I think I just discovered a bit more info concerning the optimizations
mentioned by YAMAMOTO Mitsuharu.
Somewhere in this part of xfaces.c:
6696 CHECK_LIVE_FRAME (frame);
6697 f = XFRAME (frame);
6698
6699 for (i = 0; i < LFACE_VECTOR_SIZE; i++)
6700 attrs[i] = Qunspecified;
6701 merge_face_ref (f, attributes, attrs, 1, 0);
According to the gdb output below (I had to re-compile with -gstabs+
for 'f' to even print on my machine),
when we get to the breakpoint at 6696, 'f' seems -- to my uneducated
eye -- to already contain a value valid enough that gdb goes ahead and
prints it. But I'm pretty sure its garbage.
When I issue 'step' to gdb, it doesn't stop at 6697, but at 6699
instead, and 'f' still seems to contain the exact same address.
But when I set a breakpoint at 6701 -- the first statement after the
loop -- and continue to it, 'f' now contains 0x12.
Then, if I step into merge_face_ref and 'p f', it has a 3rd distinct
value.
After returning from merge_face_ref, 'p f' displays a *4th* value.
Especially interesting to me is that the 3rd value is the only that
looks like it is actually valid, since the struct members
'output_method', 'desired_cursor' and 'blink_off_cursor' have been
filled in with names by gdb.
