            Bug ID: 43196
           Summary: Please backport r369310 to 9.x
           Product: new-bugs
           Version: 9.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: new bugs

While the commit in question is marked as 'NFC', without it the following tests
hang for me on NetBSD:

    LLVM :: ExecutionEngine/MCJIT/eh-lg-pic.ll
    LLVM :: ExecutionEngine/MCJIT/eh.ll
    LLVM :: ExecutionEngine/MCJIT/multi-module-eh-a.ll
    LLVM :: ExecutionEngine/OrcMCJIT/eh-lg-pic.ll
    LLVM :: ExecutionEngine/OrcMCJIT/eh.ll
    LLVM :: ExecutionEngine/OrcMCJIT/multi-module-eh-a.ll

To be honest, I don't know how it is relevant.  It is possible that the linking
is necessary for reasons other than those listed in the commit message.

    [cmake] Link in LLVMPasses due to dependency by LLVMOrcJIT; NFC

    Summary:
    rL367756 (f5c40cb) increases the dependency of LLVMOrcJIT on LLVMPasses.    
    In particular, symbols defined in LLVMPasses that are referenced by the     
    destructor of `PassBuilder` are now referenced by LLVMOrcJIT through
    `Speculation.cpp.o`.

    We believe that referencing symbols defined in LLVMPasses in the
    destructor of `PassBuilder` is valid, and that adding to the set of such    
    symbols is legitimate. To support such cases, this patch adds LLVMPasses    
    to the set of libraries being linked when linking in LLVMOrcJIT causes      
    such symbols from LLVMPasses to be referenced.
