Well, if the problem is related to the symptom
that I observed with the use of -gsplit-dwarf option
with ccache, then we may be in for a big surprise.
But in that case, the debug information had a file name that
was produced by the initial CPP invocation (*.i), and despite the
#file, #line information, the invocation of gcc using this intermediate
file as input produced gdb debug information using "*.i" file name, and
thus later gdb could not locate source files at all.
Here we are NOT producing such a strange intermediate file, correct?
Hmm, but I think I see some trouble coming up on the horizon :-(
(A few tweaks to the front end of compilers affected may be necessary.)
Hmm to the best of my knowledge, we don't generate the *.i files unless
if you explicitly request them. Is that what you did in that build?
Cheers,
Ehsan
