System: Linux alps 2.4.19 #3 Mon Nov 25 10:57:02 MET 2002 alpha unknown
Architecture: alpha
host: alphaev5-bruli-linux-gnu
build: alphaev5-bruli-linux-gnu
target: alphaev5-bruli-linux-gnu
configured with: ./configure --prefix=/usr --exec-prefix=/usr --host=alphaev5-bruli-linux --enable-threads=posix --enable-shared --disable-static
>Description:
Compiling glibc-2.3.1 using -mcpu=ev5 generates code that does
not run correctly on alpha/ev5.
Compiling ssh-3.1 using -mcpu=ev5 generates code that does not
run at all.
>How-To-Repeat:
Compile the source using -mcpu=ev5 on a ev5 machine and try
to run this code.
>Fix:
Using -mcpu=ev4 generates runnable code. (The advantages of
the ev5 over the ev4 is lost).

Which versions did you try?
All.
- 3.0.1
- 3.0.2
- 3.0.3
- 3.0.4
- 3.1
- 3.1.1
- 3.2
- 3.2.1
This took me about one year! Because after compile and install
of the compile I rebuilt or at least I tried to rebuild all of
1. binutils
2. gcc again, with the new binutils from step 1
3. linux kernel
4. modutils
5. glibc-2.2.5
After the rebuild of all this I run the new installation and
tested out some applications including
- apache
- mysql
- squid
- ssh
- wu-ftpd
- openssl
- ISC bind
- gdb
The test consisted of compile/build, install and run some test
scripts comparing the results to the correct results generated
on a gcc-2.95.3 based installation.
When ever I found fatal errors I went to the next gcc version
starting at the beginning of the build process but it got worse
from version to version.
At the end I gave up and reinstalled the system totally based on
gcc-2.95.3. - That's the story.

Then this will be very tricky to sort out the problem.

Hi,
No I can't.
The last gcc version you can compile and run all off
- linux-2.4
- glibc-2.2.5
- modutils-2.4
is 2.95.3. All later version will generate invalid (not runnable
code) on my alphas. And I have tested _all_ versions after 2.95.3.
No I went back to 2.95.3 with the disadvantage that the most
recent glibc version that can be compiled is 2.2.5.
Regards,
Martin

Could you be more specific? Does it crash? With what signal?
