We are using the LLVM linker (https://lld.llvm.org/) in Clang. LLVM linker errors are not detected by the clang tool in warnings-ng-plugin. Such an error might look as follows:

ld.lld-15: error: cannot open xyz: No such file or directory

It seems that there is no appropriate parser for such errors in https://github.com/jenkinsci/analysis-model. For comparison, Gcc4LinkerParser successfully detects ld errors when we use the ld linker in GCC instead, plus the gcc tool in warnings-ng-plugin.
