; Show that we know how to translate mov (shifted register), which
; are pseudo instructions for ASR, LSR, ROR, and RRX.

; NOTE: We use -O2 to get rid of memory stores.

; REQUIRES: allow_dump

; Compile using standalone assembler.
; RUN: %p2i --filetype=asm -i %s --target=arm32 --args -O2 \
; RUN:   | FileCheck %s --check-prefix=ASM

; Show bytes in assembled standalone code.
; RUN: %p2i --filetype=asm -i %s --target=arm32 --assemble --disassemble \
; RUN:   --args -O2 | FileCheck %s --check-prefix=DIS

; Compile using integrated assembler.
; RUN: %p2i --filetype=iasm -i %s --target=arm32 --args -O2 \
; RUN:   | FileCheck %s --check-prefix=IASM

; Show bytes in assembled integrated code.
