2009-12-05Make TargetSelectInstruction protected and called from FastISel.cppDan Gohman
instead of SelectionDAGISel.cpp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90636 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-05Remove the target hook TargetInstrInfo::BlockHasNoFallThrough in favor ofDan Gohman
MachineBasicBlock::canFallThrough(), which is target-independent and more thorough. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90634 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-05The debug information for an LLVM Instruction applies to that InstructionDan Gohman
and that Instruction only. Implement this by setting the "current debug position" back to Unknown after processing each instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90632 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-05Fix this code to use DIScope instead of DICompileUnit, as in r90181.Dan Gohman
Don't print "SrcLine"; just print the filename and line number, which is obvious enough and more informative. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90631 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-05Don't print the debug directory; it's often long and uninteresting. OmitDan Gohman
the column number if it is not known. Handle the case of a missing filename better. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90630 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-04Add note about a subtle bug in this code. Does not effect the mainDuncan Sands

2009-12-04Also attempt trivial coalescing for live intervals that end in a copy.Jakob Stoklund Olesen
The coalescer is supposed to clean these up, but when setting up parameters for a function call, there may be copies to physregs. If the defining instruction has been LICM'ed far away, the coalescer won't touch it. The register allocation hint does not always work - when the register allocator is backtracking, it clears the hints. This patch takes care of a few more cases that r90163 missed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90502 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-03Fix ExpandShiftWithUnknownAmountBit, which was completely bogus.Duncan Sands
Pointed out by Javier Martinez (who also provided a patch). Since this logic is not used on (for example) x86, I guess nobody noticed. Tested by generating SHL, SRL, SRA on various choices of i64 for all possible shift amounts, and comparing with gcc. Since I did this on x86-32, I had to force the use of ExpandShiftWithUnknownAmountBit. What I'm saying here is that I don't have a testcase I can add to the repository. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90482 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-03Don't hang on to pointers or references after vector::push_back.Jakob Stoklund Olesen

2009-12-01Fix PR5391: support early clobber physical register def tied with a use (ewwww)Evan Cheng
- A valno should be set HasRedefByEC if there is an early clobber def in the middle of its live ranges. It should not be set if the def of the valno is defined by an early clobber. - If a physical register def is tied to an use and it's an early clobber, it just means the HasRedefByEC is set since it's still one continuous live range. - Add a couple of missing checks for HasRedefByEC in the coalescer. In general, it should not coalesce a vr with a physical register if the physical register has a early clobber def somewhere. This is overly conservative but that's the price for using such a nasty inline asm "feature". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90269 91177308-0d34-0410-b5e6-96231b3b80d8

2009-12-01Move PHIElimination::isLiveOut method to LiveVariables.Jakob Stoklund Olesen
We want LiveVariables clients to use methods rather than accessing the getVarInfo data structure directly. That way it will be possible to change the LiveVariables representation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90240 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-01Use CFG connectedness as a secondary sort key when deciding the order of ↵Jakob Stoklund Olesen
copy coalescing. This means that well connected blocks are copy coalesced before the less connected blocks. Connected blocks are more difficult to coalesce because intervals are more complicated, so handling them first gives a greater chance of success. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@90194 91177308-0d34-0410-b5e6-96231b3b80d8
