If someone figures out how to generate code coverage data on

that, I personally don't have any plans to work further on code
coverage. If you want to take a shot at generating reports yourself, one
possibility is lcov, a graphical frontend to gcov. I believe sledru
and/or jcranmer may also have some scripts for doing it.
We run tests on a dozen platforms and you consider Windows/OS X/Linux 64
sufficient? :-)
Actually, as far as I know:
1. Linux-32 works exactly the same as Linux-64 (export
CFLAGS/CXXFLAGS/LDFLAGS/HOST_LDFLAGS='--coverage' in the mozconfig)
2. Android should work the same, but it needs modification to harnesses
to extract the code-coverage to/from the device.
3. OS X builds use clang, which should interoperate with gcc's method,
but it does cause either a link error (in opt) or a runtime loader issue
(in debug). I think a newer version of clang would fix the issues, but
I've been unable to figure out how to test a newer version of clang on
the try servers.
I'm the one who has the scripts to generate the data, and I will
probably look into modifying my setup to accommodate linux64-cc.
