2010-03-27Thumb2 storeFrom/LoadToStackSlot() need to handle tGPR regs directly, not passJim Grosbach
through to the generic version. The generic functions use STR/LDR, but T2 needs the t2STR/t2LDR instead so we get the addressing mode correct. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99678 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-26Remove the duplicate multiclass N3VSh_QHSD and use N3VInt_QHSD which is modifiedJohnny Chen
to now take a format argument. N3VDInt<> and N3VQInt<> are modified to take a format argument as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99676 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-26If we mark clean-ups as clean-ups, then it could break when inlining through anBill Wendling
'invoke' instruction. You will get a situation like this: bb: %ehptr = eh.exception() %sel = eh.selector(%ehptr, @per, 0); ... bb2: invoke _Unwind_Resume_or_Rethrow(%ehptr) %normal unwind to %lpad lpad: ... The unwinder will see the %sel call as a clean-up and, if it doesn't have a catch further up the call stack, it will skip running it. But there *is* another catch up the stack -- the catch for the %lpad. However, we can't see that. This is fixed in code-gen, where we detect this situation, and convert the "clean-up" selector call into a "catch-all" selector call. This gives us the correct semantics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99671 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-26Add NVExtFrm to represent NEON Vector Extract Instructions, that uses Inst{11-8}Johnny Chen

2010-03-26Add N3RegVShFrm to represent 3-Register Vector Shift Instructions, which do notJohnny Chen
follow the N3RegFrm's operand order of D:Vd N:Vn M:Vm. The operand order of N3RegVShFrm is D:Vd M:Vm N:Vn (notice that M:Vm is the first src operand). Add a parent class N3Vf which requires passing a Format argument and which the N3V class is modified to inherit from. N3V class represents the "normal" 3-Register NEON Instructions with N3RegFrm. Also add a multiclass N3VSh_QHSD to represent clusters of NEON 3-Register Shift Instructions and replace 8 invocations with it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99655 91177308-0d34-0410-b5e6-96231b3b80d8

dispatch to the appropriate routines to handle the different interpretations of the shift amount encoded in the imm6 field. The Vd, Vm fields are interpreted the same between the two, though. See, for example, A8.6.367 VQSHL, VQSHLU (immediate) for N2RegVShLFrm format and A8.6.368 VQSHRN, VQSHRUN for N2RegVShRFrm format. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99590 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25MC: Stop restarting layout on every relaxation.Daniel Dunbar

I am a little surprised we make more than 2 relaxation passes.

2010-03-25Add a late SSEDomainFix pass that twiddles SSE instructions to avoid domain ↵Jakob Stoklund Olesen
crossings. On Nehalem and newer CPUs there is a 2 cycle latency penalty on using a register in a different domain than where it was defined. Some instructions have equvivalents for different domains, like por/orps/orpd. The SSEDomainFix pass tries to minimize the number of domain crossings by changing between equvivalent opcodes where possible. This is a work in progress, in particular the pass doesn't do anything yet. SSE instructions are tagged with their execution domain in TableGen using the last two bits of TSFlags. Note that not all instructions are tagged correctly. Life just isn't that simple. The SSE execution domain issue is very similar to the ARM NEON/VFP pipeline issue handled by NEONMoveFixPass. This pass may become target independent to handle both. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99524 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-25Change tblgen to emit FOOISD opcode names as twoChris Lattner
bytes instead of one byte. This is important because we're running up to too many opcodes to fit in a byte and it is aggrevated by FIRST_TARGET_MEMORY_OPCODE making the numbering sparse. This just bites the bullet and bloats out the table. In practice, this increases the size of the x86 isel table from 74.5K to 76K. I think we'll cope :) This fixes rdar://7791648 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99494 91177308-0d34-0410-b5e6-96231b3b80d8
