* ARM: Mark double-precision instructions as suchTim Northover2013-10-24
| | | | | | | | | | | | This prevents us from silently accepting invalid instructions on (for example) Cortex-M4 with just single-precision VFP support. No tests for the extra Pat Requires because they're essentially assertions: the affected code should have been lowered to libcalls before ISel. rdar://problem/15302004 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193354 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM: use TableGen patterns to select CMOV operations.Tim Northover2013-08-22
| | | | | | | | | | | | Back in the mists of time (2008), it seems TableGen couldn't handle the patterns necessary to match ARM's CMOV node that we convert select operations to, so we wrote a lot of fairly hairy C++ to do it for us. TableGen can deal with it now: there were a few minor differences to CodeGen (see tests), but nothing obviously worse that I could see, so we should probably address anything that *does* come up in a localised manner. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188995 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | This adds a new class for non-predicable NEON instructions and a new DecoderNamespace for v8 NEON instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186504 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | instructions. This adds a new decoder table/namespace 'VFPV8', as these instructions have their top 4 bits as 0b1111, while other Thumb instructions have 0b1110. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185642 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: fix more cases where predication may or may not be allowedTim Northover2013-06-26
| | | | | | | | | | Unfortunately this addresses two issues (by the time I'd disentangled the logic it wasn't worth putting it back to half-broken): + Coprocessor instructions should all be predicable in Thumb mode. + BKPT should never be predicable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@184965 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: add fstmx and fldmx instructions for assemblyTim Northover2013-05-31
| | | | | | | | | These instructions are deprecated oddities, but we still need to be able to disassemble (and reassemble) them if and when they're encountered. Patch by Amaury de la Vieuville. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183011 91177308-0d34-0410-b5e6-96231b3b80d8
