8.5.32. cmplei

Instruction compare less than or equal signed immediate

if ((signed) rA < (signed) IMMED)

then rB ←  1

else rB ←  0

Assembler Syntax

cmplei rB, rA, IMMED


cmplei 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 cmplei stores 1 to rB; otherwise stores 0 to rB.


cmplei performs the signed <= operation of the C programming language. The maximum allowed value of IMMED is 32766. The minimum allowed value is –32769.


cmplei is implemented using a cmplti instruction with an IMM16 immediate value of IMMED + 1.
