The changes to tablegen made by https://github.com/llvm/llvm-project/pull/76825 result in `StmtClass::lastStmtConstant` changing from `StmtClass::WhileStmtClass` to `StmtClass::GCCAsmStmtClass`. Since `CFG::BuildOptions::alwaysAdd` is never called with a `WhileStmt`, this has flown under the radar until now. >From a06f149e584376aefd7b4f88e0b6db23963b367c Mon Sep 17 00:00:00 2001 From: Krystian Stasiowski <sdkryst...@gmail.com> Date: Sat, 6 Jan 2024 07:26:06 -0500 Subject: [PATCH] [Clang][NFC] Fix out-of-bounds access --- clang/include/clang/Analysis/CFG.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/clang/include/clang/Analysis/CFG.h b/clang/include/clang/Analysis/CFG.h index 67383bb316d318..ec10768f600a2a 100644 --- a/clang/include/clang/Analysis/CFG.h +++ b/clang/include/clang/Analysis/CFG.h @@ -1215,7 +1215,7 @@ class CFG { //===--------------------------------------------------------------------===// class BuildOptions { - std::bitset<Stmt::lastStmtConstant> alwaysAddMask; + std::bitset<Stmt::lastStmtConstant + 1> alwaysAddMask; public: using ForcedBlkExprs = llvm::DenseMap<const Stmt *, const CFGBlock *>; _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
