[LLVMdev] question on assembler for systemz backend
...s. For example,

There are different instruction sets for z/System. Basically, you have
to provide proper -march / -mcpu to assembler, otherwise the very old
ISA is assumed.
I don't recall offhand, but you need to provide either z990 or z9-109,
because LLVM assumes that long displacements and ext imm stuff is
available (this is rather fair assumption).

Because it sets lowest (ll) 16 bit word of 64 bits.

[LLVMdev] question on assembler for systemz backend
What assembler are people using with the SystemZ backend?
I am trying to assemble the output of the SystemZ backend with the GNU
binutils assembler (build with --target=s390x-linux). I get errors when
assembling instructions with literals that are negatives. For example,
the test case test/CodeGen/SystemZ/01-RetImm.ll gives errors:
$ s390x-as 01-RetImm.s

I have tried:
s390x-as -m64 -march=z900
s390x-as -m64 -march=z990
s390x-as -m64 -march=z9-109
All give the same error messages. This is with binutils-2....

[RFC/PATCH 00/15] kvm on big iron
This patch series introduces a backend for kvm to run on IBM System z
machines that uses the mainframe's sie virtualization capability. This
work runs 64bit guests on z800/z890/z900/z990/z9/z10 class machines with
a 64bit linux host. Userspace will follow once we're done brushing it
over.
The patch queue consists of the following patches, which can be applied
in sequence on top of kvm.git master as of 2008-03-20 hash g914bd66:

[klibc 00/31] klibc as a historyless patchset (updated and reorganized)
I have updated the klibc patchset based on feedback received. In
particular, the patchset has been reorganized so as not to break
git-bisect.
Additionally, this updates the patch base to 2.6.17-git12
(d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main
difference on the klibc side is removal of obsolete code.
