cmplei
cmplei
compare less than or equal signed immediate
Operation: if ((signed) rA < (signed) IMMED)
then rB
←
1
else rB
←
0
Assembler Syntax:
cmplei rB, rA, IMMED
Example:
cmplei r6, r7, 100
Description: Sign-extends the immediate value IMMED to 32 bits and compares it to the value of
rA. If rA <= σ(IMMED), then
cmplei stores 1 to rB; otherwise stores 0 to rB.
Usage:
cmplei performs the signed <= operation of the C programming language. The
maximum allowed value of IMMED is 32766. The minimum allowed value is –32769.
Pseudoinstruction:
cmplei is implemented using a cmplti instruction with an immediate value
IMMED + 1.
