2011-02-21Revert r124611 - "Keep track of incoming argument's location while emitting ↵Devang Patel
LiveIns." In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126155 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-21The signed version of our "magic number" computation for the integer ↵Cameron Zwarich
approximation of a constant had a minor typo introduced when copying it from the book, which caused it to favor negative approximations over positive approximations in many cases. Positive approximations require fewer operations beyond the multiplication. In the case of division by 3, we still generate code that is a single instruction larger than GCC's code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126097 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-20Make RecursivelyDeleteDeadPHINode delete a phi node that has no users and add aNick Lewycky
test for that. With this change, test/CodeGen/X86/codegen-dce.ll no longer finds any instructions to DCE, so delete the test. Also renamed J and JP to I and IP in RecursivelyDeleteDeadPHINode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126088 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-20Fix 9267; Add vector zext support.Nadav Rotem
The DAGCombiner folds the zext into complex load instructions. This patch prevents this optimization on vectors since none of the supported targets knows how to perform load+vector_zext in one instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126080 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-17Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 generally.NAKAMURA Takumi
No one uses *-mingw64. mingw-w64 is represented as {i686|x86_64}-w64-mingw32. In llvm side, i686 and x64 can be treated as similar way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125747 91177308-0d34-0410-b5e6-96231b3b80d8

transformation if we can't legally create a build vector of the correct type. Check that we can make the transformation first, and add a TODO to refactor this code with similar cases.

2011-02-15Ignore DBG_VALUE machine instructions while constructing instruction ranges ↵Devang Patel
based on location info. Machine instruction range consisting of only DBG_VALUE MIs only contributes consecutive labels in assembly output, which is harmless, and empty scope entry in DebugInfo, which confuses debugger tools. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125577 91177308-0d34-0410-b5e6-96231b3b80d8

2011-02-14PR9139: Specify ARM/Darwin triple for vector-DAGCombine.ll test.Bob Wilson
The i64_buildvector test in this file relies on the alignment of i64 and f64 types being the same, which is true for Darwin but not AAPCS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125525 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-14fix PR9210 by implementing some type legalization logic for Chris Lattner
vector fp conversions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125482 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-13Enhance ComputeMaskedBits to know that aligned frameindexesChris Lattner
have their low bits set to zero. This allows us to optimize out explicit stack alignment code like in stack-align.ll:test4 when it is redundant. Doing this causes the code generator to start turning FI+cst into FI|cst all over the place, which is general goodness (that is the canonical form) except that various pieces of the code generator don't handle OR aggressively. Fix this by introducing a new SelectionDAG::isBaseWithConstantOffset predicate, and using it in places that are looking for ADD(X,CST). The ARM backend in particular was missing a lot of addressing mode folding opportunities around OR. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125470 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-13when legalizing extremely wide shifts, make sure that Chris Lattner
the shift amounts are in a suitably wide type so that we don't generate out of range constant shift amounts. This fixes PR9028. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@125458 91177308-0d34-0410-b5e6-96231b3b80d8
