// RUN: llvm-mc -triple thumbv7 -show-encoding < %s | FileCheck %s
// Test each of the Thumb1 data-processing instructions
// The assembly syntax for these instructions allows an optional Rd register

// - Rd == Rn
// - Rd, Rn and Rm are < r8
// In addition, some operations are commutative, allowing the transormation

// - Rd == Rn || Rd == Rm
// - Rd, Rn and Rm are < r8
