2010-11-05Add FIXME.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118280 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-05When passing a parameter using the 'byval' mechanism, inline code needs to ↵Duncan Sands
be used to perform the copy, which may be of lots of memory [*]. It would be good if the fall-back code generated something reasonable, i.e. did the copy in a loop, rather than vast numbers of loads and stores. Add a note about this. Currently target specific code seems to always kick in so this is more of a theoretical issue rather than a practical one now that X86 has been fixed. [*] It's amazing how often people pass mega-byte long arrays by copy... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118275 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-05CrashRecoveryContext: Add RunSafelyOnThread helper function.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118272 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04When passing a huge parameter using the byval mechanism, a longDuncan Sands
sequence of loads and stores was being generated to perform the copy on the x86 targets if the parameter was less than 4 byte aligned, causing llc to use up vast amounts of memory and time. Use a "rep movs" form instead. PR7170. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118260 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118257 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04Add 118023 back, but with proper spelling for .uleb128/.sleb128.Rafael Espindola
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118254 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04Revert previous patch. Some targets don't support uleb and sayRafael Espindola
they do :-( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118250 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-04Introduce DIBuilder. It is intended to be a front-end friendly interface to ↵Devang Patel
emit debuggging information entries in LLVM IR. To create debugging information for a pointer, using DIBUilder front-end just needs DBuilder.CreatePointerType(Ty, Size); instead of DebugFactory.CreateDerivedType(llvm::dwarf::DW_TAG_pointer_type, TheCU, "", getOrCreateMainFile(), 0, Size, 0, 0, 0, OCTy); git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118248 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04Add getFile() to get DIFile of a DIType.Devang Patel

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
2010-11-04Fix @llvm.prefetch isel. Selecting between pld / pldw using the first ↵Evan Cheng
immediate rw. There is currently no intrinsic that matches to pli. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118237 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04partition operand processing between aliases and instructions.Chris Lattner
Right now the code is partitioned but the behavior is the same. This should be improved in the near future. This removes some uses of TheOperandList. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118232 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04pull name slicing out of BuildInstructionOperandReference soChris Lattner
it doesn't do any lexical stuff anymore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118230 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-04replace SrcOpNum with SrcOpName, eliminating a numering dependencyChris Lattner
on the incoming operand list. This also makes the code simpler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118225 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04System: Add llvm_execute_on_thread, which does what it says.Daniel Dunbar
- Primarily useful for running some code with a specified stack size, when pthreads are available. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118222 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04Add ARM fixup info for load/store label references. Probably will need a bit ofJim Grosbach
tweaking when we start using it for object file emission or JIT, but it's a start. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118221 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-04take a big step to making aliases more general and less of a hack:Chris Lattner
now matchables contain an explicit list of how to populate each operand in the result instruction instead of having them somehow magically be correlated to the input inst. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118217 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-04Disable fancy splitting during spilling unless -extra-spiller-splits is given.Jakob Stoklund Olesen
This way, InlineSpiller does the same amount of splitting as the standard spiller. Splitting should really be guided by the register allocator, and doesn't belong in the spiller at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118216 91177308-0d34-0410-b5e6-96231b3b80d8

CodeEmitter. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118209 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03Add rule to build MC'ized CodeEmitter.Jim Grosbach
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118207 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-03Support generating an MC'ized CodeEmitter directly. Maintain a reference to theJim Grosbach
Fixups list for the instruction so the operand encoders can add to it as needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118206 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
2010-11-03Add support for code generation of the one register with immediate form of vorr.Owen Anderson
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

2010-11-03Just return undef for invalid masks or elts, and since we're doing that,Eric Christopher
just do it earlier too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118195 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
2010-11-03This test assumes SSE is present; that is not the defaultDale Johannesen
on non-X86 hosts. Hopefully fixes ppc-host buildbot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118182 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
2010-11-03Rename FindExecutable to PrependMainExecutablePath.Mikhail Glushenkov
Makes it more clear that it is just a path manipulation function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118174 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-03Rename PointsToLocalMemory to PointsToLocalOrConstantMemory to makeDuncan Sands
the code more self-documenting. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118171 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

2010-11-03Fix preload instruction isel. Only v7 supports pli, and only v7 with mp ↵Evan Cheng
extension supports pldw. Add subtarget attribute to denote mp extension support and legalize illegal ones to nothing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@118160 91177308-0d34-0410-b5e6-96231b3b80d8
