Member Function Documentation

◆ install()

ARM64Exception::Result ARM64Exception::install	(	ARM64Exception::ExceptionType	vector,
		ARM64Exception::Handler	handler
	)

Install an exception handler.

Parameters

vector	Exception vector to install
handler	Exception handler function to install.

Returns: Result code

Field Documentation

◆ m_vecTable

Address ARM64Exception::m_vecTable

private

ARM64 exception vector jump table.

The ARM64 processor will start executing at the appropriate vector offset in the jump table and perform a jump to the exception handler address, which it retrieves from the exception handlers table.
