That works:
With this code:
typedef int zzz;
zzz z;
gdb:
(gdb) whatis z
type = zzz
(gdb) whatis (zzz)0
type = zzz
(gdb) whatis zzz
type = int
and at least
make check TESTS="*/whatis*.exp */*ptype*.exp"
passes, which is promising.
Haven't tried this against a printer, but I think
it should start working.
We may need OP_SCOPE too.
I'll try running this against the full gdb testsuite,
and write some test.
Thanks,
