Right now I'm thinking that I have callee-super in there as a
hold-over from back when I first was starting and built everything as
ARM. Now that I'm building things as THUMB it doesn't look like
callee-super is necessary.
Now, with 4.4 and 4.5, I'm having the following build problem:
tests.c: In function ‘print_packet’:
tests.c:65:1: error: insn does not satisfy its constraints:
(insn 215 23 24 3 tests.c:52 (set (reg/f:SI 6 r6 [171])
(reg/f:SI 13 sp)) 168 {*thumb1_movsi_insn_osize} (nil))
tests.c:65:1: internal compiler error: in
reload_cse_simplify_operands, at postreload.c:396
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.5/README.Bugs> for instructions.
However, removing the offending code still does not make a simple
blink program work. I don't have either of these problems with
gcc-4.3-arm-linux-gnueabi from emdebian.org... I imagine it's going to
take some deeper work with the debugger to figure out what's going on
with 4.4 and 4.5.
