local qc="[c++20] Implement semantic restrictions for C++20 designated\ninitializers.\n\nThis has some interesting interactions with our existing extensions to\nsupport C99 designated initializers as an extension in C++. Those are\nresolved as follows:\n\n * We continue to permit the full breadth of C99 designated initializers\n in C++, with the exception that we disallow a partial overwrite of an\n initializer with a non-trivially-destructible type. (Full overwrite\n is OK, because we won\'t run the first initializer at all.)\n\n * The C99 extensions are disallowed in SFINAE contexts and during\n overload resolution, where they could change the meaning of valid\n programs.\n\n * C++20 disallows reordering of initializers. We only check for that for\n the simple cases that the C++20 rules permit (designators of the form\n \'.field_name =\' and continue to allow reordering in other cases).\n It would be nice to improve this behavior in future.\n\n * All C99 designated initializer extensions produce a warning by\n default in C++20 mode. People are going to learn the C++ rules based\n on what Clang diagnoses, so it\'s important we diagnose these properly\n by default.\n\n * In C++ <= 17, we apply the C++20 rules rather than the C99 rules, and\n so still diagnose C99 extensions as described above. We continue to\n accept designated C++20-compatible initializers in C++ <= 17 silently\n by default (but naturally still reject under -pedantic-errors).\n\nThis is not a complete implementation of P0329R4. In particular, that\npaper introduces new non-C99-compatible syntax { .field { init } }, and\nwe do not support that yet.\n\nThis is based on a previous patch by Don Hinton, though I\'ve made\nsubstantial changes when addressing the above interactions.\n\nDifferential Revision: https://reviews.llvm.org/D59754\n\nllvm-svn: 370544";

From\nthese definitions we generate the enum classes `TraitSet`,\n`TraitSelector`, and `TraitProperty` as well as conversion and helper\nfunctions in `llvm/lib/Frontend/OpenMP/OMPContext.{h,cpp}`.\n\nThe above enum classes are used in the parser, sema, and the AST\nattribute. The latter is not a collection of multiple primitive variant\narguments that contain encodings via numbers and strings but instead a\ntree that mirrors the `match` clause (see `struct OpenMPTraitInfo`).\n\nThe changes to the parser make it more forgiving when wrong syntax is\nread and they also resulted in more specialized diagnostics. The tests\nare updated and the core issues are detected as before. Here and\nelsewhere this patch tries to be generic, thus we do not distinguish\nwhat selector set, selector, or property is parsed except if they do\nbehave exceptionally, as for example `user={condition(EXPR)}` does.\n\nThe sema logic changed in two ways: First, the OMPDeclareVariantAttr\nrepresentation changed, as mentioned above, and the sema was adjusted to\nwork with the new `OpenMPTraitInfo`. Second, the matching and scoring\nlogic moved into `OMPContext.{h,cpp}`. It is implemented on a flat\nrepresentation of the `match` clause that is not tied to clang.\n`OpenMPTraitInfo` provides a method to generate this flat structure (see\n`struct VariantMatchInfo`) by computing integer score values and boolean\nuser conditions from the `clang::Expr` we keep for them.\n\nThe OpenMP context is now an explicit object (see `struct OMPContext`).\nThis is in anticipation of construct traits that need to be tracked. The\nOpenMP context, as well as the `VariantMatchInfo`, are basically made up\nof a set of active or respectively required traits, e.g., \'host\', and an\nordered container of constructs which allows duplication. Matching and\nscoring is kept as generic as possible to allow easy extension in the\nfuture.\n\n---\n\nTest changes:\n\nThe messages checked in `OpenMP/declare_variant_messages.{c,cpp}` have\nbeen auto generated to match the new warnings and notes of the parser.\nThe \"subset\" checks were reversed causing the wrong version to be\npicked. The tests have been adjusted to correct this.\nWe do not print scores if the user did not provide one.\nWe print spaces to make lists in the `match` clause more legible.\n\nReviewers: kiranchandramohan, ABataev, RaviNarayanaswamy, gtbercea, grokos, sdmitriev, JonChesterfield, hfinkel, fghanim\n\nSubscribers: merge_guards_bot, rampitec, mgorny, hiraditya, aheejin, fedor.sergeev, simoncook, bollu, guansong, dexonsmith, jfb, s.egerton, llvm-commits, cfe-commits\n\nTags: #clang, #llvm\n\nDifferential Revision: https://reviews.llvm.org/D71830"},

