2010-02-26Move dbg_value generation to target-independent FastISel,Dale Johannesen
as X86 is currently the only FastISel target. Per review. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97255 91177308-0d34-0410-b5e6-96231b3b80d8

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
2010-02-06After Victor's latest commits I am seeing nullDale Johannesen
addresses in dbg.declare; ignore this for the moment to prevent things from breaking. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@95471 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-18Enable code to emit dbg.declare as DEBUG_VALUEDale Johannesen
comments (fast isel, X86). This doesn't seem to break any functionality, but will introduce cases where -g affects the generated code. I'll be fixing that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93811 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-15Improve llvm.dbg.declare intrinsic by referring directly to the storage in ↵Victor Hernandez
its first argument, via function-local metadata (instead of via a bitcast). This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare. It also strips old llvm.dbg.declare intrinsics that did not pass metadata as the first argument. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93531 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-05Don't use the ISD::NodeType enum for SDNode opcodes, as CodeGenDan Gohman

2009-12-29remove a bunch of unneeded functions.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@92263 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

2009-10-14I don't see any point in having both eh.selector.i32 and eh.selector.i64,Duncan Sands
so get rid of eh.selector.i64 and rename eh.selector.i32 to eh.selector. Likewise for eh.typeid.for. This aligns us with gcc, which always uses a 32 bit value for the selector on all platforms. My understanding is that the register allocator used to assert if the selector intrinsic size didn't match the pointer size, and this was the reason for introducing the two variants. However my testing shows that this is no longer the case (I fixed some bugs in selector lowering yesterday, and some more today in the fastisel path; these might have caused the original problems). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@84106 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-09Extract scope information from the variable itself, instead of relying on ↵Devang Patel
alloca or llvm.dbg.declare location. While recording beginning of a function, use scope info from the first location entry instead of just relying on first location entry itself. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83684 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-07Fix a thinko: When lowering fneg with xor, bitcast the operandsDan Gohman
from floating-point to integer first, and bitcast the result back to floating-point. Previously, this test was passing by falling back to SelectionDAG lowering. The resulting code isn't as nice, but it's correct and CodeGen now stays on the fast path. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@81171 91177308-0d34-0410-b5e6-96231b3b80d8
