BLT, BGE, BLTU, BGEU

blt  rs1, rs2, label   # signed <
bge  rs1, rs2, label   # signed >=
bltu rs1, rs2, label   # unsigned <
bgeu rs1, rs2, label   # unsigned >=

Greater-than and less-or-equal forms are assembler aliases that reverse operands.

x86 connection: roughly replaces cmp plus jl/jge or jb/jae. Signedness is explicit in the branch mnemonic, not inferred from shared flags.
