| | | | | | | | | | | | | | | | | | | | | changes were made to the patch since then. -------- [NewPM] Port Sancov This patch contains a port of SanitizerCoverage to the new pass manager. This one's a bit hefty. Changes: - Split SanitizerCoverageModule into 2 SanitizerCoverage for passing over functions and ModuleSanitizerCoverage for passing over modules. - ModuleSanitizerCoverage exists for adding 2 module level calls to initialization functions but only if there's a function that was instrumented by sancov. - Added legacy and new PM wrapper classes that own instances of the 2 new classes. - Update llvm tests and add clang tests. llvm-svn: 367053

* CodeGen: ensure placeholder instruction for cleanup is createdSaleem Abdulrasool2019-07-251-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A placeholder instruction for use in generation of cleanup code for an initializer list would not be emitted if the base class contained a non-trivial destructor and the class contains no fields of its own. This would be the case when using CTAD to deduce the template arguments for a struct with an overloaded call operator, e.g. ``` template <class... Ts> struct ctad : Ts... {}; template <class... Ts> ctad(Ts...)->ctad<Ts...>; ``` and this class was initialized with a list of lambdas capturing by copy, e.g. ``` ctad c {[s](short){}, [s](long){}}; ``` In a release build the bug would manifest itself as a crash in the SROA pass, however, in a debug build the following assert in CGCleanup.cpp would fail: ``` assert(dominatingIP && "no existing variable and no dominating IP!"); ``` By ensuring that a placeholder instruction is emitted even if there's no fields in the class, neither the assert nor the crash is reproducible.

* Add lifetime categories attributesMatthias Gehre2019-07-252-7/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is the first part of work announced in "[RFC] Adding lifetime analysis to clang" [0], i.e. the addition of the [[gsl::Owner(T)]] and [[gsl::Pointer(T)]] attributes, which will enable user-defined types to participate in the lifetime analysis (which will be part of the next PR). The type `T` here is called "DerefType" in the paper, and denotes the type that an Owner owns and a Pointer points to. E.g. `std::vector<int>` should be annotated with `[[gsl::Owner(int)]]` and a `std::vector<int>::iterator` with `[[gsl::Pointer(int)]]`.

* [ASTImporter] Reorder fields after structure import is finishedGabor Marton2019-07-251-1/+53
| | | | | | | | | | | | | | | | | | | | | | | | | We reorder declarations in RecordDecls because they may have another order in the "to" context than they have in the "from" context. This may happen e.g when we import a class like this: struct declToImport { int a = c + b; int b = 1; int c = 2; }; During the import of `a` we import first the dependencies in sequence, thus the order would be `c`, `b`, `a`. We will get the normal order by first removing the already imported members and then adding them in the order as they apper in the "from" context. Keeping field order is vital because it determines structure layout. Reviewers: a_sidorin, shafik Tags: #clang Differential Revision: https://reviews.llvm.org/D44100 llvm-svn: 366997
* [Clang] New loop pragma vectorize_predicateSjoerd Meijer2019-07-254-3/+48
| | | | | | | | | | | | | | | | | | | This adds a new vectorize predication loop hint: #pragma clang loop vectorize_predicate(enable) that can be used to indicate to the vectoriser that all (load/store) instructions should be predicated (masked). This allows, for example, folding of the remainder loop into the main loop. This patch will be followed up with D64916 and D65197. The former is a refactoring in the loopvectorizer and the groundwork to make tail loop folding a more general concept, and in the latter the actual tail loop folding transformation will be implemented.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: SelectionTree is a RecursiveASTVisitor which processes getSourceRange() for every node. This is a lot of surface area with the AST, as getSourceRange() is specialized for *many* node types. And the resulting SelectionTree depends on the source ranges of many visited nodes, and the order of traversal. Put together, this means we really need a traversal log to debug when we get an unexpected SelectionTree. I've built this ad-hoc a few times, now it's time to check it in.

For `UnknownObjectFormat`, the effect of the action for the `default` case is maintained; otherwise, where `llvm_unreachable` is called, `report_fatal_error` is used instead. Where the `default` case returns a default value, `report_fatal_error` is used for XCOFF as a placeholder. For `Wasm`, the effect of the action for the `default` case in maintained. The code is structured to avoid strongly implying that the `Wasm` case is present for any reason other than to make the switch cover all `ObjectFormatType` enumerator values.

* [clang-scan-deps] Dependency directives source minimizer: handle #pragma onceAlex Lorenz2019-07-181-1/+15
| | | | | | | | | We should re-emit `#pragma once` to ensure the preprocessor will still honor it when running on minimized sources. Differential Revision: https://reviews.llvm.org/D64945 llvm-svn: 366509
* [OPENMP]Fix sharing of threadprivate variables with TLS support.Alexey Bataev2019-07-181-0/+7
| | | | | | | | | If the threadprivate variable is used in the copyin clause on inner parallel directive with TLS support, we capture this variable in all outer OpenMP scopes. It leads to the fact that in all scopes we're working with the original variable, not the threadprivate copies. llvm-svn: 366483
* [RISCV] Hard float ABI supportAlex Bradbury2019-07-183-19/+289
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The RISC-V hard float calling convention requires the frontend to: * Detect cases where, once "flattened", a struct can be passed using int+fp or fp+fp registers under the hard float ABI and coerce to the appropriate type(s) * Track usage of GPRs and FPRs in order to gate the above, and to determine when signext/zeroext attributes must be added to integer scalars This patch attempts to do this in compliance with the documented ABI, and uses ABIArgInfo::CoerceAndExpand in order to do this. @rjmccall, as author of that code I've tagged you as reviewer for initial feedback on my usage. Note that a previous version of the ABI indicated that when passing an int+fp struct using a GPR+FPR, the int would need to be sign or zero-extended appropriately. GCC never did this and the ABI was changed, which makes life easier as ABIArgInfo::CoerceAndExpand can't currently handle sign/zero-extension attributes. Re-landed after backing out 366450 due to missed hunks. Differential Revision: https://reviews.llvm.org/D60456 llvm-svn: 366480
