* [InstCombine] Do not exercise nested max/min pattern on absAnna Thomas2017-02-212-1/+25
| | | | | | | | | | | | | | | | | | | Summary: This is a fix for assertion failure in `getInverseMinMaxSelectPattern` when ABS is passed in as a select pattern. We should not be invoking the simplification rule for ABS(MIN(~ x,y))) or ABS(MAX(~x,y)) combinations. Added a test case which would cause an assertion failure without the patch.

* [clang-tidy] Reword the "code outside header guard" warning.Benjamin Kramer2017-02-212-65/+95
| | | | | | | | | | | | The check doesn't really know if the code it is warning about came before or after the header guard, so phrase it more neutral instead of complaining about code before the header guard. The location for the warning is still not optimal, but I don't think fixing that is worth the effort, the preprocessor doesn't give us a better location.

* [DeLICM] Map values hoisted by LICM back to the array.Michael Kruse2017-02-212-5/+1379
| | | | | | | | | | | | | | | | | | | | Implement the -polly-delicm pass. The pass intends to undo the effects of LoopInvariantCodeMotion (LICM) which adds additional scalar dependencies into SCoPs. DeLICM will try to map those scalars back to the array elements they were promoted from, as long as the array element is unused. The is the main patch from the DeLICM/DePRE patch series. It does not yet undo GVN PRE for which additional information about known values is needed and does not handle PHI write accesses that have have no target. As such its usefulness is limited. Patches for these issues including regression tests for error situatons will follow. Reviewers: grosser Differential Revision: https://reviews.llvm.org/D24716 llvm-svn: 295713
* Log: Fix race in accessing the stream variablePavel Labath2017-02-213-1/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The code was attempting to copy the shared pointer member in order to guarantee atomicity, but this is not enough. Instead, protect the pointer with a proper read-write mutex. This bug was present here for a long time, but my recent refactors must have altered the timings slightly, such that now this fails fairly often when running the tests: the test runner runs the "log disable" command just as the thread monitoring the lldb-server child is about to report that the server has exited. I add a test case for this. It's not possible to reproduce the race deterministically in normal circumstances, but I have verified that before the fix, the test failed when run under tsan, and was running fine afterwards.

* [ELF] - Make ASSERT() return Dot instead of evaluated value.George Rimar2017-02-213-7/+5
| | | | | | | | | | | | | | | | | | | | Previously ASSERT we implemented returned expression value. Ex: . = ASSERT(0x100); would set Dot value to 0x100 Form of assert when it is assigned to Dot was implemented for compatibility with very old GNU ld which required it. Some scripts in the wild, including linux kernel scripts use such ASSERTs at the end for doing different checks. Currently we fail with "unable to move location counter backward" for such scripts. Patch changes ASSERT to return location counter value to fix that. Differential revision: https://reviews.llvm.org/D30171 llvm-svn: 295703

With BMI2 we will use RORX as we currently do. Reviewers: zvi Reviewed By: zvi Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D30181 llvm-svn: 295697
* PR32010: Fix template argument depth mixup when forming implicit constructorRichard Smith2017-02-217-41/+113
| | | | | | | | | | | | | template deduction guides for class template argument deduction. Ensure that we have a local instantiation scope for tracking the instantiated parameters. Additionally, unusually, we're substituting at depth 1 and leaving depth 0 alone; make sure that we don't reduce template parameter depth by 2 for inner parameters in the process. (This is probably also broken for alias templates in the case where they're expanded within a dependent context, but this patch doesn't fix that.) llvm-svn: 295696

For example, for the test code attached, the branch instruction of 'entry' block has a DILocation of ``` !12 = !DILocation(line: 6, column: 3, scope: !11) ``` , but this information is gone when then block is lowered because BranchFolder misses it.

When compiling, clients of the installation need to add -I${PREFIX}/include/polly/ to there include path right now, because there currently is no way to export this path automatically.
