2010-05-01Don't pass SDValues by non-const reference unless they may beDan Gohman
modified. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102816 91177308-0d34-0410-b5e6-96231b3b80d8
2010-05-01Reorgnaize more switch code lowering to clean up some trickyDan Gohman
code, and to eliminate the need for the SelectionDAGBuilder state to be live during CodeGenAndEmitDAG calls. Call SDB->clear() before CodeGenAndEmitDAG calls instead of before it, and move the CurDAG->clear() out of SelectionDAGBuilder, which doesn't own the DAG, and into CodeGenAndEmitDAG. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102814 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-27Revert a small part of 102372; this fixes at least oneDale Johannesen
of the dbg testsuite regressions. I don't think this is really the right fix; this change exposed an existing problem upstream somewhere. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102410 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-26Add DBG_VALUE handling for byval parameters; thisDale Johannesen
produces a comment on targets that support it, but the Dwarf writer is not hooked up yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102372 91177308-0d34-0410-b5e6-96231b3b80d8

into SelectionDAGBuilder itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102128 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-22Move HandlePHINodesInSuccessorBlocks functions out of SelectionDAGISelDan Gohman
and into SelectionDAGBuilder and FastISel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102123 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-22Move PHINodesToUpdate out of SelectionDAGBuilder and intoDan Gohman
FunctionLoweringInfo, as it isn't SelectionDAG-specific. This isn't completely natural, as PHI node state is not per-function but rather per-basic-block, however there's currently no other convenient per-basic-block state to group it with. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@102109 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-21Move several SelectionDAG-independent utility functions out of theDan Gohman
SelectionDAG directory and into a new Analysis.cpp file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101975 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Sink the CopyToExportRegsIfNeeded calls out of SelectionDAGISelDan Gohman
into SelectionDAGBuilder. This avoids a separate pass over the instructions, and has the side effect of providing debug location information to the copy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101906 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Don't send PHI nodes down to SelectionDAGBuilder of FastISel, sinceDan Gohman
they end up doing nothing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101904 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-20Sink DebugLoc handling out of SelectionDAGISel into FastISel andDan Gohman
SelectionDAGBuilder, where it doesn't have to be as complicated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101848 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Eliminate the CurMBB member from SelectionDAGBuilder. For places thatDan Gohman
need it, just pass around the parent block of the current instruction explicitly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101822 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Code that needs a TargetMachine should have access to one directly, ratherDan Gohman
than just getting one through a TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101802 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-17Delete now-unnecessary const_casts.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101637 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Use const qualifiers with TargetLowering. This eliminates severalDan Gohman
const_casts, and it reinforces the design of the Target classes being immutable. SelectionDAGISel::IsLegalToFold is now a static member function, because PIC16 uses it in an unconventional way. There is more room for API cleanup here. And PIC16's AsmPrinter no longer uses TargetLowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101635 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-16Revert 101465, it broke internal OpenGL testing.Eric Christopher
Probably the best way to know that all getOperand() calls have been handled is to replace that API instead of updating. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101579 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-14Pull utility routines with no SelectionDAG dependence out ofDan Gohman
SelectionDAGBuilder. FunctionLoweringInfo isn't an ideal place for them to live, but it's better than SelectionDAGBuilder for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101267 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-08convert a report_fatal_error that I was able to trigger into a nice errorChris Lattner
so the user at least knows what inline asm is a problem. For example: error: inline asm not supported yet: don't know how to handle tied indirect register inputs pr8788-1.c:14:10: note: generated from here asm ("\n" : "+r" (stack->regs) ^ Instead of: fatal error: error in backend: Don't know how to handle tied indirect register inputs yet! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100731 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-07Three changes:Chris Lattner
1. Introduce some enums and accessors in the InlineAsm class that eliminate a ton of magic numbers when handling inline asm SDNode. 2. Add a new MDNodeSDNode selection dag node type that holds a MDNode (shocking!) 3. Add a new argument to ISD::INLINEASM nodes that hold !srcloc metadata, propagating it to the instruction emitter, which drops it. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100605 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-04Reapply address space patch after fixing an issue in MemCopyOptimizer.Mon P Wang
Added support for address spaces and added a isVolatile field to memcpy, memmove, and memset, e.g., llvm.memcpy.i32(i8*, i8*, i32, i32) -> llvm.memcpy.p0i8.p0i8.i32(i8*, i8*, i32, i32, i1) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100304 91177308-0d34-0410-b5e6-96231b3b80d8
