---Problem Description---
greenlet 0.4.14 will not build on ppc64le
Opened https://github.com/python-greenlet/greenlet/issues/136 because attempting to build bdist_wheel for greenlet 0.4.14 on ppc64le Ubuntu 16.04 LTS yields the following error:
running build
running build_ext

In file included from slp_platformselect.h:16:0,

But the greenlet community is saying this is a gcc bug and it would not be safe to revert the greenlet change that exposed this issue. I have no idea whether that is true or not. Supposedly this should be fixed by https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=9213244550335bcb2b8590a0d7d58ac74c932361 but that fix is not present in the latest version of gcc (5.4.0) available for Ubuntu 16.04 LTS.

Machine Type = unavailable due to lab outage
---Debugger---
A debugger is not configured
---Steps to Reproduce---
This should be reproducible with `git clone git://github.com/python-greenlet/greenlet; cd greenlet; python setup.py bdist_wheel`, though it was originally found using pypi rather than github and with a more complicated (scripted) command as detailed in the greenlet bug description.
Contact Information = Matthew Edmonds / edmondsw@us.ibm.com
Userspace tool common name: greenlet
The userspace tool has the following bit modes: no idea
Userspace rpm: N/A
Userspace tool obtained from project website: 0.4.14
*Additional Instructions for Matthew Edmonds / edmondsw@us.ibm.com:
-Attach ltrace and strace of userspace application. |
[Impact]
* GCC has a minor bug w.r.t. clobber r30 register in PIC binaries.
* A patch to fix this has been upstream in 6+
* But it is not in gcc-5.4 as used on xenial
* This prevents compiling future-proof and correct greenlet code, on Ubuntu 16.04 LTS as used by current and supported Openstack Queens release on ppc64el
* Whilst backported greenlet is available via the cloud archive for binary usage, the toolchain is still technically incorrect, and thus hinders using Ubuntu 16.04 LTS as workers in upstream Openstack CI
* As a wishlist it would be nice to backport this one small gcc patch as an SRU
[Test Case]
* git clone https://github.com/python-greenlet/greenlet
* cd greenlet
* ./setup.py build
Expect success
