This PR uses the VFS to create the OpenMP target entry instead of going straight to the real file system. This matches the behavior of other input files of the compiler. >From d149b833da496cb2749410b1692789c1075819f1 Mon Sep 17 00:00:00 2001 From: Jan Svoboda <[email protected]> Date: Thu, 25 Sep 2025 15:57:31 -0700 Subject: [PATCH] [clang] Use the VFS to create the OpenMP region entry ID --- clang/lib/CodeGen/CGOpenMPRuntime.cpp | 3 ++- llvm/include/llvm/Frontend/OpenMP/OMPIRBuilder.h | 2 +- llvm/lib/Frontend/OpenMP/OMPIRBuilder.cpp | 14 ++++++++------ 3 files changed, 11 insertions(+), 8 deletions(-) diff --git a/clang/lib/CodeGen/CGOpenMPRuntime.cpp b/clang/lib/CodeGen/CGOpenMPRuntime.cpp index c90e1a487daf9..9004296a7e453 100644 --- a/clang/lib/CodeGen/CGOpenMPRuntime.cpp +++ b/clang/lib/CodeGen/CGOpenMPRuntime.cpp @@ -1550,7 +1550,8 @@ static llvm::TargetRegionEntryInfo getEntryInfoFromPresumedLoc( return std::pair<std::string, uint64_t>(PLoc.getFilename(), PLoc.getLine()); }; - return OMPBuilder.getTargetEntryUniqueInfo(FileInfoCallBack, ParentName); + return OMPBuilder.getTargetEntryUniqueInfo(FileInfoCallBack, + *CGM.getFileSystem(), ParentName); } ConstantAddress CGOpenMPRuntime::getAddrOfDeclareTargetVar(const VarDecl *VD) { diff --git a/llvm/include/llvm/Frontend/OpenMP/OMPIRBuilder.h b/llvm/include/llvm/Frontend/OpenMP/OMPIRBuilder.h index f43ef932e965a..bfe1c8090acfe 100644 --- a/llvm/include/llvm/Frontend/OpenMP/OMPIRBuilder.h +++ b/llvm/include/llvm/Frontend/OpenMP/OMPIRBuilder.h @@ -1402,7 +1402,7 @@ class OpenMPIRBuilder { /// any.
