6c75ab5f - Introduce _BitInt, deprecate _ExtInt

Mon, 06 Dec 2021 17:46:54 +0000

Introduce _BitInt, deprecate _ExtIntWG14 adopted the _ExtInt feature from Clang for C23, but renamed thetype to be _BitInt. This patch does the vast majority of the work torename _ExtInt to _BitInt, which accounts for most of its size. The newtype is exposed in older C modes and all C++ modes as a conformingextension. However, there are functional changes worth calling out:* Deprecates _ExtInt with a fix-it to help users migrate to _BitInt.* Updates the mangling for the type.* Updates the documentation and adds a release note to warn users whatis going on.* Adds new diagnostics for use of _BitInt to call out when it's used asa Clang extension or as a pre-C23 compatibility concern.* Adds new tests for the new diagnostic behaviors.I want to call out the ABI break specifically. We do not believe thatthis break will cause a significant imposition for early adopters ofthe feature, and so this is being done as a full break. If it turns outthere are critical uses where recompilation is not an option for somereason, we can consider using ABI tags to ease the transition.

da986511 - Revert "DR2064: decltype(E) is only a dependent type if E is type-dependent, not

Revert "DR2064: decltype(E) is only a dependent type if E is type-dependent, notif E is merely instantiation-dependent."This change leaves us unable to distinguish between different functiontemplates that differ in only instantiation-dependent ways, for exampletemplate decltype(int(T())) f();template decltype(int(T(0))) f();We'll need substantially better support for types that areinstantiation-dependent but not dependent before we can go ahead withthis change.This reverts commit e3065ce238475ec202c707f4c58d90df171626ca.

d28267f9 - [AST][RecoveryExpr] Add error-bit to NestNameSpecifierDependence and TemplateNameDependence.

[AST][RecoveryExpr] Add error-bit to NestNameSpecifierDependence and TemplateNameDependence.Summary:We might lose the error-bit if the error-bit goes through the code path"error type/expr" -> "error template argument" -> "nested name specifier" ->... -> "template Specialization type"Template name also needs this, as a template can be nested intoan error specifier, e.g. templateName apply in`TC(Foo, int()))>::template apply`Reviewers: sammccallSubscribers: cfe-commitsTags: #clangDifferential Revision: https://reviews.llvm.org/D82526 List of files: /llvm-project-15.0.7/clang/test/Sema/invalid-bitwidth-expr.mm

[AST][RecoveryExpr] Make DeduceAutoType fail if the auto is deduced from recovery exprs.Summary:With recovery-ast, we will get an undeduced `auto` return type for"auto foo()->undef()" function declaration, the function decl still keepsvalid, it is dangerous, and breaks assumptions in clang, and leads crashes.This patch invalidates these functions, if we deduce autos from thereturn rexpression, which is similar to auto VarDecl.Subscribers: cfe-commitsTags: #clangDifferential Revision: https://reviews.llvm.org/D80221 List of files: /llvm-project-15.0.7/clang/test/Sema/invalid-bitwidth-expr.mm
