[Bug target/16627] New: "Unrecognized opcode" error while building cross compiler for powerpc

[gkyla at central dot ntua dot gr]

My machine is (uname -a): 
 
Linux kentri 2.6.7-gentoo-r11 #5 Mon Jul 19 07:26:39 EEST 2004 i686 Intel(R) 
Pentium(R) M processor 1500MHz GenuineIntel GNU/Linux 
 
I use (gcc --version): 
gcc (GCC) 3.3.3 20040412 (Gentoo Linux 3.3.3-r6, ssp-3.3.2-2, pie-8.7.6) 
as a native compiler. 
 
configure options for gcc were: 
../gcc-3.4.1/configure --target=powerpc-ibm-aix4.3.2.0 --prefix=/usr/local 
--enable-languages=c 
from within directory /home/cross/gcc-3.4-aix. 
 
I have already installed binutils-2.14.90.0.8 in /usr/local using the same 
"--target" configure option (and nothing else), plus all the 
necessary /usr/include headers from a nearby powerpc machine 
in /usr/local/powerpc-ibm-aix4.3.2.0/include. 
 
Build was initiated with a plain "make" inside /home/cross/gcc-3.4-aix. 
 
The last lines of the build before it fails are: 
 
/home/cross/gcc-3.4-aix/gcc/xgcc -B/home/cross/gcc-3.4-aix/gcc/ 
-B/usr/local/powerpc-ibm-aix4.3.2.0/bin/

Invalid as now binutils 2.15 is required for PPC.

Unfortunately, the problem remains with binutils-2.15. Specifically, I have 
tried with binutils versions 2.15, 2.15.90.0.3 and 2.15.91.0.1 (always using 
the same configure and build commands) and they all show the same error at the 
same place as my initial post. I paste it here as well for completeness:

What happens if you add --with-gnu-as to the configure line?

I get the same results :( 
 
PS. GCC compiled fine for hppa64-hp-hpux11.11 with --with-gnu-as (bug 16642), 
thanks.

/tmp/ccIAkaC2.s:509: Error: Unrecognized opcode: `mfcr'   hmm, this looks like a configure problem 
somewhere because mfcr is a standard powerpc instructions.

I might have found the problem configure is finding the wrong as.
I think you should read <http://gcc.gnu.org/ml/gcc/2004-05/msg01389.html>.

By the way this works for me.
