--- Comment #12 from Tom Tromey <tromey at gcc dot gnu.org> ---
I noticed this patch today and tried it out on my current
test case, which uses -Wc++-compat... unfortunately it
still fails.
Test code:
extern void xfer (int, int, unsigned char *);
void call (int x, int y, void *arg)
{
xfer (x, y, arg);
}
barimba. gcc --syntax-only -Wc++-compat /tmp/r.c
/tmp/r.c: In function ‘call’:
/tmp/r.c:5:3: warning: request for implicit conversion from ‘void *’ to
‘unsigned char *’ not permitted in C++ [-Wc++-compat]
xfer (x, y, arg);
^
I think perhaps the problem is that the warning_at call in
convert_for_assignment that emits this warning should use
expr_loc rather than 'location'. I haven't tested this theory.
