* ARM assembly parsing for MOV (register).Jim Grosbach2011-07-193-19/+46
| | | | | | | | | Correct the handling of the 's' suffix when parsing ARM mode. It's only a truly separate opcode in Thumb. Add test cases to make sure we handle the s and condition suffices correctly, including diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135513 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM assembly parsing for MOV (immediate).Jim Grosbach2011-07-197-21/+99
| | | | | | | | | Add range checking for the immediate operand and handle the "mov" mnemonic choosing between encodings based on the value of the immediate. Add tests for fixups, encoding choice and values, and diagnostic for out of range values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135500 91177308-0d34-0410-b5e6-96231b3b80d8
