2010-11-04In the calling convention logic, ValVT is always a legal type,Duncan Sands
and as such can be represented by an MVT - the more complicated EVT is not needed. Use MVT for ValVT everywhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118245 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-03Covert VORRIMM to be produced via early target-specific DAG combining, ↵Owen Anderson
rather than legalization. This is both the conceptually correct place for it, as well as allowing it to be more aggressive. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118204 91177308-0d34-0410-b5e6-96231b3b80d8

We could be more aggressive about making this work for a larger range of constants, but this seems like a good start. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118201 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-03Unlike a lot of NEON instructions, vext isn't _actually_ parameterized by ↵Owen Anderson
element size. Instead, all of the different element sizes are pseudo instructions that map down to vext.8 underneath, with the immediate shifted left to reflect the increased element size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118183 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-03Check for extractelement with a variable operand for the element number.Bob Wilson
For NEON we had been assuming this was always an immediate constant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118175 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03Simplify uses of MVT and EVT. An MVT can be compared directlyDuncan Sands
with a SimpleValueType, while an EVT supports equality and inequality comparisons with SimpleValueType. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118169 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03Inside the calling convention logic LocVT is always a simpleDuncan Sands
value type, so there is no point in passing it around using an EVT. Use the simpler MVT everywhere. Rather than trying to propagate this information maximally in all the code that using the calling convention stuff, I chose to do a mainly low impact change instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118167 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-03The MC code couldn't handle ARM LDR instructions with negative offsets:Bill Wendling
vldr.64 d1, [r0, #-32] The problem was with how the addressing mode 5 encodes the offsets. This change makes sure that the way offsets are handled in addressing mode 5 is consistent throughout the MC code. It involves re-refactoring the "getAddrModeImmOpValue" method into an "Imm12" and "addressing mode 5" version. But not to worry! The majority of the duplicated code has been unified. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118144 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-03Two sets of changes. Sorry they are intermingled.Evan Cheng
1. Fix pre-ra scheduler so it doesn't try to push instructions above calls to "optimize for latency". Call instructions don't have the right latency and this is more likely to use introduce spills. 2. Fix if-converter cost function. For ARM, it should use instruction latencies, not # of micro-ops since multi-latency instructions is completely executed even when the predicate is false. Also, some instruction will be "slower" when they are predicated due to the register def becoming implicit input. rdar://8598427 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118135 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-02Completely reject instructions that have an operand in theirChris Lattner
ins/outs list that isn't specified by their asmstring. Previously the asmmatcher would just force a 0 register into it, which clearly isn't right. Mark a bunch of ARM instructions that use this as isCodeGenOnly. Some of them are clearly pseudo instructions (like t2TBB) others use a weird hasExtraSrcRegAllocReq thing that will either need to be removed or the asmmatcher will need to be taught about it (someday). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118119 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-02Since these fields are not exactly equivalent to the encoded field, rename ↵Owen Anderson
them to something with semantic meaning. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118097 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-02Rename getAddrModeImm12OpValue to getAddrModeImmOpValue and expand it to workBill Wendling
with immediates up to 16-bits in size. The same logic is applied to other LDR encodings, e.g. VLDR, but which use a different immediate bit width (8-bits in VLDR's case). Removing the "12" allows it to be more generic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118094 91177308-0d34-0410-b5e6-96231b3b80d8
