MIPS questions

[jtm at smoothsmoothie.com (Jay Monkman)]

I'm working on a MIPS BSP, and have a couple questions.

Does anybody have TCP/IP working? Unless I make changes, I get
alignment errors. During processing, the stack overlays the TCP source
and dest port numbers with the address of the mbuf. Since there's no
guarantee those stay aligned, how is TCP working on MIPS? It looks
like the fixes we put in for ARM will fix this also.


In _CPU_ISR_Set_level in cpukit/score/cpu/mips/cpu.c, there's a chunk
of code:
  sr = srbits | ((new_level==0)? (0xfc00 | SR_EXL | SR_IE): \
                 (((new_level<<9) & 0xfc00) | \
                  (new_level & 1)?(SR_EXL | SR_IE):0));

I think there needs to be parentheses around the last line. Without
the parentheses, the statement turns into:
  sr = srbits | ((new_level==0)? (0xfc00 | SR_EXL | SR_IE): \
                 (SR_EXL | SR_IE));

Or am I missing something?

Thanks.
