Check_vector_size checks if the size of the vector fits in the size reserved for it. This check creates problems in the Clang assembler. A new macro, end_vector_entry, is added and check_vector_size is deprecated. This new macro fills the current exception vector until the next exception vector. If the size of the current vector is bigger than 32 instructions then it gives an error. Change-Id: Ie8545cf1003a1e31656a1018dd6b4c28a4eaf671 Signed-off-by: Roberto Vargas <roberto.vargas@arm.com>
