This PR uses the VFS to get the unique file ID when printing externalized decls in CUDA instead of going straight to the real file system. This matches the behavior of other input files of the compiler. >From e0d452e9cccb10cf1f1404ed6b835de31af8c9e9 Mon Sep 17 00:00:00 2001 From: Jan Svoboda <[email protected]> Date: Fri, 26 Sep 2025 12:37:37 -0700 Subject: [PATCH] [clang] Use the VFS to get the unique file ID --- clang/lib/CodeGen/CodeGenModule.cpp | 13 +++++++++---- 1 file changed, 9 insertions(+), 4 deletions(-) diff --git a/clang/lib/CodeGen/CodeGenModule.cpp b/clang/lib/CodeGen/CodeGenModule.cpp index 875f06b53f53d..f6f7f22a09004 100644 --- a/clang/lib/CodeGen/CodeGenModule.cpp +++ b/clang/lib/CodeGen/CodeGenModule.cpp @@ -8172,12 +8172,17 @@ void CodeGenModule::printPostfixForExternalizedDecl(llvm::raw_ostream &OS, // Get the UniqueID for the file containing the decl. llvm::sys::fs::UniqueID ID; - if (llvm::sys::fs::getUniqueID(PLoc.getFilename(), ID)) { + auto Status = FS->status(PLoc.getFilename()); + if (!Status) { PLoc = SM.getPresumedLoc(D->getLocation(), /*UseLineDirectives=*/false); assert(PLoc.isValid() && "Source location is expected to be valid."); - if (auto EC = llvm::sys::fs::getUniqueID(PLoc.getFilename(), ID)) - SM.getDiagnostics().Report(diag::err_cannot_open_file) - << PLoc.getFilename() << EC.message(); + Status = FS->status(PLoc.getFilename()); + } + if (!Status) { + SM.getDiagnostics().Report(diag::err_cannot_open_file) + << PLoc.getFilename() << Status.getError().message(); + } else { + ID = Status->getUniqueID(); } OS << llvm::format("%x", ID.getFile()) << llvm::format("%x", ID.getDevice()) << "_" << llvm::utohexstr(Result.low(), /*LowerCase=*/true, /*Width=*/8); _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
