* [clang] -foptimization-record-file= should imply -fsave-optimization-recordJonas Devlieghere2017-12-192-0/+4
| | | | | | | | | | | | | | | | | The Clang option -foptimization-record-file= controls which file an optimization record is output to. Optimization records are output if you use the Clang option -fsave-optimization-record. If you specify the first option without the second, you get a warning that the command line argument was unused. Passing -foptimization-record-file= should imply -fsave-optimization-record.

* [ThinLTO][C-API] Correct api commentsBen Dunbobbin2017-12-192-11/+12
| | | | | | | | | | | | Negative values never disabled the pruning - they simply set high values for the pruning interval. The behaviour now is that negative values set the maximum pruning interval (which appears to have been the intention from the start) see https://reviews.llvm.org/D41231. I have adjusted the comments to reflect this, removed any inaccurate statements, and corrected any typos I spotted in the English.

* [Support][CachePruning] Disable cache pruning regression fixBen Dunbobbin2017-12-194-6/+32
| | | | | | | | | | borked by: rL284966 (see: https://reviews.llvm.org/D25730). Previously, Interval was unsigned (see: CachePruning.h), replacing the type with std::chrono::seconds (which is signed) causes a regression in behaviour because the c-api intends negative values to translate to large positive intervals to *effectively* disable the pruning (see comments on: setCachePruningInterval()).

* [X86][SSE] Add cpu feature for aggressive combining to variable shufflesSimon Pilgrim2017-12-1910-498/+1362
| | | | | | | | | | | | As mentioned in D38318 and D40865, modern Intel processors prefer to combine multiple shuffles to a variable shuffle mask (PSHUFB/VPERMPS etc.) instead of having multiple stage 'fixed' shuffles which put more pressure on Port 5 (at the expense of extra shuffle mask loads). This patch provides a FeatureFastVariableShuffle target flag for Haswell+ CPUs that prefers combining 2 or more fixed shuffles to a single variable shuffle (default is 3 shuffles). The long term aim is to drive more of this from schedule data (probably via the MC) but we're not close to being ready for that yet.

* [Support] Add WritableMemoryBuffer classPavel Labath2017-12-193-61/+190
| | | | | | | | | | | | | | | | | | | | | | | | Summary: The motivation here is LLDB, where we need to fixup relocations in mmapped files before their contents can be read correctly. The MemoryBuffer class does exactly what we need, *except* that it maps the file in read-only mode. WritableMemoryBuffer reuses the existing machinery for opening and mmapping a file. The only difference is in the argument to the mapped_file_region constructor -- we create a private copy-on-write mapping, so that we can make changes to the mapped data, but the changes aren't carried over to the underlying file. This patch is based on an initial version by Zachary Turner.

Given that for many current platforms the load address already exceeds unsigned (e.g. arm64 w/ 0x100000000), dwarfdump needs an unsigned long long parameter.

* [X86] Use ZERO_EXTEND instead of ANY_EXTEND when extending the shift amount ↵Craig Topper2017-12-191-1/+1
| | | | | | | | | | for a non-uniform shift. My reading of the SDM says that all bits of the shift amount are used. If the value of the element is larger than the number of bits the result the shift result is zero. So I think we need to zero_extend here to avoid garbage in the upper bits. In reality we lower any_extend as zero_extend so in most cases it would be hard to hit this. llvm-svn: 321055
