* Remove the -P option from dotest.pyZachary Turner2015-12-095-175/+0
| | | | | | | | This was an option to display a graphical progress bar. Nobody is using this, and it doesn't work correctly anyway with the new result formatter. llvm-svn: 255153
* Delete the -n command line option from dotest.py.Zachary Turner2015-12-093-19/+7
| | | | | | | This removes the option to not print some one time version and diagnostic information when running the test suite. llvm-svn: 255152
* Remove the -i command line option from dotest.py.Zachary Turner2015-12-093-11/+0
| | | | | | | This is part of a larger effort to remove unused command line options from dotest.py. llvm-svn: 255151
* Delete the -F command line option from dotest.py.Zachary Turner2015-12-093-9/+0
| | | | | | | | This removes the failfast command line option as part of an effort to simplify dotest and remove unused command line options. You can still Ctrl+C any time you want to exit early. llvm-svn: 255150
* Don't assign a temporary string to a StringRef.Rafael Espindola2015-12-091-1/+1

* Use WeakVH to keep track of calls with operand bundles in CloneCodeInfoSanjoy Das2015-12-093-3/+37
| | | | | | | | `CloneAndPruneIntoFromInst` can DCE instructions after cloning them into the new function, and so an AssertingVH is too strong. This change switches CloneCodeInfo to use a std::vector<WeakVH>. llvm-svn: 255148

* Remove -e option from dotest.py.Zachary Turner2015-12-097-27/+8
| | | | | | | This is part of an effort to clean up dotest command line options that are no longer used. llvm-svn: 255142
* Remove -libcxx option from dotest.pyZachary Turner2015-12-092-4/+0
| | | | | | | Nobody was using this, and plus it can be achieved just as well by using -E to set an environment variable. llvm-svn: 255141

* Fix new summary to include exceptional exit count in determining exit valueTodd Fiala2015-12-092-14/+35
| | | | | | | | | | | | The main dotest.py should exit with a system return code of 1 on any issue. This change fixes a place where I omitted counting the exceptional exit value to determine if we should return 1 when using the new summary results. This change also puts a banner around the Issue Details section that comes before the Test Result Summary. llvm-svn: 255138
* [InstCombine] fold bitcasts around an extractelement (2nd try)Sanjay Patel2015-12-092-8/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a redo of r255124 (reverted at r255126) with an added check for a scalar destination type and an added test for the failure seen in Clang's test/CodeGen/vector.c. The extra test shows a different missing optimization. Original commit message: Example: bitcast (extractelement (bitcast <2 x float> %X to <2 x i32>), 1) to float ---> extractelement <2 x float> %X, i32 1 This is part of fixing PR25543: https://llvm.org/bugs/show_bug.cgi?id=25543 The next step will be to generalize this fold: trunc ( lshr ( bitcast X) ) -> extractelement (X) Ie, I'm hoping to replace the existing transform of: bitcast ( trunc ( lshr ( bitcast X))) added by: http://reviews.llvm.org/rL112232 with 2 less specific transforms to catch the case in the bug report.

* [TSan] Try harder to avoid compiler-generated memset calls.Alexey Samsonov2015-12-095-6/+8
| | | | | | | | | | check_memcpy test added in r254959 fails on some configurations due to memset() calls inserted by Clang. Try harder to avoid them: * Explicitly use internal_memset() instead of empty braced-initializer. * Replace "new T()" with "new T", as the former generates zero-initialization for structs in C++11. llvm-svn: 255136

* [PGO] Resubmit "MST based PGO instrumentation infrastructure" (r254021)Rong Xu2015-12-0929-1/+1570
| | | | | | | | | | | | | | | This new patch fixes a few bugs that exposed in last submit. It also improves the test cases. --Original Commit Message-- This patch implements a minimum spanning tree (MST) based instrumentation for PGO. The use of MST guarantees minimum number of CFG edges getting instrumented. An addition optimization is to instrument the less executed edges to further reduce the instrumentation overhead. The patch contains both the instrumentation and the use of the profile to set the branch weights. Differential Revision: http://reviews.llvm.org/D12781 llvm-svn: 255132

The effect of this change will be reverted after verifying the testbot behavior.

* [WebAssembly] Reintroduce ARGUMENT moving logicDan Gohman2015-12-0910-7/+123
| | | | | | | | | | | | | | | | | | | Reinteroduce the code for moving ARGUMENTS back to the top of the basic block. While the ARGUMENTS physical register prevents sinking and scheduling from moving them, it does not appear to be sufficient to prevent SelectionDAG from moving them down in the initial schedule. This patch introduces a patch that moves them back to the top immediately after SelectionDAG runs. This is still hopefully a temporary solution. http://reviews.llvm.org/D14750 is one alternative, though the review has not been favorable, and proposed alternatives are longer-term and have other downsides. This fixes the main outstanding -verify-machineinstrs failures, so it adds -verify-machineinstrs to several tests. Differential Revision: http://reviews.llvm.org/D15377 llvm-svn: 255125

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ScalarEvolution.h, in order to avoid cyclic dependencies between the Transform and Analysis modules: [LV][LAA] Add a layer over SCEV to apply run-time checked knowledge on SCEV expressions Summary: This change creates a layer over ScalarEvolution for LAA and LV, and centralizes the usage of SCEV predicates. The SCEVPredicatedLayer takes the statically deduced knowledge by ScalarEvolution and applies the knowledge from the SCEV predicates. The end goal is that both LAA and LV should use this interface everywhere. This also solves a problem involving the result of SCEV expression rewritting when the predicate changes. Suppose we have the expression (sext {a,+,b}) and two predicates P1: {a,+,b} has nsw P2: b = 1. Applying P1 and then P2 gives us {a,+,1}, while applying P2 and the P1 gives us sext({a,+,1}) (the AddRec expression was changed by P2 so P1 no longer applies). The SCEVPredicatedLayer maintains the order of transformations by feeding back the results of previous transformations into new transformations, and therefore avoiding this issue. The SCEVPredicatedLayer maintains a cache to remember the results of previous SCEV rewritting results. This also has the benefit of reducing the overall number of expression rewrites.

* Fix cycle in selection DAG introduced by extractelement legalizationRobert Lougher2015-12-092-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | During selection DAG legalization, extractelement is replaced with a load instruction. To do this, a temporary store to the stack is used unless an existing store is found that can be re-used. If re-using a store, the chain going out of the store must be replaced by the one going out of the new load (this ensures that any stores that must take place after the store happens after the load, else the value might be overwritten before it is loaded). The problem is, if the extractelement index is dependent on the store replacing the chain will introduce a cycle in the selection DAG (the load uses the index, and by replacing the chain we will make the index dependent on the load). To fix this, if the index is dependent on the store, the store is skipped. This is conservative as we may end up creating an unnecessary extra store to the stack. However, the situation is not expected to occur very often. Differential Revision: http://reviews.llvm.org/D15330 llvm-svn: 255114
