Hi Ying Huang,

Sorry for the delay in reviewing your patch.

I agree that having inconsistent naming schemes for the macros
is annoying.  But I dislike the idea of a backwards incompatible
change.  It is not only the binutils, gdb and glibc that use these
macros but other programs as well.

To that end I have amended your patch so that the changes to
include/elf/mips.h and elfcpp/mips.h also keep the old definitions
of the constants.  This means that other users of these files
will not have to change their code unless they want to.


 >> And we also have submitted this change to glibc.

You will also need to submit the changes to gdb/mips-tdep.c
and sim/mips/interp.c to the gdb mailing list as these files
are not maintained by the Binutils project.

Approved and applied - with the change mentioned above.

One other thing - your email program appears to have mangled
the patch, removing lots of whitespace.  This made the patch
impossible to apply automatically and instead I had to apply
it by hand.  In the future, please could you supply the patch
as an attachment, rather than inline ?

Cheers
   Nick
