Description:
Usage:
Pseudo-instruction:
if ((signed) rA > (signed) IMMED)
then rB ← 1
else rB ← 0
cmpgti rB, rA, IMMED
cmpgti r6, r7, 100
Sign-extends the immediate value IMMED to 32 bits and compares it to the value of rA. If rA >
σ(IMMED), then cmpgti stores 1 to rB; otherwise stores 0 to rB.
cmpgti performs the signed > operation of the C programming language. The maximum
allowed value of IMMED is 32766. The minimum allowed value is –32769.
cmpgti is implemented using a cmpgei instruction with an IMM16 immediate value of
IMMED + 1.
compare greater than signed immediate
