RISC-V bltz Pseudo-Instruction Details
Assembler pseudo-instructionbltz expands to blt rs, x0, offset. BLT branches when rs is less than x0 under signed comparison.
What You Write
bltz rs, offset
Typical Real Expansion
blt rs, x0, offset
What This Pseudo Instruction Is Saving You From Writing
A BLT spelling with x0 as the second operand.
How To Read The Expansion
Step 1
blt rs, x0, offset
Assembly Forms And Real Instructions
The expansion above identifies the BLT ISA semantics that apply.
Official References And Reading Order
This page treats pseudo-instructions as assembler-level aliases or macros: first read what real instructions they expand to, then use the official ISA manual for the behavior of those real instructions. ABI, relocation, and linker-relaxation details follow the psABI document.
Pitfalls / Common Confusions
BLT uses signed comparison; bltz supplies x0 as its second operand.
