Re: [RFA] mips_push_arguments(): Make O64 ABI test explicit

[Andrew Cagney <ac131313@ges.redhat.com>]

 From mips-tdep.c:

                   /* A non-floating-point argument being passed in a
                      general register.  If a struct or union, and if
                      the remaining length is smaller than the register
                      size, we have to adjust the register value on
                      big endian targets.

                      It does not seem to be necessary to do the
                      same for integral types.

                      Also don't do this adjustment on EABI and O64
                      binaries.

                      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.  */

Sounds like the comment should be updated to mention a few more ABIs and 
confirm that it is GCC that is wrong.   I'll assume this patch is withdrawn.

enjoy,
Andrew
