mips64 crosstool

[Bryan Althouse]

Is anyone using crosstool to produce a 64 bit mips compiler?  

I need to produce a gcc that will accept the -mabi=64 option. I have been
able to generate a 32bit gcc with crosstool, using
TARGET=mips-unknown-linux-gnu.  Must I change this to
TARGET=mips64-unkown-linux-gnu to create a 64bit compiler?  I have tried
this, but crosstool will fail.  It appears as if -mabi=n32 is passed to the
native gcc during the build-glibc-headers step.  This of course causes the
native gcc to give up.

Are there any patches for mips64 tool chain build?  

Thanks to all.

When I was looking at crosstool, it had problems with miltiarch
support for mips. If you want to produce mips64 only tools, you'll
need patches from Maciej which are not there also. And take a look
into build matrix :)

Conclusion - mips is not very well supported in crosstool.

Many thanks to everyone who has helped me on this issue. 

I ended up abandoning the crosstool approach.  It supports mips32 well, but
not mips64.  Linux from scratch has a very good step by step procedure for
building a tool chain for mips64.  I was able to build with very little
headaches.  Unfortunately, I have not yet been able to execute any programs
compiled with the tool chain.  I'm not sure where I went wrong. 

PMC sierra is working on an update for their tool chain.  They have supplied
me with a "beta" version tool chain that has solved my problems.  Now, I am
able to compile with -mabi=64 and -lpthread.  The executable no longer
Segfaults.  Since I'm past this problem, I will probably not spend much more
time trying to build a working tool chain.
