* Move PHINodesToUpdate out of SelectionDAGBuilder and intoDan Gohman2010-04-221-5/+5
| | | | | | | | | 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. llvm-svn: 102109
* Move several SelectionDAG-independent utility functions out of theDan Gohman2010-04-211-0/+1

* Sink the CopyToExportRegsIfNeeded calls out of SelectionDAGISelDan Gohman2010-04-201-0/+3
| | | | | | | | into SelectionDAGBuilder. This avoids a separate pass over the instructions, and has the side effect of providing debug location information to the copy. llvm-svn: 101906

| | | | | | | | | | | | | 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. llvm-svn: 101635

* Three changes:Chris Lattner2010-04-071-39/+45
| | | | | | | | | | | | | | | 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. llvm-svn: 100605

* Reapply address space patch after fixing an issue in MemCopyOptimizer.Mon P Wang2010-04-041-5/+27
| | | | | | | 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) llvm-svn: 100304

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. llvm-svn: 100209

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | placement should be determined by the relative order of incoming llvm instructions. The scheduler will now use the SDNode ordering information to determine where to insert them. A dbg_value instruction is inserted after the instruction with the last highest source order and before the instruction with the next highest source order. It will optimize the placement by inserting right after the instruction that produces the value if they have consecutive order numbers. Here is a theoretical example that illustrates why the placement is important. tmp1 = store tmp1 -> x ... tmp2 = add ... ... call ... store tmp2 -> x Now mem2reg comes along: tmp1 = dbg_value (tmp1 -> x) ... tmp2 = add ... ... call ... dbg_value (tmp2 -> x) When the debugger examine the value of x after the add instruction but before the call, it should have the value of tmp1. Furthermore, for dbg_value's that reference constants, they should not be emitted at the beginning of the block (since they do not have "producers"). This patch also cleans up how SDISel manages DbgValue nodes. It allow a SDNode to be referenced by multiple SDDbgValue nodes. When a SDNode is deleted, it uses the information to find the SDDbgValues and invalidate them. They are not deleted until the corresponding SelectionDAG is destroyed. llvm-svn: 99469
* Fix pr6543: svn r88806 changed MachineJumpTableInfo::getJumpTableIndex() toBob Wilson2010-03-181-3/+2
| | | | | | | | | | | | | | | | | always create a new jump table. The intention was to avoid merging jump tables in SelectionDAGBuilder, and to wait for the branch folding pass to merge tables. Unfortunately, the same getJumpTableIndex() method is also used to merge tables in branch folding, so as a result of this change branch tables are never merged. Worse, the branch folding code is expecting getJumpTableIndex to always return the index of an existing table, but with this change, it never does so. In at least some cases, e.g., pr6543, this creates references to non-existent tables. I've fixed the problem by adding a new createJumpTableIndex function, which will always create a new table, and I've changed getJumpTableIndex to only look at existing tables. llvm-svn: 98845
