* Revert r247684 - Replace Triple with a new TargetTuple ...Daniel Sanders2015-09-15100-754/+407

* Replace Triple with a new TargetTuple in MCTargetDesc/* and related. NFC.Daniel Sanders2015-09-15100-407/+754
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PlaceSafepoints] Make the width of a counted loop settable.Sanjoy Das2015-09-151-18/+11
| | | | | | | | | | | | | | | | | | 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 Li2015-09-142-2/+6
| | | | | | | | | | | | | | 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 Blaikie2015-09-149-32/+46
| | | | | | | | | | | | | | | | | 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

* [MergeFuncs] Fix bug in merging GetElementPointersJF Bastien2015-09-141-2/+2
| | | | | | | | | | | | | | | | 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 Brawn2015-09-141-19/+111
| | | | | | | | | | | | | | | 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).

* [PM] Port SROA to the new pass manager.Chandler Carruth2015-09-125-409/+346
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In some ways this is a very boring port to the new pass manager as there are no interesting analyses or dependencies or other oddities. However, this does introduce the first good example of a transformation pass with non-trivial state porting to the new pass manager. I've tried to carve out patterns here to replicate elsewhere, and would appreciate comments on whether folks like these patterns: - A common need in the new pass manager is to effectively lift the pass class and some of its state into a public header file. Prior to this, LLVM used anonymous namespaces to provide "module private" types and utilities, but that doesn't scale to cases where a public header file is needed and the new pass manager will exacerbate that. The pattern I've adopted here is to use the namespace-cased-name of the core pass (what would be a module if we had them) as a module-private namespace. Then utility and other code can be declared and defined in this namespace. At some point in the future, we could even have (conditionally compiled) code that used modules features when available to do the same basic thing. - I've split the actual pass run method in two in order to expose a private method usable by the old pass manager to wrap the new class with a minimum of duplicated code. I actually looked at a bunch of ways to automate or generate these, but they are all quite terrible IMO. The fundamental need is to extract the set of analyses which need to cross this interface boundary, and that will end up being too unpredictable to effectively encapsulate IMO. This is also a relatively small amount of boiler plate that will live a relatively short time, so I'm not too worried about the fact that it is boiler plate. The rest of the patch is totally boring but results in a massive diff (sorry). It just moves code around and removes or adds qualifiers to reflect the new name and nesting structure.
