* Enable *BasicBlockPass::createPrinterPass()Sergei Larin2013-02-086-2/+46
| | | | | | | | Enables raw_ostream I/O for BasicBlockPass. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174776 91177308-0d34-0410-b5e6-96231b3b80d8
* Turn on -new-live-intervals by default.Jakob Stoklund Olesen2013-02-081-3/+3
| | | | | | | | This uses a liveness algorithm that does not depend on data from the LiveVariables analysis, it is the first step towards removing LiveVariables completely. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174774 91177308-0d34-0410-b5e6-96231b3b80d8
* CMake: Use check_symbol_exists instead of check_cxx_symbol_exists.Jordan Rose2013-02-081-7/+6
| | | | | | | | | | | check_cxx_symbol_exists requires CMake 2.8.6, so even though I recommended it to Owen it's probably better to stay away for now. This check is not technically correct because we're checking <math.h> but then using <cmath> in the actual code, but if we run into problems we can do the same sort of dance as isinf() and isnan() where we check /both/ headers and then write a wrapper header around them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174773 91177308-0d34-0410-b5e6-96231b3b80d8
* configure: when performing a compiler feature test for a -Wno-foo flag, attemptRichard Smith2013-02-082-14/+10
| | | | | | | | | | to use -Wfoo instead of -Wno-foo. This works around a bug in some versions of gcc, where it will silently accept an unknown -Wno-foo option, but will generate an error for a compile which uses -Wno-foo if that compile also triggers any warnings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174770 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert "Add LLVMContext::emitWarning methods and use them. ↵Bob Wilson2013-02-088-75/+31
| | | | | | | | | | | | | <rdar://problem/12867368>" This reverts r171041. This was a nice idea that didn't work out well. Clang warnings need to be associated with warning groups so that they can be selectively disabled, promoted to errors, etc. This simplistic patch didn't allow for that. Enhancing it to provide some way for the backend to specify a front-end warning type seems like overkill for the few uses of this, at least for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174748 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | same so we put in the comment field an indicator when we think we are emitting the 16 bit version. For the direct object emitter, the difference is important as well as for other passes which need an accurate count of program size. There will be other similar putbacks to this for various instructions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174747 91177308-0d34-0410-b5e6-96231b3b80d8
* DAGCombiner: Constant folding around pre-increment loads/storesHal Finkel2013-02-082-0/+136
| | | | | | | | | | | Previously, even when a pre-increment load or store was generated, we often needed to keep a copy of the original base register for use with other offsets. If all of these offsets are constants (including the offset which was combined into the addressing mode), then this is clearly unnecessary. This change adjusts these other offsets to use the new incremented address. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174746 91177308-0d34-0410-b5e6-96231b3b80d8
* BBVectorize: Use TTI->getAddressComputationCostHal Finkel2013-02-081-0/+5
| | | | | | | | | | | | | This is a follow-up to the cost-model change in r174713 which splits the cost of a memory operation between the address computation and the actual memory access. In r174713, this cost is always added to the memory operation cost, and so BBVectorize will do the same. Currently, this new cost function is used only by ARM, and I don't have any ARM test cases for BBVectorize. Assistance in generating some good ARM test cases for BBVectorize would be greatly appreciated! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174743 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert 172027 and 174336. Remove diagnostics about over-aligned stack objects.Bob Wilson2013-02-086-70/+24
| | | | | | | | | | | | Aside from the question of whether we report a warning or an error when we can't satisfy a requested stack object alignment, the current implementation of this is not good. We're not providing any source location in the diagnostics and the current warning is not connected to any warning group so you can't control it. We could improve the source location somewhat, but we can do a much better job if this check is implemented in the front-end, so let's do that instead. <rdar://problem/13127907> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174741 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM cost model: Address computation in vector mem ops not freeArnold Schwaighofer2013-02-089-13/+134
| | | | | | | | | | | | | | | Adds a function to target transform info to query for the cost of address computation. The cost model analysis pass now also queries this interface. The code in LoopVectorize adds the cost of address computation as part of the memory instruction cost calculation. Only there, we know whether the instruction will be scalarized or not. Increase the penality for inserting in to D registers on swift. This becomes necessary because we now always assume that address computation has a cost and three is a closer value to the architecture. radar://13097204 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174713 91177308-0d34-0410-b5e6-96231b3b80d8

* Constrain PowerPC autovectorization to fix bug 15041.Bill Schmidt2013-02-071-0/+19
| | | | | | | | | | | | | | Certain vector operations don't vectorize well with the current PowerPC implementation. Element insert/extract performs poorly without VSX support because Altivec requires going through memory. SREM, UREM, and VSELECT all produce bad scalar code.
