In order to get the module: and mmap: lines from DSOMarkupPrinter::printDSOMarkup, there must be an NT_GNU_BUILD_ID note in the binary. However, this is not something that is guaranteed, as different platforms have different defaults, and even within that you can configure it (e.g. ENABLE_LINKER_BUILD_ID in the case of Clang). This test is therefore very fragile (e.g. it breaks on FreeBSD when built with Clang+LLD, as (a) ENABLE_LINKER_BUILD_ID defaults to OFF (b) there is no code in FreeBSD.cpp to pass --build-id if ENABLE_LINKER_BUILD_ID is set (c) LLD defaults to no build ID if no option is passed) and I believe should be disabled or marked flaky somehow until it's able to accurately capture the requirements from its environments.
Cc @mysterymath as the author of the test.
