Dan,


For such a radical change to fly, I think this should be a runtime 
replacement for the existing dwarf2 reader.

That way people can test the two side by side.  It will give people 
greater confidence and an easy reference point.

Some trivia:

> #ifndef DWARF2_REG_TO_REGNUM
> #define DWARF2_REG_TO_REGNUM(REG) (REG)
> #endif



this shouldn't be needed.  If it is then there is a bug in multi-arch.

> #if defined(HAVE_MMAP) && defined(HAVE_GETPAGESIZE)
> #include <sys/mman.h>
> #endif


It should be posible to structure things so those #if #else #endif's are 
largely eliminated.  You want as much of your code to be exposed to the 
C (not C++ :-) compiler at all times.  That mysterious #if D2FIX is 
similar.  Does bfd already provide an MMAP facility?

You'll eventually want to go over the code with a fine tooth comb - 
flush out the naughtness in the old dwarf2reader and eliminate the 
neuances you, your self have introduced.

	Andrew
