(#118005) Right now fields with macro declarations break the tool: ``` struct Foo { Mutex mu; int x GUARDED_BY(mu); int y; }; ``` reordered by mu,y,x yields: ``` struct Foo { Mutex mu; int y GUARDED_BY(mu); int x; }; ``` Added: clang-tools-extra/test/clang-reorder-fields/FieldAnnotationsInMacros.cpp Modified: clang-tools-extra/clang-reorder-fields/ReorderFieldsAction.cpp Removed: ################################################################################ diff --git a/clang-tools-extra/clang-reorder-fields/ReorderFieldsAction.cpp b/clang-tools-extra/clang-reorder-fields/ReorderFieldsAction.cpp index 346437e20322e6..dc3a3b6211b7e4 100644 --- a/clang-tools-extra/clang-reorder-fields/ReorderFieldsAction.cpp +++ b/clang-tools-extra/clang-reorder-fields/ReorderFieldsAction.cpp @@ -116,6 +116,28 @@ findMembersUsedInInitExpr(const CXXCtorInitializer *Initializer, return Results; } +/// Returns the full source range for the field declaration up to (not +/// including) the trailing semicolumn, including potential macro invocations, +/// e.g. `int a GUARDED_BY(mu);`. +static SourceRange getFullFieldSourceRange(const FieldDecl &Field, + const ASTContext &Context) { + SourceRange Range = Field.getSourceRange(); + SourceLocation End = Range.getEnd(); + const SourceManager &SM = Context.getSourceManager(); + const LangOptions &LangOpts = Context.getLangOpts(); + while (true) { + std::optional<Token> CurrentToken = Lexer::findNextToken(End, SM, LangOpts); + + if (!CurrentToken || CurrentToken->is(tok::semi)) + break; + + if (CurrentToken->is(tok::eof)) + return Range; // Something is wrong, return the original range. + End = CurrentToken->getLastLoc(); + } + return SourceRange(Range.getBegin(), End); +} + /// Reorders fields in the definition of a struct/class. /// /// At the moment reordering of fields with @@ -145,9 +167,10 @@ static bool reorderFieldsInDefinition( const auto FieldIndex = Field->getFieldIndex(); if (FieldIndex == NewFieldsOrder[FieldIndex]) continue; - addReplacement(Field->getSourceRange(), - Fields[NewFieldsOrder[FieldIndex]]->getSourceRange(), - Context, Replacements); + addReplacement( + getFullFieldSourceRange(*Field, Context), + getFullFieldSourceRange(*Fields[NewFieldsOrder[FieldIndex]], Context), + Context, Replacements); } return true; } diff --git a/clang-tools-extra/test/clang-reorder-fields/FieldAnnotationsInMacros.cpp b/clang-tools-extra/test/clang-reorder-fields/FieldAnnotationsInMacros.cpp new file mode 100644 index 00000000000000..aedec9556aa55a --- /dev/null +++ b/clang-tools-extra/test/clang-reorder-fields/FieldAnnotationsInMacros.cpp @@ -0,0 +1,9 @@ +// RUN: clang-reorder-fields -record-name Foo -fields-order y,x %s -- | FileCheck %s + +#define GUARDED_BY(x) __attribute__((guarded_by(x))) + +class Foo { + int x GUARDED_BY(x); // CHECK: {{^ int y;}} + int y; // CHECK-NEXT: {{^ int x GUARDED_BY\(x\);}} +}; + _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
