2010-04-20Reapply the removal of SelectionDAGISel's BB, with a fix for the caseDan Gohman
where multiple blocks are emitted; functions which do this need to return the new BB so that their callers can stay current. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101843 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Revert 101825, which is causing trouble.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101832 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-19Eliminate SelectionDAGISel's "current block" member. Just pass it asDan Gohman
an argument to things that need it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101825 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
2010-04-19Give SelectionDAG a TargetMachine too, rather than having itDan Gohman
fetch one from the MachineFunction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101807 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
2010-04-17Use 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

2010-04-07Three 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

2010-04-05trim some spurious references to DwarfWriter. SDIsel really doesn'tChris Lattner
need it anymore, so don't addRequire it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100400 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-02stop using DebugLoc::getUnknownLoc()Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100215 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-02Switch the code generator (except the JIT) onto the new DebugLocChris Lattner
representation. This eliminates the 'DILocation' MDNodes for file/line/col tuples from -O0 -g codegen. This remove the old DebugLoc class, making it a typedef for DebugLoc, I'll rename NewDebugLoc next. I didn't update the JIT to use the new apis, so it will continue to work, but be as slow as before. Someone should eventually do this or, better yet, rip out the JIT debug info stuff and build the JIT on top of MC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100209 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-28finally remove the immAllOnesV_bc/immAllZerosV_bc patternsChris Lattner
and those derived from them. These are obnoxious because they were written as: PatLeaf<(bitconvert). Not having an argument was foiling adding better type checking for operand count matching up with what was required (in this case, bitconvert always requires an operand!) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99759 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-28now that (parallel) is gone and a variety of bugs in targetsChris Lattner
are cleaned up, we can remove an old fixme. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99741 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-28add an optimized form of OPC_EmitMergeInputChains for the 1, 0 and Chris Lattner
1, 1 cases which are by-far the most frequent. This shrinks the X86 isel table from 77014 -> 74657 bytes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99740 91177308-0d34-0410-b5e6-96231b3b80d8

scope due to obviously false predicate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99723 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-25Change tblgen to emit FOOISD opcode names as twoChris Lattner
bytes instead of one byte. This is important because we're running up to too many opcodes to fit in a byte and it is aggrevated by FIRST_TARGET_MEMORY_OPCODE making the numbering sparse. This just bites the bullet and bloats out the table. In practice, this increases the size of the x86 isel table from 74.5K to 76K. I think we'll cope :) This fixes rdar://7791648 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@99494 91177308-0d34-0410-b5e6-96231b3b80d8
