2011-08-09PTX: Add initial support for device function callsJustin Holewinski
- Calls are supported on SM 2.0+ for function with no return values git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137125 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Move CalculateRegClass to MRI::recomputeRegClass.Jakob Stoklund Olesen
This function doesn't have anything to do with spill weights, and MRI already has functions for manipulating the register class of a virtual register. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137123 91177308-0d34-0410-b5e6-96231b3b80d8

instead of a vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137099 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-09Remove an instance where the 'unwind' instruction was created.Bill Wendling
The 'unwind' instruction was acting essentially as a placeholder, because it would be replaced at the end of this function by a branch to the "unwind handler". The 'unwind' instruction is going away, so use 'unreachable' instead, which serves the same purpose as a placeholder. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137098 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-08Don't clobber pending ST regs when FP regs are killed.Jakob Stoklund Olesen
X86FloatingPoint keeps track of pending ST registers for an upcoming inline asm instruction with fixed stack register constraints. It does this by remembering which FP register holds the value that should appear at a fixed stack position for the inline asm. When that FP register is killed before the inline asm, make sure to duplicate it to a scratch register, so the ST register still has a live FP reference. This could happen when the same FP register was copied to two ST registers, or when a spill instruction is inserted between the ST copy and the inline asm. This fixes PR10602. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137050 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-05Reject RS_Spill ranges from local splitting as well.Jakob Stoklund Olesen
All new local ranges are marked as RS_New now, so there is no need to attempt splitting of RS_Spill ranges any more. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137002 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-05Only mark remainder intervals as RS_Spill after per-block splitting.Jakob Stoklund Olesen
The local ranges created get to stay in the RS_New stage, just like for local and region splitting. This gives tryLocalSplit a bit more freedom the first time it sees one of these new local ranges. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137001 91177308-0d34-0410-b5e6-96231b3b80d8

2011-08-05Delete getMultiUseBlocks and splitSingleBlocks.Jakob Stoklund Olesen
These functions are no longer used, and they are easily replaced with a loop calling shouldSplitSingleBlock and splitSingleBlock. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136993 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-05Also use shouldSplitSingleBlock() in the fallback splitting mode.Jakob Stoklund Olesen
Drop the use of SplitAnalysis::getMultiUseBlocks, there is no need to go through a SmallPtrSet any more. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136992 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-05Split around single instructions to enable register class inflation.Jakob Stoklund Olesen
Normally, we don't create a live range for a single instruction in a basic block, the spiller does that anyway. However, when splitting a live range that belongs to a proper register sub-class, inserting these extra COPY instructions completely remove the constraints from the remainder interval, and it may be allocated from the larger super-class. The spiller will mop up these small live ranges if we end up spilling anyway. It calls them snippets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136989 91177308-0d34-0410-b5e6-96231b3b80d8
