* LTO: Disable extra verify runs in release buildsDuncan P. N. Exon Smith2015-09-155-21/+58
| | | | | | | | | | | | | | | | | | | | | | The verifier currently runs three times in LTO: (1) after parsing, (2) at the beginning of the optimization pipeline, and (3) at the end of it. The first run is important, since we're not sure where the bitcode comes from and it's nice to validate it, but in release builds the extra runs aren't appropriate. This commit: - Allows these runs to be disabled in LTOCodeGenerator. - Adds command-line options to llvm-lto. - Adds command-line options to libLTO.dylib, and disables the verifier by default in release builds (based on NDEBUG). This shaves about 3.5% off the runtime of ld64 when linking verify-uselistorder with -flto -g. rdar://22509081 llvm-svn: 247729

* [ShrinkWrapping] Fix an infinite loop while looking for restore point.Quentin Colombet2015-09-151-0/+8
| | | | | | | | | | | This may happen when the input program itself contains an infinite loop with no exit block. In that case, we would fail to find a block post-dominating the loop such that this block is outside of the loop. This fixes PR24823. Working on reducing the test case. llvm-svn: 247710

* [SystemZ] Fix assertion failure in tryBuildVectorShuffleUlrich Weigand2015-09-152-1/+44
| | | | | | | | | | | Under certain circumstances, tryBuildVectorShuffle would attempt to create a BUILD_VECTOR node with an invalid combination of types. This happened when one of the components of the original BUILD_VECTOR was itself a TRUNCATE node. That TRUNCATE was stripped off during intermediate processing to simplify code, but when adding the node back to the result vector, we still need it to get the type right. llvm-svn: 247694
* Re-commit r247683: Replace Triple with a new TargetTuple in MCTargetDesc/* ↵Daniel Sanders2015-09-15112-499/+1289
| | | | | | | | | | | | | | | | | | | | | | | | | | | | and related. NFC. Summary: This is the first patch in the series to migrate Triple's (which are ambiguous) to TargetTuple's (which aren't). For the moment, TargetTuple simply passes all requests to the Triple object it holds. Once it has replaced Triple, it will start to implement the interface in a more suitable way. This change makes some changes to the public C++ API. In particular, InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer() now take TargetTuples instead of Triples. The other public C++ API's have been left as-is for the moment to reduce patch size. This commit also contains a trivial patch to clang to account for the C++ API change. Thanks go to Pavel Labath for fixing LLDB for me.

* [PlaceSafepoints] Make the width of a counted loop settable.Sanjoy Das2015-09-152-19/+68
| | | | | | | | | | | | | | | | | | Summary: This change lets a `PlaceSafepoints` client change how wide the trip count of a loop has to be for the loop to be considerd "counted", via `CountedLoopTripWidth`. It also removes the boolean `SkipCounted` flag and the `upperTripBound` constant -- we can get the old behavior of `SkipCounted` == `false` by setting `CountedLoopTripWidth` to `13` (2 ^ 13 == 8192).

* [InstCombineCalls] Use isKnownNonNullAt() to check nullness of passing ↵Chen Li2015-09-143-2/+26
| | | | | | | | | | | | | | arguments at callsite Summary: This patch replaces isKnownNonNull() with isKnownNonNullAt() when checking nullness of passing arguments at callsite. In this way it can handle cases where the argument does not have nonnull attribute but has a dominating null check from the CFG. It also adds assertions in isKnownNonNull() and isKnownNonNullFromDominatingCondition() to make sure the value checked is pointer type (as defined in LLVM document). These assertions might trip failures in things which are not covered under llvm/test, but fixes should be pretty obvious.

* Revert "[opaque pointer type] Pass GlobalAlias the actual pointer type ↵David Blaikie2015-09-1411-43/+59
| | | | | | | | | | | | | | | | | rather than decomposing it into pointee type + address space" This was a flawed change - it just caused the getElementType call to be deferred until later, when we really need to remove it. Now that the IR for GlobalAliases has been updated, the root cause is addressed that way instead and this change is no longer needed (and in fact gets in the way - because we want to pass the pointee type directly down further). Follow up patches to push this through GlobalValue, bitcode format, etc, will come along soon. This reverts commit 236160. llvm-svn: 247585
* [llvm-mc] Better error handling in ENOENT case + test.Davide Italiano2015-09-142-6/+3
| | | | | | | | | | | | | This is a follow up to r247518. As a general note, I think we could do a much better job testing for error conditions in tools. I already anticipated in a previous mail, but while implementing this I noticed that the code coverage we have for error checking is pretty low. I can arbitrarily remove checks from several tools and the suite still passes. Differential Revision: http://reviews.llvm.org/D12846 llvm-svn: 247582

| | | | | | | | | | | | | | | | GetElementPointers must have the first argument's type compared for structural equivalence. Previously the code erroneously compared the pointer's type, but this code was dead because all pointer types (of the same address space) are the same. The pointee must be compared instead (using the type stored in the GEP, not from the pointer type which will be erased anyway).

* [ARM] Extract shifts out of multiply-by-constantJohn Brawn2015-09-142-50/+293
| | | | | | | | | | | | | | | Turning (op x (mul y k)) into (op x (lsl (mul y k>>n) n)) is beneficial when we can do the lsl as a shifted operand and the resulting multiply constant is simpler to generate. Do this by doing the transformation when trying to select a shifted operand, as that ensures that it actually turns out better (the alternative would be to do it in PreprocessISelDAG, but we don't know for sure there if extracting the shift would allow a shifted operand to be used).
