Is it possible to collect code coverage for a shared library (.so) without using an executable file in LLVM?

I am working with an Android application (APK) that uses JNI and depends on a shared library. I modified the build parameters to include code coverage instrumentation. After running the APK on an Android device and pulling the .profraw files from the device, I merged them into a .profdata file using llvm-profdata merge.

However, I am unable to generate code coverage reports in HTML format because the llvm-cov tool requires an executable file as input, but my target is a shared library (.so file). Since .llvm-cov cannot take a shared library as input directly, I am looking for a way to use the .so file or some workaround to analyze coverage data.

I tried using llvm-cov with the .so file, but I encountered the error that llvm-cov expects an executable file. I also tried to link the shared library with a small executable program and run it locally, but my goal is to avoid creating an additional executable for the sole purpose of generating coverage reports.

➜  test llvm-cov show --instr-profile default.profdata libmap-render.so                                                                          
warning: libmap-render.so: profile data may be out of date - object is newer
error: libmap-render.so: Failed to load coverage: No coverage data found

I was expecting a way to either:

1. Use the .so file directly with llvm-cov.

2. Find a method to link the shared library into a reportable format without the need for an additional executable file.

The solution I'm looking for should allow me to generate an HTML coverage report without needing to create a new executable from the .so file, as I already have the .profraw files from running the APK on the device.
