void CommaRT::raise	(	SRFrame *	frame,
		const ExceptionDecl *	exception,
		llvm::Value *	fileName,
		llvm::Value *	lineNum,
		llvm::Value *	message = `0`,
		llvm::Value *	length = `0`
	)

Throws an exception.

Calls registerException on the provided exception declaration, then generates code for a raise. fileName is an i8* yeilding the name of the file or module the exception is raised in and lineNum is the corresponding line number. message is a Comma vector (one dimension) of type String and length is its length (an i32). The supplied vector may be null.

Note:: For compiler generated exceptions it is always preferable to raise using a static global as the runtime can avoid a copy of the message data in that case.

Definition at line 345 of file CommaRT.cpp.

void CommaRT::raise	(	SRFrame *	frame,
		const ExceptionDecl *	exception,
		llvm::Value *	fileName,
		llvm::Value *	lineNum,
		llvm::GlobalVariable *	message = `0`
	)

Throws an exception.

Calls registerException on the provided exception declaration, then generates code for a raise. fileName is an i8* yeilding the name of the file or module the exception is raised in and lineNum is the corresponding line number. message must be a pointer to a global string of type i8* or null.

		llvm::Value *	fileName,
		llvm::Value *	lineNum,

llvm::GlobalVariable * CommaRT::registerCapsule ( Domoid * domoid )

Definition at line 293 of file CommaRT.cpp.

llvm::Constant * CommaRT::registerException ( const ExceptionDecl * exception )

Registers and exception with the runtime.

Given an ExceptionDecl AST node, this method returns an opaque global representing the exception. The first call made to this method with a given ExceptionDecl as argument registers the exception in the system and associates a global as representation. Subsequent calls using the same declaration node return the same global.

Definition at line 439 of file CommaRT.cpp.

void CommaRT::reraise	(	SRFrame *	frame,
		llvm::Value *	exception
	)

Reraises the given exception object.

Definition at line 396 of file CommaRT.cpp.

void CommaRT::unhandledException	(	llvm::IRBuilder<> &	builder,
		llvm::Value *	exception
	)			const

Generates a call to _comma_unhandled_exception. This is only called by the main routine when an exception has unwound the entire stack. Its only argument is the unhandled exception object.

A call to _comma_unhandled_exception does not return.

Definition at line 312 of file CommaRT.cpp.

llvm::Value * CommaRT::vstack	(	llvm::IRBuilder<> &	builder,
		const llvm::Type *	ptrTy
	)			const

Returns a pointer to the most recent data pushed onto the variable stack cast to the given type.

Definition at line 503 of file CommaRT.cpp.

void CommaRT::vstack_alloc	(	llvm::IRBuilder<> &	builder,
		llvm::Value *	size
	)			const

Allocates size bytes of uninitialized data onto the vstack (accessable thru vstack()).

void CommaRT::vstack_pop ( llvm::IRBuilder<> & builder ) const

Pops the last item pushed from the variable stack.

Definition at line 498 of file CommaRT.cpp.

void CommaRT::vstack_push	(	llvm::IRBuilder<> &	builder,
		llvm::Value *	data,
		llvm::Value *	size
	)			const

Pushes size bytes from data onto the variable stack.
