2010-05-14Fast ISel trivially coalesces away no-op casts, so check for this whenDan Gohman
setting kill flags. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103832 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-14Don't set kill flags for instructions which the scheduler has cloned.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103827 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-14Rename "HasCalls" in MachineFrameInfo to "AdjustsStack" to better describe whatBill Wendling
the variable actually tracks. N.B., several back-ends are using "HasCalls" as being synonymous for something that adjusts the stack. This isn't 100% correct and should be looked into. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103802 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-13Implement a correct ui64->f32 conversion. The oldDale Johannesen
one was subject to double rounding in extreme cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103744 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-13An Instruction has a trivial kill only if its use is in the sameDan Gohman
basic block. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103725 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-11Add initial kill flag support to FastISel.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103529 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-11Don't set kill flags on uses of CopyFromReg nodes. InstrEmitter doesn'tDan Gohman
create separate virtual registers for CopyFromReg values, so uses of them don't necessarily kill the value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103519 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-11I got tired of VISIBILITY_HIDDEN colliding with the gcc enum. Rename itDuncan Sands
to LLVM_LIBRARY_VISIBILITY and introduce LLVM_GLOBAL_VISIBILITY, which is the opposite, for future use by dragonegg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103495 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-11Trim #includes and forward declarations.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103489 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-11Implement a bunch more TargetSelectionDAGInfo infrastructure.Dan Gohman
Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and EmitTargetCodeForMemmove out of TargetLowering and into SelectionDAGInfo to exercise this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103481 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-10Be careful with operand promotion. For a binary operation, the source ↵Evan Cheng
operands may be the same. PR7018. rdar://7939869. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103419 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-10Add an assertion to catch attempts to access off the end of the array.Duncan Sands
Based on a patch by Javier Martinez. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103391 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-07SDDbgValues are apparently not being legalized. Fix a symptom of the problem,Dan Gohman
and not the real problem itself, by dropping debug info for i128 values. rdar://7958162. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103310 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-07Fix PR 7087, and probably other things, by extendingDale Johannesen
getConstantFP to accept the two supported long double target types. This was not the original intent, but there are other places that assume this works and it's easy enough to do. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103299 91177308-0d34-0410-b5e6-96231b3b80d8

doesn't have to guess. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103194 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103139 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-05Add an "IsBottomUp" member function to FastISel, which will be used toDan Gohman
support a new bottom-up mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103138 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@103126 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-04Re-enable isel kill flags, now that the local allocator is ignoring them.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102981 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-03Factor out FastISel's code for materializing constants and other valuesDan Gohman
in registers into a separate function to de-couple it from the top-down-specific logic in getRegForValue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102975 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-01Insert ANY_EXTEND node instead of invalid truncate during DAG Combining (X & 1),Anton Korobeynikov
when needed. This fixes PR7001 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102838 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-01Remove the code for special-casing byval for fast-isel. SelectionDAGDan Gohman
handles argument lowering anyway, so there's no need for special casing here. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102828 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-01Re-disable kill flags, as there is more trouble.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102826 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-01Re-enable kill flags from SelectionDAGISel, with a fix: don'tDan Gohman
try to put a kill flag on a DBG_INFO instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102820 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-01Don't pass SDValues by non-const reference unless they may beDan Gohman
modified. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102816 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-01Reorgnaize more switch code lowering to clean up some trickyDan Gohman
code, and to eliminate the need for the SelectionDAGBuilder state to be live during CodeGenAndEmitDAG calls. Call SDB->clear() before CodeGenAndEmitDAG calls instead of before it, and move the CurDAG->clear() out of SelectionDAGBuilder, which doesn't own the DAG, and into CodeGenAndEmitDAG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102814 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-01Get rid of the EdgeMapping map. Instead, just check for BasicBlockDan Gohman
changes before doing phi lowering for switches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102809 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-30EXTRACT_VECTOR_ELT of an INSERT_VECTOR_ELT may have the same index, but theBill Wendling
indexes could be of a different value type. Or not even using the same SDNode for the constant (weird, I know). Compare the actual values instead of the pointers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102791 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-30Remove this debug output. The MachineFunction will be printed once all ofDan Gohman
instruction selection is done; it's confusing to see parts of it printed, while other parts are omitted, along the way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102771 91177308-0d34-0410-b5e6-96231b3b80d8

easy cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102678 91177308-0d34-0410-b5e6-96231b3b80d8
