* [IRCE] Don't misuse CHECK-LABEL; NFCSanjoy Das2016-07-225-30/+31
| | | | llvm-svn: 276373
* [IRCE] Add an option to skip profitability checksSanjoy Das2016-07-222-2/+38
| | | | | | | | If `-irce-skip-profitability-checks` is passed in, IRCE will kick in in all cases where it is legal for it to kick in. This flag is intended to help diagnose and analyse performance issues. llvm-svn: 276372

| | | | llvm-svn: 276368
* [AArch64] Cleanup sign extend in genAlternativeCodeSequenceDavid Majnemer2016-07-211-3/+3
| | | | | | | | Use the machinery in MathExtras instead of rolling it by hand. This fixes PR28624. llvm-svn: 276366
* GVN-hoist: add missing check for all GEP operands availableSebastian Pop2016-07-211-0/+3

* [InstCombine] break up foldICmpEqualityWithConstant(); NFCISanjay Patel2016-07-212-148/+161
| | | | | | | Almost all of these folds require changes to allow vector types. Splitting up the logic should make that easier to do incrementally. llvm-svn: 276360
* [llvm-cov] Use relative paths to the stylesheet (for html reports)Vedant Kumar2016-07-213-58/+95
| | | | | | | | | | This makes it easy to swap out the default stylesheet for a custom one. It also shaves ~6.62 MB out of the report directory for a full coverage build of llvm+clang. While we're at it, prune the CSS and add tests for it. llvm-svn: 276359
* GVH-hoist: only clone GEPs (PR28606)Sebastian Pop2016-07-213-16/+59
| | | | | | | | | Do not clone stored values unless they are GEPs that are special cased to avoid hoisting them without hoisting their associated ld/st. Differential revision: https://reviews.llvm.org/D22652 llvm-svn: 276358
* [lit] Use full config path in diagnostics.Daniel Dunbar2016-07-211-1/+1
| | | | | | | | | - This allows tools like emacs to automatically find the config file path when you step through errors. - Patch by Dave Abrahams. llvm-svn: 276357
* [Profile] deprecate __llvm_profile_override_default_filenameXinliang David Li2016-07-212-16/+20

* [MIRTesting] Abort when failing to parse a function.Quentin Colombet2016-07-215-37/+46
| | | | | | | | | | When we failed to parse a function in the mir parser, we should abort the whole compilation instead of continuing in a weird state. Indeed, this was creating strange machine function passes failures that were hard to understand, until we notice that the function actually did not get parsed correctly! llvm-svn: 276348
* [X86] Do not use AND8ri8 in AVX512 patternMichael Kuperstein2016-07-212-1/+19
| | | | | | | This variant is (as documented in the TD) for disassembler use only, and should not be used in patterns - it is longer, and is broken on 64-bit. llvm-svn: 276347

* [AArch64][Inline-Asm] Return the 32-bit floating point register classAkira Hatanaka2016-07-212-1/+9
| | | | | | | | | | | | | | | when constraint "w" is used on a 32-bit operand. This enables compiling the following code, which used to error out in the backend: void foo1(int a) { asm volatile ("sqxtn h0, %s0\n" : : "w"(a):); } Fixes PR28633. llvm-svn: 276344
* [cmake] Move the including of utils/unittests under LLVM_INCLUDE_UTILS ↵Michael Gottesman2016-07-211-4/+1
| | | | | | | | | | | | | | | | | | | | instead of LLVM_INCLUDE_TESTS. This does not change anything by default since LLVM_INCLUDE_UTILS is already set to TRUE by default. In addition, since LLVM_INCLUDE_TESTS => LLVM_INCLUDE_UTILS, the only way that this can cause changes is in the case where LLVM_INCLUDE_UTILS is set to TRUE, but LLVM_INCLUDE_TESTS is FALSE. In that case, building gtest is not a huge cost. The reason to do this is that without this change, one can not turn off LLVM_INCLUDE_TESTS in downstream projects that also use gtest for unittests. It also just in general makes more sense since LLVM_INCLUDE_UTILS gates FileCheck and other utilities that are along the lines of gtest. Additionally from talking with chandlerc, this was not done for any specific reason, so there is no reason not to do it and lots of benefit to doing it. llvm-svn: 276342
* [InstSimplify] recognize trunc + icmp sgt/slt variants of select ↵Sanjay Patel2016-07-212-48/+42
| | | | | | | | | | | | | | | | | | simplifications (PR28466) rL245171 exposed a hole in InstSimplify that manifested in a strange way in PR28466: https://llvm.org/bugs/show_bug.cgi?id=28466 It's possible to use trunc + icmp sgt/slt in place of an and + icmp eq/ne, so we need to recognize that pattern to eliminate selects that are choosing between some value and some bitmasked version of that value. Note that there is significant room for improvement (refactoring) and enhancement (more patterns, possibly in InstCombine rather than here).

