New issue 2151: s390x Instruction Encoding
https://bitbucket.org/pypy/pypy/issues/2151/s390x-instruction-encoding
Richard Plangger:
The first step of this project is to implement the first tests to ensure the
correct instruction encoding.
Test cases comparing generated assembler to objdump (s390
New issue 2152: s390x (2) Bootstrap
https://bitbucket.org/pypy/pypy/issues/2152/s390x-2-bootstrap
Richard Plangger:
As there is no comparable architecture supported, the skeletal structure needs
to be further extended to implement the full 64-bit s390x assembler backend.
The current considered
New issue 2153: s390x (3) Integer arithmetic, Guarding operations, Jumps
https://bitbucket.org/pypy/pypy/issues/2153/s390x-3-integer-arithmetic-guarding
Richard Plangger:
This first step tackles 1/3 of the test_runner test suite. It continues to
extend the skeletal structure and implements many
New issue 2154: s390x (4) Calls, Double precision floating points
https://bitbucket.org/pypy/pypy/issues/2154/s390x-4-calls-double-precision-floating
Richard Plangger:
This task advances to the more challenging aspects of the backend
implementation. It requires to implement calling and most of t
New issue 2155: s390x (5) Advance to 2/3 of the backend tests
https://bitbucket.org/pypy/pypy/issues/2155/s390x-5-advance-to-2-3-of-the-backend
Richard Plangger:
This step further implements the missing opcodes and might remove more the
limitations not conquered earlier. This is an intermediate
New issue 2156: s390x (6) Completing test_runner
https://bitbucket.org/pypy/pypy/issues/2156/s390x-6-completing-test_runner
Richard Plangger:
The task will require nearly all of the test_runner tests to run and correctly
emit s390x machine code. It should include most features but can relax some
New issue 2157: s390x (7) GC
https://bitbucket.org/pypy/pypy/issues/2157/s390x-7-gc
Richard Plangger:
First, the simple BoehmGC will be adapted (if necessary). The actual task is to
implement all necessary routines to fully support incminimark.

New issue 2158: s390x (8) Towards a passing test suite
https://bitbucket.org/pypy/pypy/issues/2158/s390x-8-towards-a-passing-test-suite
Richard Plangger:
Now that nearly all parts have been implemented, all other tests that in the
pypy/ and rpython/ directories should pass. This ensures that the
New issue 2159: s390x (9) Translation
https://bitbucket.org/pypy/pypy/issues/2159/s390x-9-translation
Richard Plangger:
This step ensures that the translation correctly works using the GCC toolchain.
This can be a time consuming task, to get things right. The passing test suite

New issue 2160: s390x (10) Benchmark
https://bitbucket.org/pypy/pypy/issues/2160/s390x-10-benchmark
Richard Plangger:
To evaluate the gain the PyPy JIT compiler is able to achieve, the benchmark
suite will be run using the new s390x backend. This completes the first
implementation of the s390x
