2009-07-01CommuteChangesDestination() should check if to-be-commuted instruction ↵Evan Cheng
defines any register. Also teaches the default commuteInstruction() to commute instruction without definitions (e.g. X86::test / ARM::tsp). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74602 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-01Remove special handling of implicit_def. Fix a couple more bugs in ↵Evan Cheng
liveintervalanalysis and coalescer handling of implicit_def. Note, isUndef marker must be placed even on implicit_def def operand or else the scavenger will not ignore it. This is necessary because -O0 path does not use liveintervalanalysis, it treats implicit_def just like any other def. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74601 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-01Handle IMPLICIT_DEF with isUndef operand marker, part 2. This patch moves ↵Evan Cheng
the code to annotate machineoperands to LiveIntervalAnalysis. It also add markers for implicit_def that define physical registers. The rest, is just a lot of details. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74580 91177308-0d34-0410-b5e6-96231b3b80d8
2009-07-01Remove unused AsmPrinter OptLevel argument, and propogate.Daniel Dunbar
- This more or less amounts to a revert of r65379. I'm curious to know what happened that caused this variable to become unused. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74579 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Add an "alignment" field to the MachineFunction object. It makes more sense toBill Wendling
have the alignment be calculated up front, and have the back-ends obey whatever alignment is decided upon. This allows for future work that would allow for precise no-op placement and the like. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74564 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Temporarily restore the scavenger implicit_def checking code. MachineOperand ↵Evan Cheng
isUndef mark is not being put on implicit_def of physical registers (created for parameter passing, etc.). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74519 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Add a bit IsUndef to MachineOperand. This indicates the def / use register ↵Evan Cheng
operand is defined by an implicit_def. That means it can def / use any register and passes (e.g. register scavenger) can feel free to ignore them. The register allocator, when it allocates a register to a virtual register defined by an implicit_def, can allocate any physical register without worrying about overlapping live ranges. It should mark all of operands of the said virtual register so later passes will do the right thing. This is not the best solution. But it should be a lot less fragile to having the scavenger try to track what is defined by implicit_def. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74518 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-26fix a really subtle bug in the cross section of aliases and TLS:Chris Lattner
the SelectionDAG::getGlobalAddress function properly looks through aliases to determine thread-localness, but then passes the GV* down to GlobalAddressSDNode::GlobalAddressSDNode which does not. Instead of passing down isTarget, just pass down the predetermined node opcode. This fixes some assertions with out of tree changes I'm working on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74325 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-24This increases the maximum for MVT::LAST_VALUETYPEDavid Greene
This change doubles the allowable value for MVT::LAST_VALUETYPE. It does this by doing several things. 1. Introduces MVT::MAX_ALLOWED_LAST_VALUETYPE which in this change has a value of 64. This value contains the current maximum for the MVT::LAST_VALUETYPE. 2. Instead of checking "MVT::LAST_VALUETYPE <= 32", all of those uses now become "MVT::LAST_VALUETYPE <= MVT::MAX_ALLOWED_LAST_VALUETYPE" 3. Changes the dimension of the ValueTypeActions from 2 elements to four elements and adds comments ahead of the declaration indicating the it is "(MVT::MAX_ALLOWED_LAST_VALUETYPE/32) * 2". This at least lets us find what is affected if and when MVT::MAX_ALLOWED_LAST_VALUETYPE gets changed. 4. Adds initializers for the new elements of ValueTypeActions. This does NOT add any types in MVT. That would be done separately. This doubles the size of ValueTypeActions from 64 bits to 128 bits and gives us the freedom to add more types for AVX. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@74110 91177308-0d34-0410-b5e6-96231b3b80d8
