Hello Group,
I need some help with Deja Gnu for testing a ported version of gcc for a custom processor. I have downloaded Deja and untarred it into a directory.
I then ran
./configure make make install
as specified in the INSTALL file. So, now Im sure it got installed well. But how do I run it to verify the custom version of gcc.
My gcc (the one I use for Linux running on AMD Athelon XP 2400) is as below:
bash-2.05b$ gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared --enable-threads=posix --disable-checking --host=i386-redhat-linux --with-system-zlib --enable-__cxa_atexit
Thread model: posix
gcc version 3.2 20020903 (Red Hat Linux 8.0 3.2-7)
bash-2.05b$
When I want to shift to the new ported gcc (whose output I currently use with a simulator in GDB), I use this shell script:
bash-2.05b$ cat setup
echo "=============================================="
echo "Setting Environment for GCC compiler for RPINE"
echo "=============================================="
export GCC_EXEC_PREFIX=/opt/GNUPlus/rpine/lib/gcc-lib/
export PATH=${GCC_EXEC_PREFIX}/rpine-elf32/3.3:$PATH
export PATH=/opt/GNUPlus/rpine/rpine-elf32/bin:$PATH
export PATH=/opt/GNUPlus/rpine/bin/:$PATH
export LD_LIBRARY_PATH=/opt/GNUPlus/rpine/lib/gdb:${LD_LIBRARY_PATH}bash-2.05b$source ./setup
That last one was the command I am to give to use the ported gcc instead of the regular one. The version of this ported gcc is:
bash-2.05b$ source ./setup
==============================================
Setting Environment for GCC compiler for RPINE
==============================================
bash-2.05b$ gcc -v
Reading specs from /opt/GNUPlus/rpine/lib/gcc-lib/rpine-elf32/3.3/specs

Thread model: single
gcc version 3.3 20040831 (rpine_support_release-1.0)
bash-2.05b$
Now, I guess, you have a picture of what is going on. I have two versions of Gcc installed in my system and depending on which target I am compiling for, I change the path so that, that gcc version is used. When I configure and make deja, the path is ofcourse for the AMD-Linux-targetted gcc. But I want to test our "rpine" gcc with this installation of deja (I hope I am not confusing you). How do I do this?
From my side, I went through Deja site and read all that was written (at some point it was even suggested that I create a separate user for the purpose) and all that confused me like hell. Can someone explain the following in simpler terms.
1. How to run the test suite on a cross-compiler that co-exists with a native installation? (Refer above to the setup).
2. How to add/delete tests to this suite? (Also, I couldnt see any test-case programs with it)
3. How do I obtain/store results?
I've done much searching, but all that left me more confused.
Kind regards, Harsha.
