2010-04-14Enable RTTI again. While this works fine for LLVM, it creates an ABINick Lewycky
incompatibility with some clients covered by the buildbots, such as llvm-gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101237 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-14While DAE can't modify the function signature of an externally visible function,Nick Lewycky
it can check whether the visible direct callers are passing in parameters to dead arguments and replace those with undef. This reinstates r94322 with bugs fixed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101213 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-14Fixed another assert exposed by fuzzing. Now, when an encoding error occursJohnny Chen
involing getBFCInvMask() where lsb <= msb does not hold true, the disassembler just returns false, instead of assert, to indicate disassembly error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101205 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-14Fixed an assert() exposed by fuzzing. Now, instead of assert when an invalidJohnny Chen
instruction encoding is encountered, we just return a NULL ARMBasicMCBuilder instance and the client just returns false to indicate disassembly error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101201 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13Unbreak CMake build by improving the EnhancedDisassembly makefile aDouglas Gregor

2010-04-13Fixed a nasty layering violation in the edis sourceSean Callanan
code. It used to #include the enhanced disassembly information for the targets it supported straight out of lib/Target/{X86,ARM,...} but now it uses a new interface provided by MCDisassembler, and (so far) implemented by X86 and ARM. Also removed hacky #define-controlled initialization of targets in edis. If clients only want edis to initialize a limited set of targets, they can set --enable-targets on the configure command line. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101179 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13Changed getSOImmValRotate()'s hunt retry logic to ignore the low order 6 bits,Johnny Chen
instead of 7, because we are only looking for even rotate amount. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101172 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13Expand postra machine licm's capability a little more. If an instruction's ↵Evan Cheng
register operands are all loop invariants, then it's safe to hoist it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101167 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13Teach MachineSinking to handle easy critical edges.Jakob Stoklund Olesen
Sometimes it is desirable to sink instructions along a critical edge: x = ... if (a && b) ... else use(x); The 'a && b' condition creates a critical edge to the else block, but we still want to sink the computation of x into the block. The else block is dominated by the parent block, so we are not pushing instructions into new code paths. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101165 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13Re-apply 101075 and fix it properly. Just reuse the debug info of the branch ↵Evan Cheng
instruction being optimized. There is no need to --I which can deref off start of the BB. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101162 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13Teach postra machine licm to hoist more obvious invariants, e.g. ↵Evan Cheng
instructions with no source operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101154 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13Eliminate MachineBasicBlock::const_livein_iterator and makeDan Gohman
MachineBasicBlock::livein_iterator a const_iterator, because clients shouldn't ever be using the iterator interface to mutate the livein set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101147 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13Let BumpPtrAllocator lazily allocate the first slab.Benjamin Kramer
We have some code in llvm and clang where a BumpPtrAllocator is declared in a class but never used in the common case. Stop wasting memory there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101130 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-13Replace r101053 with a fix for getSOImmValRotate() so that it will correctlyBob Wilson
recognize all the valid rotated immediates. This fixes the disassembler issue and will also help codegen for some unusual constant values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101114 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13Teach IndVarSimplify how to eliminate remainder operators where theDan Gohman
numerator is an induction variable. For example, with code like this: for (i=0;i<n;++i) x[i%n] = 0; IndVarSimplify will now recognize that i is always less than n inside the loop, and eliminate the remainder. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101113 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-13VMCore: Add Type::getIntN[Ptr]Ty, which are the obvious generic forms ofDaniel Dunbar
Type::getInt{1,8,...}[Ptr]Ty, so code can consistently use the methods on Type without occasionally needed to call IntegerType::get. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101111 91177308-0d34-0410-b5e6-96231b3b80d8
