2009-04-11Revert r68847. It breaks the build on non-Darwin targets, with this messageDan Gohman
from the assembler: Error: unknown pseudo-op: `.debug_inlined' git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68863 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-11Keep track of inlined functions and their locations. This information is ↵Devang Patel
collected when nested llvm.dbg.func.start intrinsics are seen. (Right now, inliner removes nested llvm.dbg.func.start intrinisics during inlining.) Create debug_inlined dwarf section using these information. This info is used by gdb, at least on Darwin, to enable better experience debugging inlined functions. See DwarfWriter.cpp for more information on structure of debug_inlined section. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68847 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-10DebugLabelFolder ruthlessly deletes redundant labels. However, sometimes the ↵Devang Patel
redundant labels is referenced by debug info somewhere else. This patch provies a way so that dwarf writer can mark labels as used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68813 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-10fix two problems with machine sinking:Chris Lattner
1. Sinking would crash when the first instruction of a block was sunk due to iterator problems. 2. Instructions could be sunk to their current block, causing an infinite loop. This fixes PR3968 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68787 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-10fix a broken assertion in ilist_iterator, which caused it to crash in theChris Lattner
bad case instead of actually assert. Bug pointed out by Jakob Stoklund Olesen! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68785 91177308-0d34-0410-b5e6-96231b3b80d8

real need for it to be short. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68742 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-09StringMap<DIE*>::iterator::first() returns a pointer to the first character ofBill Wendling
the key. This will cause it to create a new std::string, which isn't wanted. Instead, pass back the "const char*". Modify the EmitString() method to take a "const char*". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68741 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-09Fix pr3954. The register scavenger asserts for inline assembly withBob Wilson
register destinations that are tied to source operands. The TargetInstrDescr::findTiedToSrcOperand method silently fails for inline assembly. The existing MachineInstr::isRegReDefinedByTwoAddr was very close to doing what is needed, so this revision makes a few changes to that method and also renames it to isRegTiedToUseOperand (for consistency with the very similar isRegTiedToDefOperand and because it handles both two-address instructions and inline assembly with tied registers). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68714 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-09The way we are trying to figure out banksel immediate operand may yield ↵Sanjiv Gupta
different results for different type of insns. This will eventually need to be changed but currently let us prevent the crash in cases of incorrect detection of banksel operand. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68713 91177308-0d34-0410-b5e6-96231b3b80d8

attached testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68712 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-09Make sure to rebuild dependencies for the `check' and `unittests' targets soMisha Brukman
we're not testing out-of-date code. This also makes "make check" and "make unittests" work out-of-the box right after the configure step, without requiring the user to run "make tools-only" or "make libs-only". Tested on Linux/x86_64 and Darwin/x86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68708 91177308-0d34-0410-b5e6-96231b3b80d8

custom lowering an ADD to ADDC. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68671 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-09Generalize ExtendUsesToFormExtLoad to be usable for ANY_EXTEND,Dan Gohman
in addition to ZERO_EXTEND and SIGN_EXTEND. Fix a bug in the way it checked for live-out values, and simplify the way it find users by using SDNode::use_iterator's (relatively) new features. Also, make it slightly more permissive on targets with free truncates. In SelectionDAGBuild, avoid creating ANY_EXTEND nodes that are larger than necessary. If the target's SwitchAmountTy has enough bits, use it. This exposes the truncate to optimization early, enabling more optimizations. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68670 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-09Don't copy the operand of a SwitchInst into virtual registers asDan Gohman
eagerly. This helps avoid CopyToReg nodes in some cases where they aren't needed, and also helps subsequent optimizer heuristics in cases where the extra nodes would cause the node to appear to have multiple results. This doesn't have a significant impact currently; it'll help an upcoming change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@68667 91177308-0d34-0410-b5e6-96231b3b80d8
