Hello,
In JDK-8073021 I added support for compiling with gcov support for
native code coverage. When trying to use this it was discovered that the
file layout in the new symbols image need to exactly match the layout of
the .gcno files in the build directory. Otherwise the runtime data files
created by gcov will not match properly.
I originally tried to tidy up the layout in the symbols file into:
symbols/gcov/hotspot/{client,server}/*.gcno
symbols/gcov/jdk/$(module)/$(lib)/*.gcno
What we actually need is the (internal) layout of the intermediate build
results:
symbols/gcov/hotspot/linux_amd64_compiler2/product/*.gcno
symbols/gcov/support/native/$(module)/$(lib)/*.gcno
Our internal layout for intermediate build results is not something we
want to export as an API, but in this case, the file layout just has to
match the paths that get encoded into the binaries.
