2007-05-14Give names to the final result values of the part_set computations. ThisReid Spencer
just aids in readability and debugability of the output. No functional change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37037 91177308-0d34-0410-b5e6-96231b3b80d8

2007-05-14Add passes -view-cfg and -view-cfg-only that are like -print-cfg andDan Gohman
-print-cfg-only except they use the ViewCFG function, which displays the CFG rendered with graphviz with gv. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37033 91177308-0d34-0410-b5e6-96231b3b80d8

2007-05-13Add some things needed by the llvm-gcc version supporting bit accurate integerReid Spencer
types: 1. Functions to compute div/rem at the same time. 2. Further assurance that an APInt with 0 bitwidth cannot be constructed. 3. Left and right rotate operations. 4. An exactLogBase2 function which requires an exact power of two or it returns -1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37025 91177308-0d34-0410-b5e6-96231b3b80d8

2007-05-13Emit function debug frames in one atom. This will prevent us from generating ↵Anton Korobeynikov

2007-05-13Emit multiple common EH frames for multiple (including blank) personalityAnton Korobeynikov
functions. This partly fixes PR1414: now we're restricted only to one personality function per eh frame, not per module. Further work on "multiple personalities" topic needs representative example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37018 91177308-0d34-0410-b5e6-96231b3b80d8
2007-05-12More DWARF-related things cleanup:Anton Korobeynikov
1. Fix PR1380 2. Apply Duncan's patch from PR1410 3. Insert workaround for "one personality function per module" as noted in PR1414 4. Emit correct debug frames for x86/linux. This partly fixes DebugInfo/2006-11-06-StackTrace.cpp: stack trace is shown correctly, but arguments for function on top of stack are displayed incorrectly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37015 91177308-0d34-0410-b5e6-96231b3b80d8
2007-05-12Fix shl to produce the correct result when the bitwidth is > 64 and theReid Spencer
shift amount is 0. Previously this code would do a lshr by the bit width which can lead to incorrect results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@37010 91177308-0d34-0410-b5e6-96231b3b80d8

2007-05-11This patch extends the LoopUnroll pass to be able to unroll loopsDan Gohman
with unknown trip counts. This is left off by default, and a command-line option enables it. It also begins to separate loop unrolling into a utility routine; eventually it might be made usable from other passes. It currently works by inserting conditional branches between each unrolled iteration, unless it proves that the trip count is a multiple of a constant integer > 1, which it currently only does in the rare case that the trip count expression is a Mul operator with a ConstantInt operand. Eventually this information might be provided by other sources, for example by a pass that peels/splits the loop for this purpose. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36990 91177308-0d34-0410-b5e6-96231b3b80d8