* [LV] Move vector int induction update to end of latchMatthew Simpson2016-07-214-17/+27
| | | | | | | | | | | This patch moves the update instruction for vectorized integer induction phi nodes to the end of the latch block. This ensures consistent placement of all induction updates across all the kinds of int inductions we create (scalar, splat vector, or vector phi).

* Fix the clang-cl self-host with VS 2013 headersReid Kleckner2016-07-211-2/+1
| | | | | | | | std::numeric_limits<int64_t>::max() is not constexpr in VC 2013 headers, and Clang complains that it isn't. MSVC 2013 itself is emitting a dynamic initializer for this thing. Instead, use an enum. llvm-svn: 276334

| | | | | | | | Given that other proposals are making their way through, it's better if we specify what GitHub proposal this is, in case there are others that also involve GitHub, but not sub-modules. llvm-svn: 276325

* Invariant start/end intrinsics overloaded for address spaceAnna Thomas2016-07-219-23/+78
| | | | | | | | | | | | | | | | | | | | | Summary: The llvm.invariant.start and llvm.invariant.end intrinsics currently support specifying invariant memory objects only in the default address space. With this change, these intrinsics are overloaded for any adddress space for memory objects and we can use these llvm invariant intrinsics in non-default address spaces. Example: llvm.invariant.start.p1i8(i64 4, i8 addrspace(1)* %ptr) This overloaded intrinsic is needed for representing final or invariant memory in managed languages.

* [llvm-config][GlobalISel] Canonicalize LLVM_HAS_GLOBAL_ISEL on ON/OFF.Quentin Colombet2016-07-211-1/+5
| | | | | | | | | | | Previously LLVM_HAS_GLOBAL_ISEL would directly get the value of LLVM_BUILD_GLOBAL_ISEL. This could be any integer value and not just ON and OFF. The problem is that lit.cfg was checking for ON to define that global-isel was supported, thus if we were setting LLVM_BUILD_GLOBAL_ISEL with an integer value, say 1, this test would fail whereas we do build global-isel and want to test it. llvm-svn: 276307
* [CMake][GlobalISel] Turn LLVM_BUILD_GLOBAL_ISEL into an option. NFC.Quentin Colombet2016-07-211-1/+1
| | | | | | | | Previously LLVM_BUILD_GLOBAL_ISEL was a boolean variable and although, this is strictly identical to an option, it did not convey the information that the user may set it. Options are here for that. llvm-svn: 276306

* Weaken ThreadSafeRefCountedBase atomics.Benjamin Kramer2016-07-211-2/+2

* [X86][SSE] Allow folding of store/zext with PEXTRW of 0'th elementSimon Pilgrim2016-07-2118-131/+85
| | | | | | | | | | | | | | Under normal circumstances we prefer the higher performance MOVD to extract the 0'th element of a v8i16 vector instead of PEXTRW. But as detailed on PR27265, this prevents the SSE41 implementation of PEXTRW from folding the store of the 0'th element. Additionally it prevents us from making use of the fact that the (SSE2) reg-reg version of PEXTRW implicitly zero-extends the i16 element to the i32/i64 destination register. This patch only preferentially lowers to MOVD if we will not be zero-extending the extracted i16, nor prevent a store from being folded (on SSSE41). Fix for PR27265.

* [X86][AVX] Added support for lowering to VBROADCASTF128/VBROADCASTI128Simon Pilgrim2016-07-2111-207/+167
| | | | | | | | | | | | As reported on PR26235, we don't currently make use of the VBROADCASTF128/VBROADCASTI128 instructions (or the AVX512 equivalents) to load+splat a 128-bit vector to both lanes of a 256-bit vector. This patch enables lowering from subvector insertion/concatenation patterns and auto-upgrades the llvm.x86.avx.vbroadcastf128.pd.256 / llvm.x86.avx.vbroadcastf128.ps.256 intrinsics to match. We could possibly investigate using VBROADCASTF128/VBROADCASTI128 to load repeated constants as well (similar to how we already do for scalar broadcasts).
