I am trying to compile GCC 4.4.6 using  xlc 11.1.0.0 on AIX 6.1 TL-05 SP-2.

Hi Richard:

Thank you for your response.

I looked at the documentation for xlc and by default the optimizations are
turned off

http://publib.boulder.ibm.com/infocenter/comphelp/v111v131/index.jsp?topic=/com.ibm.xlc111.aix.doc/compiler_ref/opt_strict.html
 

Defaults
-qnooptimize or -O0 or -qoptimize=0 

Please let me  know if you  have more suggestion to resolve this issue.

I tried with -O0 and also tried with a different version of the compiler - I
was using Vac 11.1.0.0   when I originally reported the problem. I changed to
9.0.0.16 and even with that compiler the  bootstrap fails at the  same place
with the same message.

Can you please  suggest the next step in debugging this issue?

Thank you.

Hi Richard:

I came across this URL that seems to address the issue I am dealing with:

http://code.redbrain.co.uk/cgit.cgi/gcc-dev/tree/gcc/ChangeLog?h=documentation&id=168023c94f697cb34b098b3715917dae53eb48f1
 

Have you seen this and if not I would request you to take a look at it and
advise accordingly.

Hi Richard

Here is the answer to the problem I reported:

http://gcc.gnu.org/install/specific.html#x-ibm-aix 

I will need fixes for AIX 6.1 APAR IZ98732  since I am at TL05

I have a PMR open with Austin and working with  them to get an I-FIX so that I
could beta test  the APAR.

Will let you know how it goes.

I am trying to compile GCC 4.0.2 using  xlc 11.1.0.0 on AIX 6.1 TL-05 SP-2.

config.guess shipped with 4.0.2 was distribution was returning incorrect value

$ ./config.guess

I replaced it with the version of config.guess shipped with automake-1.11 . 
the new script would return the correct value

$ ./config.guess

Hi Andrew and Richard:

Thank you for the response. I will trying  building GCC 4.4.6  under the same
environment and see if  things go smooth.
