The ARM instruction ldrsh fails to assemble, when an offset is added after loading from a register:

ldrsh r3,[r0],2   ; expected: F2 30 D0 E0
ldrsh r3,[r0],-2  ; expected: F2 30 50 E0
ldrsh r3,[r0],r2  ; expected: F2 30 90 E0
                  ; instead: "ldrsh-test.asm(5) error: ARM parameter failure"

The error occurs on any target ARM architecture (.gba .arm, .nds, or .3ds)

I've tested other closely related instructions, and they are successfully assembled:

ldrh r3,[r0],2    ; output: B2 30 D0 E0
ldrsb r3,[r0],2   ; output: D2 30 D0 E0
ldrsh r3,[r0,2]   ; output: F2 30 D0 E1

The text was updated successfully, but these errors were encountered:
