SID support for gcov?

SID support for gcov?

[Dave Brolley]

Can gcov be used with SID? From what I've read about gcov it doesn't 
seem like any special SID support would be necessary. It seems like all 
the needed support is done at compile time and by runtime code, however 
executing a simple program after compiling it with -dprofile-arcs and 
-ftest-coverage didn't produce any .da files. Perhaps the runtime code 
doesn't use any of the supported syscalls?

Any help would be appreciated.

Thanks,
Dave

You're right--the instrumented code relies on runtime support on the
target for doing things like opening and writing the .da files on the
host.  Does your gloss/monitor support this?

My recollection is that I tested this a couple of years ago and it
worked (at least for the target I worked on).
