cagney/2001-07-23: gdb/179: Also, GCC, when
outputting LE O32 with sizeof (struct) <
MIPS_SAVED_REGSIZE, generates a left shift as
part of storing the argument in a register a
register (the left shift isn't generated when
sizeof (struct) >= MIPS_SAVED_REGSIZE). Since it
is quite possible that this is GCC contradicting
the LE/O32 ABI, GDB has not been adjusted to
accommodate this. Either someone needs to
demonstrate that the LE/O32 ABI specifies such a
left shift OR this new ABI gets identified as
such and GDB gets tweaked accordingly. */
