[llvm-dev] Code Coverage Compile Issue LLVM 10

[Aaron via llvm-dev]

Hello,

I recently updated LLVM from version 6.0.0 to 10.0.0.

I see the following issue when I compile an application only with code
coverage compiler options. Thes issue does not appear in any other build
type.

*...:(__llvm_prf_data[__profv__**ZNK4llvm3cfg6UpdateIPNS_**10BasicBlockEE4dumpEv]+0x18):
**undefined reference to `llvm::cfg::Update<llvm::**BasicBlock*>::dump()
const'*

I see this issue only when I compile the app with the following compiler
options:

*-g -O2 -fprofile-instr-generate -fcoverage-mapping*

I don't use any special flags when I build LLVM. I used g++-7 (or
clang++-9) to compile LLVM static libs. The issue does not appear with LLVM
6.0.0.

I included all LLVM libraries in the same order whatever *llvm-config
--libs *outputs.

What lib am I missing? Or is this a known issue?

Thank you,
Aaron
