2010-04-12Simplify this code.Dan Gohman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101074 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Build system fixes. llvm-mc depends onSean Callanan
libEnhancedDisassembly, so we now build the static library in all cases (although the shared library is only built when requested/possible). Also, fixed a bug where edis wasn't properly initializing the targets it uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101072 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Suppress LinearFunctionTestReplace when the computed backedge-takenDan Gohman
expression is a UDiv and it doesn't appear that the UDiv came from the user's source. ScalarEvolution has recently figured out how to compute a tripcount expression for the inner loop in SingleSource/Benchmarks/Shootout/sieve.c, using a udiv. Emitting a udiv instruction dramatically slows down the enclosing loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101068 91177308-0d34-0410-b5e6-96231b3b80d8

flags work properly when EDIS_VERSION is defined git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101063 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Bug fix: included System/Types.h instead ofSean Callanan
inttypes.h to allow building on Windows. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101062 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Second try at integrating the edis tester. ThisSean Callanan
time I use the LIBS variable, which is not subject to a %.a -> -l% transformation, to link llvm-mc against libEnhancedDisassembly. llvm-mc -edis works the same as llvm-mc -disassemble, but outputs tokens and operands. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101058 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Fixed a crasher in arm disassembler within ARMInstPrinter.cpp after callingJohnny Chen
ARM_AM::getSoImmVal(V) with a legitimate so_imm value: #245 rotate right by 2. Introduce ARM_AM::getSOImmValOneOrNoRotate(unsigned Arg) which is called from ARMInstPrinter.cpp's printSOImm() function, replacing ARM_AM::getSOImmVal(V).

2010-04-12Remove unneeded debug in PostDominator runOnFunction()Tobias Grosser
The information is already available with "opt -analyze". The DominatorTree does also not have this in its runOnFunction. So they behave now more consistent. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101038 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-12Move the EliminateIVUsers call back out to its original location. Now thatDan Gohman
a ScalarEvolution bug with overflow handling is fixed, the normal analysis code will automatically decline to operate on the icmp instructions which are responsible for the loop exit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101032 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Generalize ScalarEvolution's PHI analysis to handle loops that don'tDan Gohman
have preheaders or dedicated exit blocks, as clients may not otherwise need to run LoopSimplify. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101030 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Rewrite the overflow checking in the get{Signed,Unsigned}Range code forDan Gohman
AddRecs so that it checks for overflow in the computation that it is performing, rather than just checking hasNo{Signed,Unsigned}Wrap, since those flags are for a different computation. This fixes a bug that impacts an upcoming change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101028 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-12Use RecursivelyDeleteTriviallyDeadInstructions in EliminateIVComparisons,Dan Gohman
instead of deleting just the user. This makes it more consistent with other code in IndVarSimplify, and theoretically can eliminate more users earlier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101027 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-12Re-apply r101000, with a fix: Don't eliminate an icmp which is part ofDan Gohman
the loop exit test. This usually doesn't come up for a variety of reasons, but it isn't impossible, so make IndVarSimplify handle it conservatively. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101008 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-11Teach IndVarSimplify how to eliminate comparisons involving inductionDan Gohman
variables. For example, with code like this: for (i=0;i<n;++i) if (i<n) x[i] = 0; IndVarSimplify will now recognize that i is always less than n inside the loop, and eliminate the if. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@101000 91177308-0d34-0410-b5e6-96231b3b80d8

2010-04-10configure: Fix default value for optimize_option, I messed up the test conditionDaniel Dunbar
in r86005 and unintentionally changed the default from -O3 to -O2. - It's odd the things automated perf testing turns up! :) - Also, the configure diff is messed up slightly. It looks like someone either didn't regenerate configure correctly (or I didn't), or autoconf has some funnyness in it. Eric, any ideas? This has been at -O2 for so long, that I am slightly nervous that this change will uncover miscompiles of LLVM on other systems. If that is the case, I think we should just set the default universally at -O3, and let developers/vendors use -O3 if they want it and have tested it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@100941 91177308-0d34-0410-b5e6-96231b3b80d8
