Re: SH5 compact register numbering in gcc -> gdb interface - include/elf/sh.h ?


To give gcc and gdb a common interface, it is best put into a header file that
but
gdb/sh-tdep and gcc/config/sh/sh.h (can) include.

I thought of putting it into include/elg/sh.h, since elf is now the predominant
object format for SH gcc.  Or should we start something like an include/dwarf
directory?
But then, it's not strictly dwarf either, since these register numbers are
also used for stabs debugging info (in the SH1..SH4 coff toolchain, or if
you ask specifically for stabs.)
