Hi,

I have a backend  and I would like to have a systematic way to know if
my testsuite covers all the define_insn and define_expand rules in my
md file.

What's the best way to achieve this?

I initially thought I could use gcov to check the coverage of the code
that is generated from the md file but I would like to know if there
is any better way to do this since I doubt I am the only one wishing
to do this.

Cheers,
