Two files seem to be missing for the 386 port. They're called crt1.o and crtn.o. I have made it through the installation directions to step 8 (recompile the compiler with itself) at which point make complains that it can't find the two files. Also, is this port going to work on a Sun386i? I've been using i386v, but this isn't System V.

This is a SysV-ism (needed to support shared libraries). Have it use crt0.o instead. -- James R.

Has anyone ported GCC (and G++) to the PS/2 MOD 70 or 80 running AIX ? Any pointers appreciated ! John Cohn Carnegie Mellon University

Here are the config files needed to compile gcc under ibm ps2 aix.
It is not perfect and it still has the following bugs:
o the -g does not generate the correct assembly code for the assembler
to generate the correct dbx debugging info. Somehow the ps2 aix
assembler does not understand the .stab commands. Somebody that knows
how the ibm dbx work could fix that one.
o the ibm ps2 assembler has a bug in its span optimization code. The
current setting disable completely the span optimization feature of the
assembler.
You will have to modify the config.gcc to include the follwing lines:
aix386 | ps2aix ) # for IBM PS/2 running AIX
machine=aix386
cpu_type=i386
configuration_file=xm-${machine}.h
target_machine=tm-${machine}.h
;;
The following "tm-aix386.h" and "xm-aix386.h" are modification of the
gcc "tm-i386v.h" and "xm-i386v.h".
