Bug ID: 48907
Summary: OpenMP compilation broken on non-CUDA system
Product: OpenMP
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: release blocker
Priority: P
Component: Runtime Library
Assignee: unassignedb...@nondot.org
Reporter: tianshilei1...@gmail.com
CC: llvm-bugs@lists.llvm.org
https://reviews.llvm.org/D95466 dropped CUDA to build NVPTX deviceRTL and
enabled it by default. However, the building requires some libraries that are
not available on non-CUDA system by default, which could break the compilation.
