Re: Calling a MIPS maintainer (was Re: GCC build failed for mips-elf with your patch on 2002-06-18T19:37:45Z.)
Since I'm in the midst of trying to make the CPU config files a bit cleaner,
I thought I'd provide some feedback:

I can't find the new patch. All I can find is followup discussion.
It looks the the problem now is that you're duplicating the generic
routines inside the mips atomicity.h, and then switching between them.
That won't work, because if/when we change the generic versions, mips will
get left out in the cold.
The MIPS I vs MIPS II switch must be done /outside/ atomicity.h.
