* [ARMv8] Add CodeGen support for VSEL.Joey Gouly2013-08-221-8/+12
| | | | | | | | | This uses the ARMcmov pattern that Tim cleaned up in r188995. Thanks to Simon Tatham for his floating point help! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189024 91177308-0d34-0410-b5e6-96231b3b80d8
* ARM: use TableGen patterns to select CMOV operations.Tim Northover2013-08-221-9/+11
| | | | | | | | | | | | 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

* Split fpscr into two registers: FPSCR and FPSCR_NZCV.Lang Hames2012-03-061-5/+5
| | | | | | | | | | | The fpscr register contains both flags (set by FP operations/comparisons) and control bits. The control bits (FPSCR) should be reserved, since they're always available and needn't be defined before use. The flag bits (FPSCR_NZCV) should like to be unreserved so they can be hoisted by MachineCSE. This fixes PR12165. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@152076 91177308-0d34-0410-b5e6-96231b3b80d8
