Hello,

The rs6000 and cr16 backends and unwinding code have a define for the
DWARF frame register for pre-GCC3 compatibility
(PRE_GCC3_DWARF_FRAME_REGISTERS):

gcc/doc/tm.texi.in:@defmac PRE_GCC3_DWARF_FRAME_REGISTERS
gcc/doc/tm.texi:@defmac PRE_GCC3_DWARF_FRAME_REGISTERS
gcc/config/rs6000/rs6000.h:#define PRE_GCC3_DWARF_FRAME_REGISTERS 77

Is this compatibility still needed for rs6000, or can all the
PRE_GCC3_DWARF_FRAME_REGISTERS stuff be cleaned up?


I do not see any reason that compatibility with pre-GCC3 still should
be necessary.  The code was added by RTH and Aldy in 2001, so I want
to make sure they are not aware of any remaining dependency.

Thanks, David

I'm not aware of any.
