[RISC-V manual: bgeu](https://docs.riscv.org/reference/isa/v20260120/unpriv/rv32.html#norm:bge_bgeu_op)

## Forms

- `bleu t1, t2, label`
  - `bleu t1,t2,label` → `bgeu t2, t1, label`

## Operands

- `t1`: Any integer register, `x0` to `x31`, or its named alias, such as `zero`, `t0` or `t6`.
- `t2`: An integer register. It may be the same register as `t1`.
- `label`: A named address in the program, such as the start of a loop or a variable in `.data`.

## Example

```riscv
# First bleu case is taken; second is not. t2 ends at 11 (10 + 1).
.text
li t2, 0
li t0, 3
li t1, 7
bleu t0, t1, taken
addi t2, t2, 1
j first_done # Skip the other marker unconditionally.
taken:
addi t2, t2, 10
first_done:
li t0, 7
li t1, 3
bleu t0, t1, missed
addi t2, t2, 1
j second_done # Skip the other marker unconditionally.
missed:
addi t2, t2, 10
second_done:
# t2=11 proves one taken and one untaken path.
