>Organization:
>Environment:
The hostsystem is based on Redhat 7.1
The crosscompiler which caused the error was compiled with
the following options in the RPM-specfile:
  ./configure \
              --host=$my_arch \
              --target=powerpc-linux \
              --prefix=%{ROOT}/$my_arch/local \
              --enable-shared \
              --enable-languages="c,c++,f77" \
              --with-headers=%{ROOT}/%{TARGET}/include \
              --with-libs=%{ROOT}/%{TARGET}/lib \
              --with-cpu=403 --without-fp

and should produce code for a PowerPC 405GP.
We applied 2 Patches:
gcc-2.95.2-franz.patch
gcc-powerpc-fpu.patch

The compiler works fine and compiles the linuxkernel and
the libraries without any problems.
>Description:
I tried to get gcov and gprof running on my crosscompiling
environment. Unfortunatly I got some errors compiling my 
testprogram for the target. The host gcc works fine and 
causes no problems with the same options and sources.

1. gprof
=======
My powerpc-linux-gprof tool seems to work, only my compiler is a bit
strange. Trying the -a option to enable basic block counting I got:
 
powerpc-linux-gcc -Wall -g -c -o test.o test.c -a -pg
cc1: warning: `-a' option (basic block profile) not supported
 
but I got at least a working test program and could manage to run
it on the walnut. The comparision of the gprof output on the host and
on the walnut was ok.
 
2. gcov
=======
Trying to compile test.c with support for coverage testing I got the
following errors:
 
powerpc-linux-gcc -Wall -g -O2 -fprofile-arcs -ftest-coverage -c -o test.o test.c
powerpc-linux-gcc: Internal compiler error: program cc1 got fatal signal 11

The complete output was:
/opt/fsp/i586-pc-linux-gnu/local/bin/powerpc-linux-gcc -v -save-temps -Wall -g -O2 -fprofile-arcs -ftest-coverage -c -o test.o test.c

If you cannot make it work it would be a great help for
