I've taken Michael's patch, tweaked it to address the concerns
listed above (which includes Daniel's concerns about the corefile
sniffer), and then added a few more tweaks so that it works with
actual am33 core files.
Here is what was committed:
* mn10300-linux-tdep.c: New file.
* Makefile.in (mn10300-linux-tdep.o): New Makefile target.
* config/mn10300/linux.mt (TDEPFILES): Add mn10300-linux-tdep.o and
corelow.o.
* mn10300-tdep.h (E_E8_REGNUM, E_E9_REGNUM, E_E10_REGNUM)
(E_FPCR_REGNUM, E_FS0_REGNUM): New constants.
