Capping a value
Clamping is a compare and a conditional skip. Say a function floors its argument at ten — anything below becomes ten:
cmp r0, #0x9
bgt .L3
mov r0, #0xa
bx lr
It compares against #0x9, and when the value is already greater (bgt) it skips straight to the return. Otherwise it moves the floor #0xa into place and returns that. A ceiling clamp is the mirror image: the comparison value and the branch condition flip, and the constant moved in is the upper limit instead.
Read the target's cmp and the constant it moves to recover the bound.
Your task
Write clampTop, taking an int x, to reproduce the target assembly.
