2010-02-09move target-independent opcodes out of TargetInstrInfoChris Lattner
into TargetOpcodes.h. #include the new TargetOpcodes.h into MachineInstr. Add new inline accessors (like isPHI()) to MachineInstr, and start using them throughout the codebase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95687 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-23Remove the '-disable-scheduling' flag and replace it with the 'source' option ofBill Wendling
the '-pre-RA-sched' flag. It actually makes more sense to do it this way. Also, keep track of the SDNode ordering by default. Eventually, we would like to make this ordering a way to break a "tie" in the scheduler. However, doing that now breaks the "CodeGen/X86/abi-isel.ll" test for 32-bit Linux. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94308 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-19Add some new debugging APIs to print out "raw" SelectionDAGs to makeDavid Greene
understanding CannotYTetSelect and other errors easier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93901 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-15Add some debug routines to SelectionDAG to dump full DAGs.David Greene
print/dumpWithDepth allows one to dump a DAG up to N levels deep. dump/printWithFullDepth prints the whole DAG, subject to a depth limit on 100 in the default case (to prevent infinite recursion). Have CannotYetSelect to a dumpWithFullDepth so it is clearer exactly what the non-matching DAG looks like. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93538 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-06Teach dag combine to fold the following transformation more aggressively:Evan Cheng
(OP (trunc x), (trunc y)) -> (trunc (OP x, y)) Unfortunately this simple change causes dag combine to infinite looping. The problem is the shrink demanded ops optimization tend to canonicalize expressions in the opposite manner. That is badness. This patch disable those optimizations in dag combine but instead it is done as a late pass in sdisel. This also exposes some deficiencies in dag combine and x86 setcc / brcond lowering. Teach them to look pass ISD::TRUNCATE in various places. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92849 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-05Change SelectCode's argument from SDValue to SDNode *, to make it moreDan Gohman
clear what information these functions are actually using. This is also a micro-optimization, as passing a SDNode * around is simpler than passing a { SDNode *, int } by value or reference. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92564 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-29Final step in the metadata API restructuring: move the Chris Lattner
getMDKindID/getMDKindNames methods to LLVMContext (and add convenience methods to Module), eliminating MetadataContext. Move the state that it maintains out to LLVMContext. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92259 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-28This is a major cleanup of the instruction metadata interfaces thatChris Lattner
I asked Devang to do back on Sep 27. Instead of going through the MetadataContext class with methods like getMD() and getMDs(), just ask the instruction directly for its metadata with getMetadata() and getAllMetadata(). This includes a variety of other fixes and improvements: previously all Value*'s were bloated because the HasMetadata bit was thrown into value, adding a 9th bit to a byte. Now this is properly sunk down to the Instruction class (the only place where it makes sense) and it will be folded away somewhere soon. This also fixes some confusion in getMDs and its clients about whether the returned list is indexed by the MDID or densely packed. This is now returned sorted and densely packed and the comments make this clear. This introduces a number of fixme's which I'll follow up on. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92235 91177308-0d34-0410-b5e6-96231b3b80d8
