[LifetimeSafety] Read lifetimebound attribute on implicit 'this' from all redeclarations #176188

usx95 · 2026-01-15T15:44:51Z

Fix handling of lifetimebound attributes on implicit this parameters across function redeclarations.

Previously, the lifetime analysis would miss lifetimebound attributes on implicit this parameters if they were only present on certain redeclarations of a method. This could lead to false negatives in the lifetime safety analysis. This change ensures that if any redeclaration of a method has the attribute, it will be properly detected and used in the analysis.

I can't seem to work around the crash in the earlier attempt #172146.

Reproducer of the original crash:

struct a {
  a &b() [[_Clang::__lifetimebound__]];
};
a &a::b() {}

This only crashes with -target i686-w64-mingw32. bin/clang++ -c a.cpp works fine.
Problematic merging logic:

 // If Old has lifetimebound but New doesn't, add it to New.
  if (OldLBAttr && !NewLBAttr) {
    QualType NewMethodType = New->getType();
    QualType AttributedType =
        S.Context.getAttributedType(OldLBAttr, NewMethodType, NewMethodType);
    TypeLocBuilder TLB;
    TLB.pushFullCopy(NewTSI->getTypeLoc());
    AttributedTypeLoc TyLoc = TLB.push<AttributedTypeLoc>(AttributedType); // Crashes.
    TyLoc.setAttr(OldLBAttr);
    New->setType(AttributedType);
    New->setTypeSourceInfo(TLB.getTypeSourceInfo(S.Context, AttributedType));
  }

Crash

clang++: /REDACTED//llvm-project/clang/lib/Sema/TypeLocBuilder.cpp:89: TypeLoc clang::TypeLocBuilder::pushImpl(QualType, size_t, unsigned int): Assertion `TLast == LastTy && "mismatch between last type and new type's inner type"' failed.

Changes

Fix handling of lifetimebound attributes on implicit this parameters across function redeclarations.

Previously, the lifetime analysis would miss lifetimebound attributes on implicit this parameters if they were only present on certain redeclarations of a method. This could lead to false negatives in the lifetime safety analysis. This change ensures that if any redeclaration of a method has the attribute, it will be properly detected and used in the analysis.

I can't seem to work around the crash in the earlier attempt #172146.

Could you summarize what was the reason for the crash and why was it not possible to work it around?

Added details in the description.

I am fine landing this but would be nice to make merging work in the long term. What are the mismatching types? I wonder where the difference is coming from.

… all redeclarations (llvm#176188) Fix handling of `lifetimebound` attributes on implicit `this` parameters across function redeclarations. Previously, the lifetime analysis would miss `lifetimebound` attributes on implicit `this` parameters if they were only present on certain redeclarations of a method. This could lead to false negatives in the lifetime safety analysis. This change ensures that if any redeclaration of a method has the attribute, it will be properly detected and used in the analysis. I can't seem to work around the crash in the earlier attempt llvm#172146. Reproducer of the original crash: ```cpp struct a { a &b() [[_Clang::__lifetimebound__]]; }; a &a::b() {} ``` This only crashes with `-target i686-w64-mingw32`. `bin/clang++ -c a.cpp` works fine. Problematic merging logic: ```cpp // If Old has lifetimebound but New doesn't, add it to New. if (OldLBAttr && !NewLBAttr) { QualType NewMethodType = New->getType(); QualType AttributedType = S.Context.getAttributedType(OldLBAttr, NewMethodType, NewMethodType); TypeLocBuilder TLB; TLB.pushFullCopy(NewTSI->getTypeLoc()); AttributedTypeLoc TyLoc = TLB.push<AttributedTypeLoc>(AttributedType); // Crashes. TyLoc.setAttr(OldLBAttr); New->setType(AttributedType); New->setTypeSourceInfo(TLB.getTypeSourceInfo(S.Context, AttributedType)); } ``` <details> <summary>Crash</summary> ``` clang++: /REDACTED//llvm-project/clang/lib/Sema/TypeLocBuilder.cpp:89: TypeLoc clang::TypeLocBuilder::pushImpl(QualType, size_t, unsigned int): Assertion `TLast == LastTy && "mismatch between last type and new type's inner type"' failed.
