New Blackfin configurations
Mon Mar 5 15:01:00 GMT 2007
The current bfin-uclinux target tries to support two kinds of binaries:
flat, which is a really simple format used on nommu systems, and FD-PIC
ELF, which is quite similar to normal Linux ELF binaries but works on
nommu as well.
It's not possible to support both of these well with a single toolchain
- e.g. you can't really configure libstdc++ or libgcc to build a shared
library for only one multilib. Hence we split the toolchain into
bfin-uclinux (for flat binaries) and bfin-linux-uclibc (for FD-PIC).
This patch, which I've committed as 122552, implements these changes
which we've had in our local tree for a while now. I've had some
trouble with the new toplevel libgcc where parts of the configuration
seem to be coming from two different toplevel directories (which is
mildly insane); I'll need to look at this further but at the moment it's
Also bootstrapped on i686-linux for the config/linux.h change.
