[parisc-linux] binutils 32/64 bit question

[Mike Frysinger]

has anyone toyed around with having the default hppa binutils support both 
32bit and 64bit code ?

i was thinking along the lines of how sparc binutils sets the default target 
based upon the configure target (32bit or 64bit), but always includes support 
for the other ...

The main problem is that ld is different.  It would take some work
to merge them.  The 64-bit ld uses .opd's and the 32-bit ld doesn't.
There are advantages to using .opd's (e.g., function descriptors
are unique).  We've talked about this but no significant progress
has been made.

Progress on:

a. Adding OPD's to the 32-bit code?

b. Add multiarch binutils support for both 32/64 bit? 

:)

c.
