perform specific actions on declarations or definitions, you may provide callbacks in the MonadTrav m.

Returns the set of global declarations and definitions which where successfully translated. It is the users responsibility to check whether any hard errors occurred (runTrav does this for you).

analyseExt :: MonadTrav m => CExtDecl -> m () #

Analyse an top-level declaration

analyseFunDef :: MonadTrav m => CFunDef -> m () #

Analyse a function definition

analyseDecl :: MonadTrav m => Bool -> CDecl -> m () #

Analyse a declaration other than a function definition

Note: static assertions are not analysed

tStmt :: MonadTrav m => [StmtCtx] -> CStat -> m Type #

Typecheck a statement, given a statement context. The type of a statement is usually void, but expression statements and blocks can sometimes have other types.