To avoid having to implement the polymorphism\nwith several layers of nested _Generic and make error reporting\nhideous, I want to make all the user-facing intrinsics correspond\ndirectly to clang builtins, so that after clang resolves\n__attribute__((overloadable)) polymorphism it\'s already holding the\nright BuiltinID for the intrinsic it selected.\n\nHowever, this commit itself just introduces the new attribute, and\ndoesn\'t use it for anything.\n\nTo avoid unanticipated side effects if this attribute is used to make\naliases to other builtins, there\'s a restriction mechanism: only\n(BuiltinID, alias) pairs that are approved by the function\nArmMveAliasValid() will be permitted.

Given:\n\n #define F(a,...) a #__VA_OPT__(a ## a) a ## __VA_OPT__(__VA_ARGS__)\n\n - The call F(,) Does not supply any tokens for the variadic arguments and hence VA_OPT behaves as a placeholder.\n - When expanding VA_OPT (for e.g. F(,1) token pasting occurs eagerly within its contents if the contents need to be stringified.\n - A hash or a hashhash prior to VA_OPT does not inhibit expansion of arguments if they are the first token within VA_OPT.\n - When a variadic argument is supplied, argument substitution occurs within the contents as does stringification - and these resulting tokens are inserted back into the macro expansions token stream just prior to the entire stream being rescanned and concatenated.\n\nSee wg21.link/P0306 for further details on the feature.\n\n\nAcknowledgment: This patch would have been poorer if not for Richard Smith\'s usual thoughtful analysis and feedback.\nllvm-svn: 315840"},

From\nthese definitions we generate the enum classes `TraitSet`,\n`TraitSelector`, and `TraitProperty` as well as conversion and helper\nfunctions in `llvm/lib/Frontend/OpenMP/OMPContext.{h,cpp}`.\n\nThe above enum classes are used in the parser, sema, and the AST\nattribute. The latter is not a collection of multiple primitive variant\narguments that contain encodings via numbers and strings but instead a\ntree that mirrors the `match` clause (see `struct OpenMPTraitInfo`).\n\nThe changes to the parser make it more forgiving when wrong syntax is\nread and they also resulted in more specialized diagnostics. The tests\nare updated and the core issues are detected as before. Here and\nelsewhere this patch tries to be generic, thus we do not distinguish\nwhat selector set, selector, or property is parsed except if they do\nbehave exceptionally, as for example `user={condition(EXPR)}` does.\n\nThe sema logic changed in two ways: First, the OMPDeclareVariantAttr\nrepresentation changed, as mentioned above, and the sema was adjusted to\nwork with the new `OpenMPTraitInfo`. Second, the matching and scoring\nlogic moved into `OMPContext.{h,cpp}`. It is implemented on a flat\nrepresentation of the `match` clause that is not tied to clang.\n`OpenMPTraitInfo` provides a method to generate this flat structure (see\n`struct VariantMatchInfo`) by computing integer score values and boolean\nuser conditions from the `clang::Expr` we keep for them.\n\nThe OpenMP context is now an explicit object (see `struct OMPContext`).\nThis is in anticipation of construct traits that need to be tracked. The\nOpenMP context, as well as the `VariantMatchInfo`, are basically made up\nof a set of active or respectively required traits, e.g., \'host\', and an\nordered container of constructs which allows duplication. Matching and\nscoring is kept as generic as possible to allow easy extension in the\nfuture.\n\n---\n\nTest changes:\n\nThe messages checked in `OpenMP/declare_variant_messages.{c,cpp}` have\nbeen auto generated to match the new warnings and notes of the parser.\nThe \"subset\" checks were reversed causing the wrong version to be\npicked. The tests have been adjusted to correct this.\nWe do not print scores if the user did not provide one.\nWe print spaces to make lists in the `match` clause more legible.\n\nReviewers: kiranchandramohan, ABataev, RaviNarayanaswamy, gtbercea, grokos, sdmitriev, JonChesterfield, hfinkel, fghanim\n\nSubscribers: merge_guards_bot, rampitec, mgorny, hiraditya, aheejin, fedor.sergeev, simoncook, bollu, guansong, dexonsmith, jfb, s.egerton, llvm-commits, cfe-commits\n\nTags: #clang, #llvm\n\nDifferential Revision: https://reviews.llvm.org/D71830"},
