toolchain update

I'm working on an update to the toolchain.

I've looked at the codesourcery toolchain but their buildscripts
require proprietary tools to run which is of course a pain.
But I've found out that they commit their stuff upstream
so we can use their ARM enhancements anyway :)

The new toolchain will be based on binutils 2.17.50, a snapshot
containing quite a few updates for ARM by the codesourcery people,
and gcc 4.2, which contains support for EABI (not used yet but
will allow a kernel upgrade).

I hope this update will fix both the C++ and AMD64 issues.

I can compile the toolchain and all of dslinux, the kernel boots,
but programs crash immediately producing a long trace which
ends with "frame pointer underrun".

I don't want to commit the new toolchain yet because of this
but I've put up binaries at
and the current patch to produce the new toolchain at

Does anyone have an idea what could be the problem with userland
crashing? I've not yet had time to investigate this problem deeply.

The first thing I want to try next is to disable -mswp-byte-writes
in case I messed up porting the 8bit write problem workaround
to gcc-4.2 properly...

night all,
