|
[PATCH 3/9] arm-asm: Support rotation for sxtb, sxth, uxtb, uxth
|
|
[PATCH 4/9] arm-asm: Warn if regset registers are not specified in ascending order
|
|
[PATCH 5/9] arm-asm: Add error case in asm_multiplication_opcode
|
|
[PATCH 6/9] arm-asm: Raise an error if asm_binary_opcode is used with PC as operand
|
|
[PATCH 7/9] arm-asm: Print a warning if asm_binary_opcode is used with SP as operand
|
|
[PATCH 8/9] arm-asm: Raise error if more than two operands are specified on mov, mvn, cmp, cmn, tst, teq
|
|
[PATCH 9/9] arm-asm: Raise error if asm_data_processing_opcode and asm_shift_opcode try to use PC for register-controlled shifts
