* Disallow YIELD and other allocated nop hints in pre-ARMv6 architectures.Richard Barton2012-05-021-7/+0

* Thumb parsing and encoding support for NOP.Jim Grosbach2011-08-191-1/+1
| | | | | | | The irony is not lost that this is not a completely trivial patchset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138143 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix predicates for Thumb co-processor instructions.Jim Grosbach2011-07-131-15/+0
| | | | | | | They're all Thumb2 only, not just some of them. More refactoring cleanup coming. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135081 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix encoding and add parsing support for the arm/thumb CPS instruction:Bruno Cardoso Lopes2011-02-141-0/+3
| | | | | | | | | | | | | | - Add custom operand matching for imod and iflags. - Rename SplitMnemonicAndCC to SplitMnemonic since it splits more than CC from mnemonic. - While adding ".w" as an operand, don't change "Head" to avoid passing the wrong mnemonic to ParseOperand. - Add asm parser tests. - Add disassembler tests just to make sure it can catch all cps versions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125489 91177308-0d34-0410-b5e6-96231b3b80d8

* Add parsing for the Thumb t_addrmode_s4 addressing mode. This can almostBill Wendling2010-11-301-0/+3

* Add MC encodings for some Thumb instructions. Test for a few of them. The "bxBill Wendling2010-11-191-0/+8
lr" instruction cannot be tested just yet. It requires matching a "condition code", but adding one of those makes things go south quickly... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119774 91177308-0d34-0410-b5e6-96231b3b80d8
