* [MSVC] Recognize `static_assert` keyword in C and C++98Reid Kleckner2019-02-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The main effect is that clang now accepts the following conforming C11 code with MSVC headers: #include <assert.h> static_assert(1, "true"); This is a non-conforming extension (the keyword is outside the implementer's namespace), so it is placed under -fms-compatibility instead of -fms-extensions like most MSVC-specific keyword extensions. Normally, in C11, the compiler is supposed to provide the _Static_assert keyword, and assert.h should define static_assert to _Static_assert. However, that is not what MSVC does, and MSVC doesn't even provide _Static_assert. This also has the less important side effect of enabling static_assert in C++98 mode with -fms-compatibility. It's exceptionally difficult to use modern MSVC headers without C++14 even, so this is relatively unimportant. Fixes PR26672 Patch by Andrey Bokhanko!

* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@351636 91177308-0d34-0410-b5e6-96231b3b80d8
* [Basic] Cleanups in IdentifierInfo following the removal of PTHBruno Ricci2018-12-051-22/+0
| | | | | | | | | | | | | | | | | | | The Entry pointer in IdentifierInfo was only null for IdentifierInfo created from a PTH. Now that PTH support has been removed we can remove some PTH specific code in IdentifierInfo::getLength and IdentifierInfo::getNameStart. Also make the constructor of IdentifierInfo private to make sure that they are only created by IdentifierTable, and move it to the header so that it can be inlined in IdentifierTable::get and IdentifierTable::getOwn.

* Fix clang -Wimplicit-fallthrough warnings across llvm, NFCReid Kleckner2018-11-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch should not introduce any behavior changes. It consists of mostly one of two changes: 1. Replacing fall through comments with the LLVM_FALLTHROUGH macro 2. Inserting 'break' before falling through into a case block consisting of only 'break'. We were already using this warning with GCC, but its warning behaves slightly differently. In this patch, the following differences are relevant: 1. GCC recognizes comments that say "fall through" as annotations, clang doesn't 2. GCC doesn't warn on "case N: foo(); default: break;", clang does 3. GCC doesn't warn when the case contains a switch, but falls through the outer case. I will enable the warning separately in a follow-up patch so that it can be cleanly reverted if necessary.

* [SystemZ] Actually enable -mzvector keywordsUlrich Weigand2018-10-161-0/+1
| | | | | | | | | | | | | | | | It appears when initially committing the support for the IBM Z vector extension language, one critical line was lost, causing the specific keywords __vector, __bool, and vec_step to not actually be enabled. (Note that this does not affect "vector" and "bool"!) Unfortunately, this was not caught by any tests either. (All existing Z vector tests just use the regular "vector" and "bool" keywords ...)

* [AST] Various optimizations + refactoring in DeclarationName(Table)Bruno Ricci2018-09-211-15/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Introduce the following optimizations in DeclarationName(Table): 1. Store common kinds inline in DeclarationName instead of DeclarationNameExtra. Currently the kind of C++ constructor, destructor, conversion function and overloaded operator names is stored in DeclarationNameExtra. Instead store it inline in DeclarationName. To do this align IdentifierInfo, CXXSpecialName, DeclarationNameExtra and CXXOperatorIdName to 8 bytes so that we can use the lower 3 bits of DeclarationName::Ptr. This is already the case on 64 bits archs anyway. This also allow us to remove DeclarationNameExtra from CXXSpecialName and CXXOperatorIdName, which shave off a pointer from CXXSpecialName. 2. Synchronize the enumerations DeclarationName::NameKind, DeclarationName::StoredNameKind and Selector::IdentifierInfoFlag. This makes DeclarationName::getNameKind much more efficient since we can replace the switch table by a single comparison and an addition. 3. Put the overloaded operator names inline in DeclarationNameTable to remove an indirection. This increase the size of DeclarationNameTable a little bit but this is not important since it is only used in ASTContext, and never copied nor moved from. This also get rid of the last dynamic allocation in DeclarationNameTable. Altogether these optimizations cut the run time of parsing all of Boost by about 0.8%. While we are at it, do the following NFC modifications: 1. Put the internal classes CXXSpecialName, CXXDeductionGuideNameExtra, CXXOperatorIdName, CXXLiteralOperatorIdName and DeclarationNameExtra in a namespace detail since these classes are only meant to be used by DeclarationName and DeclarationNameTable. Make this more explicit by making the members of these classes private and friending DeclarationName(Table). 2. Make DeclarationName::getFETokenInfo a non-template since every users are using it to get a void *. It was supposed to be used with a type to avoid a subsequent static_cast. 3. Change the internal functions DeclarationName::getAs* to castAs* since when we use them we already know the correct kind. This has no external impact since all of these are private.

This is also supported by this sentence from performSelector documentation: "The method should not have a significant return value and should take a single argument of type id, or no arguments".

These all seem to have useful properties and correlations to document, in one case we even had it in a comment but now it will also be an assert. This should prevent PVS-Studio from incorrectly claiming that there are a bunch of potential bugs here. But I feel really strongly that the PVS-Studio warnings that pointed at this code have a far too high false-positive rate to be entirely useful. These are just places where there did seem to be a useful invariant to document and verify with an assert. Several other places in the code were already correct and already have perfectly clear code documenting and validating their invariants, but still ran afoul of PVS-Studio. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@285985 91177308-0d34-0410-b5e6-96231b3b80d8

There is a desire to support __declspec in Playstation code, and possibly other environments.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The z13 vector facility has an associated language extension, closely modeled on AltiVec/VSX. The main differences are: - vector long, vector float and vector pixel are not supported - vector long long and vector double are supported (like VSX) - comparison operators return a vector rather than a scalar integer - shift operators behave like the OpenCL shift operators - vector bool is only supported as argument to certain operators; some operators allow mixing a bool with a non-bool vector This patch adds clang support for the extension. It is closely modelled on the AltiVec support. Similarly to the -faltivec option, there's a new -fzvector option to enable the extensions (as well as an -mzvector alias for compatibility with GCC). There's also a separate LangOpt. The extension as implemented here is intended to be compatible with the -mzvector extension recently implemented by GCC. Based on a patch by Richard Sandiford.

* [Concepts] lex keywords: concept and requiresHubert Tong2015-06-051-1/+3
| | | | | | | | | | | | | | | | | | | | | | Summary: This patch enables lexing of `concept` and `requires` as keywords. Further changes which add messages for future keyword compat are to follow. Test Plan: Testing of C++14 + Concepts TS mode is added to `test/Lexer/keywords_test.cpp`, which expects that the new keywords are enabled under said mode.

Note: __declspec is also temporarily enabled when compiling for a CUDA target because there are implementation details relying on __declspec(property) support currently. When those details change, __declspec should be disabled for CUDA targets. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@238238 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | This, in preparation for the introduction of more new keywords in the implementation of the C++ language, generalizes the support for future keyword compat diagnostics (e.g., diag::warn_cxx11_keyword) by extending the applicability of the relevant property in IdentifierTable with appropriate renaming.

* Emit warning if define or undef reserved identifier or keyword.Serge Pavlov2014-12-021-2/+27
| | | | | | | | | | | | | | | | | | | | | | Summary: This change implements warnings if macro name is identical to a keyword or reserved identifier. The warnings are different depending on the "danger" of the operation. Defining macro that replaces a keyword is on by default. Other cases produce warning that is off by default but can be turned on using option -Wreserved-id-macro. This change fixes PR11488.
