Great, thank you. I couldn't reply earlier as I was just on my way.

I've just attempted "configure" on s390 and here is what I get:
configure:35266: checking whether the C compiler works
configure:35288: /usr/bin/gcc -m32-m32   conftest.c  >&5
gcc: error: unrecognized command line option '-m32'
gcc: error: unrecognized command line option '-m32'
configure:35292: $? = 1
configure:35330: result: no
configure: failed program was:
| /* confdefs.h */
| #define PACKAGE_NAME "OpenJDK"
| #define PACKAGE_TARNAME "openjdk"
| #define PACKAGE_VERSION "jdk9"
| #define PACKAGE_STRING "OpenJDK jdk9"
| #define PACKAGE_BUGREPORT "build-dev@openjdk.java.net"
| #define PACKAGE_URL "http://openjdk.java.net;
| /* end confdefs.h.  */
| 
| int
| main ()
| {
| 
|   ;
|   return 0;
| }
configure:35335: error: in `/jdk-hs':
configure:35337: error: C compiler cannot create executables

Indeed:
 sh-4.2# gcc -m32 conftest.c 
gcc: error: unrecognized command line option ‘-m32’
 sh-4.2# echo $?
1
 sh-4.2# gcc conftest.c
 sh-4.2# echo $?
0 

This must have broken recently :( I'll take a look. As it's preventing
me to test JDK-8201495

Is there a bug for this already?

Thanks,
Severin

I agree. It's not ideal, and should be fixed. It's on my todo list but keep 
sinking to the bottom. If you want, you can open a bug on it and I just might 
get around to it a bit quicker. :)

Short note, internally at SAP we have a proprietary port for HPUX
parisc and yes, upward growing stack is quite a problem. We had to
make (and continue to maintain) a lot of downstream changes which deal
with that. So I doubt that even if you manage to build the VM would be
running for long.

Best regards, Thomas

Invalid use of -m32 on certain targets

[John Paul Adrian Glaubitz]

Hi!

I have been playing around with Zero on new (old) architectures and one
of them is hppa, which needs some additional work due to its stack growing
from bottom to top but that's another story.

Anyway, adding hppa to platform.m4 and running configure results in the
following error message:

configure:35290: checking whether the C compiler works
configure:35312: /usr/bin/hppa-linux-gnu-gcc -m32-m32   conftest.c  >&5
hppa-linux-gnu-gcc: error: unrecognized command line option '-m32'
hppa-linux-gnu-gcc: error: unrecognized command line option '-m32'
configure:35316: $? = 1
configure:35354: result: no
configure: failed program was:

Didn't we recently have the discussion about which target gcc versions
understand "-m32" and which don't? Apparently, someone thought hppa's
gcc supports that option but apparently it doesn't.

Was there any conclusion on this discussion? I remember that some
people mentioned that the current situation is not ideal.

Adrian
