2009-10-13More Neon clean-up: avoid the need for custom-lowering vld/st-lane intrinsicsBob Wilson
by creating TargetConstants during instruction selection instead of during legalization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84042 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-13NEON VLD/VST are now fully implemented. For operations that expand toBob Wilson
multiple instructions, the expansion is done during selection so there is no need to do anything special during legalization. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84036 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-07Add PseudoSourceValues for constpool stuff on ELF (Darwin should use ↵Anton Korobeynikov
something similar) and register spills. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83435 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-23ARM does not support offset folding (yet). Disable it for now.Anton Korobeynikov
This fixes PR5031. Unfortunately, there is no small testcase :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82643 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-19Fix PR4926. When target hook EmitInstrWithCustomInserter() insert new basic ↵Evan Cheng
blocks and update CFG, it should also inform sdisel of the changes so the phi source operands will come from the right basic blocks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82311 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-18Enhance EmitInstrWithCustomInserter() so target can specify CFG changes that ↵Evan Cheng
sdisel will use to properly complete phi nodes. Not functionality change yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@82273 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-15Expand all v2f64 arithmetic operations for Neon.Bob Wilson
Radar 7200803. (This should also fix the SingleSource/UnitTests/Vector/sumarray-dbl test.) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81959 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-01Clean up LSDA name generation and use for SJLJ exception handling. ThisJim Grosbach
makes an eggregious hack somewhat more palatable. Bringing the LSDA forward and making it a GV available for reference would be even better, but is beyond the scope of what I'm looking to solve at this point. Objective C++ code could generate function names that broke the previous scheme. This fixes that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80649 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-28Let Darwin linker auto-synthesize stubs and lazy-pointers. This deletes a ↵Evan Cheng

2009-08-27Transform float scalar_to_vector into subreg accesses.Anton Korobeynikov
No idea whether this is profitable or not. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80245 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-26Remove unneeded ARM-specific DAG nodes for VLD* and VST* Neon operations.Bob Wilson
The instructions can be selected directly from the intrinsics. We will need to add some ARM-specific nodes for VLD/VST of 3 and 4 128-bit vectors, but those are not yet implemented. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80117 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-22Make x86 test actually test x86 code generation. Fix the Eli Friedman
construct on ARM, which was breaking by coincidence, and add a similar testcase for ARM. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79719 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-19Add support for Neon VEXT (vector extract) shuffles.Bob Wilson
This is derived from a patch by Anton Korzh. I modified it to recognize the VEXT shuffles during legalization and lower them to a target-specific DAG node. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79428 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-15Change allowsUnalignedMemoryAccesses to take type argument since some targetsEvan Cheng
support unaligned mem access only for certain types. (Should it be size instead?) ARM v7 supports unaligned access for i16 and i32, some v6 variants support it as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79127 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-14Allow targets to specify their choice of calling conventions perAnton Korobeynikov
libcall. Take advantage of this in the ARM backend to rectify broken choice of CC when hard float is in effect. PIC16 may want to see if it could be of use in MakePIC16Libcall, which works unchanged. Patch by Sandeep! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79033 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-14Now that all the legal Neon shuffles (or at least the ones that have beenBob Wilson
implemented so far) are recognized during legalization, it is easy to fall back to the default expansion for other shuffles. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78995 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-14Create a new ARM-specific DAG node, VDUP, to represent a splat from aBob Wilson
scalar_to_vector. Generate these VDUP nodes during legalization instead of trying to recognize the pattern during selection. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78994 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-14During legalization, change Neon vdup_lane operations from shuffles toBob Wilson
target-specific VDUPLANE nodes. This allows the subreg handling for the quad-register version to be done easily with Pats in the .td file, instead of with custom code in ARMISelDAGToDAG.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78993 91177308-0d34-0410-b5e6-96231b3b80d8
