* [X86] XFormVExtractWithShuffleIntoLoad - handle shuffle mask scalingSimon Pilgrim2019-08-132-16/+29
| | | | | | | | | | If the target shuffle mask is from a wider type, attempt to scale the mask so that the extraction can attempt to peek through. Fixes the regression mentioned in rL368662 Reapplying this as rL368308 had to be reverted as part of rL368660 to revert rL368276 llvm-svn: 368663
* [X86] SimplifyDemandedVectorElts - attempt to recombine target shuffle using ↵Simon Pilgrim2019-08-136-256/+276
| | | | | | | | | | | | | | DemandedElts mask (reapplied) If we don't demand all elements, then attempt to combine to a simpler shuffle. At the moment we can only do this if Depth == 0 as combineX86ShufflesRecursively uses Depth to track whether the shuffle has really changed or not - we'll need to change this before we can properly start merging combineX86ShufflesRecursively into SimplifyDemandedVectorElts. The insertps-combine.ll regression is because XFormVExtractWithShuffleIntoLoad can't see through shuffles of different widths - this will be fixed in a follow-up commit. Reapplying this as rL368307 had to be reverted as part of rL368660 to revert rL368276 llvm-svn: 368662
* [ELF] Don't special case symbolic relocations with 0 addend to ifunc in ↵Fangrui Song2019-08-136-63/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | writable locations Currently the following 3 relocation types do not trigger the creation of a canonical PLT (which changes STT_GNU_IFUNC to STT_FUNC and redirects all references): 1) GOT-generating (`needsGot`) 2) PLT-generating (`needsPlt`) 3) R_ABS with 0 addend in a writable location. This is used for for ifunc function pointers in writable sections such as .data and .toc. This patch deletes case 3) to simplify the R_*_IRELATIVE generating logic added in D57371. Other advantages: * It is guaranteed no more than 1 R_*_IRELATIVE is created for an ifunc. * PPC64: no need to special case ifunc in toc-indirect to toc-relative relaxation. See D65755 The deleted elf::addIRelativeRelocs demonstrates that one-pass scan through relocations makes several optimizations difficult. This is something we can think about in the future.

* [ELF] Simplify handling of exportDynamic and isPreemptibleFangrui Song2019-08-134-23/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In Writer::includeInDynSym(), exportDynamic is used by a Defined with protected or default visibility, to record whether it is required to be exported into .dynsym. It is set when any of the following conditions hold: 1) There is an interposable symbol from a DSO (Undefined or SharedSymbol with default visibility) 2) If -shared or --export-dynamic is specified, any symbol in an object file/bitcode sets this property, unless suppressed by canBeOmittedFromSymbolTable(). 3) --dynamic-list when producing an executable 4) protected symbol from a DSO preempted by copy relocation/canonical PLT when --ignore-{data,function}-address-equality is specified 5) ifunc is exported when -z ifunc-noplt is specified Bullet points 4) and 5) are irrelevant in this patch. Bullet 3) does not play well with 1) and 2). When -shared is specified, exportDynamic of most symbols is true. This makes it incapable to record --dynamic-list marked symbols. We thus have obscure: if (!config->shared) b->exportDynamic = true; else if (b->includeInDynsym()) b->isPreemptible = true; This patch adds another bit `Symbol::inDynamicList` to record 3). We can thus simplify handleDynamicList() by unifying the DSO and executable cases. It also allows us to simplify isPreemptible - now the field is only used in finalizeSections() and later stages.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This was mostly an experiment to assess the feasibility of completely eliminating a problematic implicit conversion case in D61321 in advance of landing that* but it also happens to align with the goal of propagating the use of Register/MCRegister instead of unsigned so I believe it makes sense to commit it. The overall process for eliminating the implicit conversions from Register/MCRegister -> unsigned was to: 1. Add an explicit conversion to support genuinely required conversions to unsigned. For example, using them as an index for IndexedMap. Sadly it's not possible to have an explicit and implicit conversion to the same type and only deprecate the implicit one so I called the explicit conversion get(). 2. Temporarily annotate the implicit conversion to unsigned with LLVM_ATTRIBUTE_DEPRECATED to make them visible 3. Eliminate implicit conversions by propagating Register/MCRegister/ explicit-conversions appropriately 4. Remove the deprecation added in 2. * My conclusion is that it isn't feasible as there's too much code to update in one go.

* [clang] Update isDerivedFrom to support Objective-C classes 🔍Stephane Moore2019-08-126-34/+349
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This change updates `isDerivedFrom` to support Objective-C classes by converting it to a polymorphic matcher. Notes: The matching behavior for Objective-C classes is modeled to match the behavior of `isDerivedFrom` with C++ classes. To that effect, `isDerivedFrom` matches aliased types of derived Objective-C classes, including compatibility aliases. To achieve this, the AST visitor has been updated to map compatibility aliases to their underlying Objective-C class. `isSameOrDerivedFrom` also provides similar behaviors for C++ and Objective-C classes. The behavior that `cxxRecordDecl(isSameOrDerivedFrom("X"))` does not match `class Y {}; typedef Y X;` is mirrored for Objective-C in that `objcInterfaceDecl(isSameOrDerivedFrom("X"))` does not match either `@interface Y @end typedef Y X;` or `@interface Y @end @compatibility_alias X Y;`.
