3.5.9.2 Operation
These instructions test the value in a register against Operand2. They update the condition flags based
on the result, but do not write the result to a register.
The TST instruction performs a bitwise AND operation on the value in Rn and the value of Operand2.
This is the same as the ANDS instruction, except that it discards the result.
To test whether a bit of Rn is 0 or 1, use the TST instruction with an Operand2 constant that has that
bit set to 1 and all other bits cleared to 0.
The TEQ instruction performs a bitwise Exclusive OR operation on the value in Rn and the value of
Operand2
. This is the same as the EORS instruction, except that it discards the result.
Use the TEQ instruction to test if two values are equal without affecting the V or C flags.
TEQ
is also useful for testing the sign of a value. After the comparison, the N flag is the logical Exclusive
OR of the sign bits of the two operands.
3.5.9.3 Restrictions
Do not use SP and do not use PC.
3.5.9.4 Condition flags
These instructions:
update the N and Z flags according to the result
can update the C flag during the calculation of Operand2, see Section 3.3.3 (p. 38)
do not affect the V flag.
3.5.9.5 Examples
TST
R0, #0x3F8
; Perform bitwise AND of R0 value to 0x3F8,
; APSR is updated but result is discarded
TEQEQ
R10, R9
; Conditionally test if value in R10 is equal to
; value in R9, APSR is updated but result is discarded
