* Revert "[MachineOutliner] Never add the outliner in -O0"Jessica Paquette2018-06-282-18/+5
| | | | | | | | | | | This reverts commit 9c7c10e4073a0bc6a759ce5cd33afbac74930091. It relies on r335872 since that introduces the machine outliner flags test. I meant to commit D48683 in that commit, but got mixed up and committed D48682 instead. So, I'm reverting this and r335872, since D48682 hasn't made it through review yet. llvm-svn: 335882

* [MachineOutliner] Never add the outliner in -O0Jessica Paquette2018-06-282-5/+18
| | | | | | | | | | | We shouldn't add the outliner when compiling at -O0 even if -enable-machine-outliner is passed in. This makes sure that we don't add it in this case. This also updates machine-outliner-flags to reflect the change and improves the comment describing what that test does. llvm-svn: 335879

Enable the feature on Mach-O to save code size; Comments suggest it is not possible to enable it for the other users of TrapUnreachable. rdar://41530228 DifferentialRevision: https://reviews.llvm.org/D48674 llvm-svn: 335877

* [MachineOutliner] Add always and never options to -enable-machine-outlinerJessica Paquette2018-06-282-4/+42
| | | | | | | | | | | | | To enable the MachineOutliner by default on AArch64, we need to be able to disable the MachineOutliner and also provide an option to "always" enable the outliner. This adds that capability. It allows the user to still use the old -enable-machine-outliner option, which defaults to "always". This is building up to allowing the user to specify "always" versus the target-default outlining behaviour. llvm-svn: 335872

* [AMDGPU] Early expansion of 32 bit udiv/uremStanislav Mekhanoshin2018-06-284-132/+2747
| | | | | | | | | | | | This allows hoisting of a common code, for instance if denominator is loop invariant. Current change is expansion only, adding licm to the target pass list going to be a separate patch. Given this patch changes to codegen are minor as the expansion is similar to that on DAG. DAG expansion still must remain for R600. Differential Revision: https://reviews.llvm.org/D48586 llvm-svn: 335868
* [llvm-mca] Use a WriteRef to describe register writes in class RegisterFile.Andrea Di Biagio2018-06-286-50/+103
| | | | | | | | | | | This patch introduces a new class named WriteRef. A WriteRef is used by the RegisterFile to keep track of register definitions. Internally it wraps a WriteState, as well as the source index of the defining instruction. This patch allows the tool to propagate additional information to support future analysis on data dependencies. llvm-svn: 335867

* lld-link: align sections to 16 bytes if referenced from the gfids tableBob Haarman2018-06-283-0/+101
| | | | | | | | | | | | | | | | | | | Summary: Control flow guard works best when targets it checks are 16-byte aligned. Microsoft's link.exe helps ensure this by aligning code from sections that are referenced from the gfids table to 16 bytes when linking with -guard:cf, even if the original section specifies a smaller alignment. This change implements that behavior in lld-link. See https://crbug.com/857012 for more details.

* Skip core file tests on build configurations lacking necessary componentsPavel Labath2018-06-283-0/+33
| | | | | | | | | | | | | | | | | | | Summary: To successfully open a core file, we need to have LLVM built with support for the relevant target. Right now, if one does not have the appropriate targets configured, the tests will fail. This patch uses the GetBuildConfiguration SB API to inform the test (and anyone else who cares) about the list of supported LLVM targets. The test then uses this information to approriately skip the tests.

* [ODRHash] Do not rely on Type* when computing the hash.Vassil Vassilev2018-06-288-10/+46
| | | | | | | | | | | | | | | | | ODRHash aims to provide Cross-TU stable hashing. Making clang::Type pointer part of the hash connects (remotely) the ODRHash with the TU-specific ::Profile hasher. r332281 exposed the issue by changing the way the ASTContext different elaborated types if there is an owning tag. In that case, ODRHash stores two different types in its TypeMap which yields false ODR violation in modules. The current state of implementation shouldn't need the TypeMap concept anymore.

* [ARM] Parallel DSP PassSjoerd Meijer2018-06-2818-1/+1301
| | | | | | | | | | | | | | | | | Armv6 introduced instructions to perform 32-bit SIMD operations. The purpose of this pass is to do some straightforward IR pattern matching to create ACLE DSP intrinsics, which map on these 32-bit SIMD operations. Currently, only the SMLAD instruction gets recognised. This instruction performs two multiplications with 16-bit operands, and stores the result in an accumulator. We will follow this up with patches to recognise SMLAD in more cases, and also to generate other DSP instructions (like e.g. SADD16).
