* TEMPORARY SYNTAX CHANGE!Bill Wendling2013-02-091-4/+7
| | | | | | | | | | | | | | | | | The original syntax for the attribute groups was ambiguous. For example: declare void @foo() #1 #0 = attributes { noinline } The '#0' would be parsed as an attribute reference for '@foo' and not as a top-level entity. In order to continue forward while waiting for a decision on what the correct syntax is, I'm changing it to this instead: declare void @foo() #1 attributes #0 = { noinline } Repeat: This is TEMPORARY until we decide what the correct syntax should be. llvm-svn: 174813

* Fix a nasty off-by one error that only manifests with 64-bit word size (which isChris Lattner2013-02-091-1/+1

* Fix the underlying problem that was causing read(0) to be called: sometimes theChris Lattner2013-02-092-5/+16
| | | | | | | | | | | | | | | bitcode writer would generate abbrev records saying that the abbrev should be filled with fixed zero-bit bitfields (this happens in the .bc writer when the number of types used in a module is exactly one, since log2(1) == 0). In this case, just handle it as a literal zero. We can't "just fix" the writer without breaking compatibility with existing bc files, so have the abbrev reader do the substitution. Strengthen the assert in read to reject reads of zero bits so we catch such crimes in the future, and remove the special case designed to handle this. llvm-svn: 174801
* recommit r173072 (preparing bitstream reader to read a machine word at a time,Chris Lattner2013-02-091-21/+51
| | | | | | | | | | | instead of always 32-bits at a time) with two changes: 1. Make Read(0) always return zero without affecting the state of our cursor. 2. Hack word_t to always be 32 bits, as staging. These two caveats will change shortly. llvm-svn: 174800

* Remove the old liveness algorithm.Jakob Stoklund Olesen2013-02-092-333/+5

* Enable *BasicBlockPass::createPrinterPass()Sergei Larin2013-02-086-2/+46

* 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. llvm-svn: 174774
* 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. llvm-svn: 174773
* 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. llvm-svn: 174770

* 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. llvm-svn: 174748

| | | | | | | | | | 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. llvm-svn: 174747
* 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. llvm-svn: 174746
* 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! llvm-svn: 174743

* 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> llvm-svn: 174741
* Update PowerPC links in CompilerWriterInfo.rstHal Finkel2013-02-081-7/+7
| | | | | | | | | | This updates the current references to links that work for me. In the future, we should update the list of references itself to provide information on newer architecture variants. Thanks to Sean Silva for pointing out that the current links were broken! llvm-svn: 174739
* Refine fix to bug 15041.Bill Schmidt2013-02-082-18/+33
| | | | | | | | | Thanks to help from Nadav and Hal, I have a more reasonable (and even correct!) approach. This specifically penalizes the insertelement and extractelement operations for the performance hit that will occur on PowerPC processors. llvm-svn: 174725
* [SimplifyLibCalls] Library call simplification doen't work if the call site Chad Rosier2013-02-082-1/+55

* The patch to fix some issues in r174543 fixed the lines failing the test, ↵David Tweed2013-02-081-3/+3
| | | | | | | | | but missed a couple of lines which weren't being explicitly looked at and were printing incorrect results. These values clearly must lie within 32 bits, so the casts are definitely safe. llvm-svn: 174717
* 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 llvm-svn: 174713

* Parse the attribute group reference on a function.Bill Wendling2013-02-082-8/+94
| | | | | | | | | | | Attribute references are of this form: define void @foo() #0 #1 #2 { ... } Parse them for function attributes. If there's more than one reference, then they are merged together. llvm-svn: 174697
