porting EGCS to the Cray T3E

["Julian C. Cummings" <julianc at acl dot lanl dot gov>]

Hi,

I am interested in trying to port the EGCS compiler to the Cray T3E.  I am
using a June 13th snapshot of the EGCS sources.  I unpacked the sources and
created a directory egcs-objdir for building the compiler.  The first thing I
discovered when I tried to run the configure script was that it is not familiar
with the Cray T3E architecture.  So I edited the config.sub file and added a
case for the host type "crayt3e" which sets basic_machine to "crayt3e-cray" and
sets os to
"-unicosmk".  (This is based on what you get when you run "uname -m" and "uname
-v" on the T3E.)  Then I ran configure like this:

configure --prefix=/usr/tmp/julianc/EGCS/egcs-objdir --host=crayt3e

It told me it was creating a Makefile, then it whirred for a while, and finally
it came back and reported a failure in configuring egcs-objdir/gcc.  Below is
the config.log output from egcs-objdir/gcc.  I don't see offhand why the
configuration failed.  If anyone can help me with interpreting the configure
output and understanding this problem, I would very much appreciate it.  Is the
EGCS compiler supposed to be directly portable to Cray platforms in this way?

Thanks, Julian C.
