Add instructions of SBC and SBRN opcode format. Signed-off-by: Bastian Koppelmann <kbastian@mail.uni-paderborn.de> --- v1 -> v2: - Change compare to 0 at instructions JZ_T and JNZ_T. - Group SBC instructions to one case. - Group SBRN instructions to one case. target-tricore/translate.c | 35 +++++++++++++++++++++++++++++++++++ 1 file changed, 35 insertions(+) -- 2.0.1
