Michael Felt added the comment: I have been doing manual tests - and it seems build is broken for AIX and xlc. I shall be working on a git bisect to try and identify what broke it for xlc-v11. Finding what broke xlc-v13 will require more time. Note: it is no longer limited to _decimal not

Michael Felt added the comment: I switched the "aixtools" bot back to "xlc", and also back to my POWER6 server that runs xlc-v11. iirc it is xlc-v13 (or maybe even v12) that is having trouble with _decimal (or is it POWER8). From memory, _decimal was compiling properly with xlc-v11. Although

Stefan Krah added the comment: Thanks! Ha, it turns out that c99_r has excellent C99 compliance. :) > Variable arguments macro RAISE_SYNTAX_ERROR was invoked with an empty > variable argument list. Totally legit, we should use xlc (at least the front end) more often. So maybe our code

Michael Felt added the comment: I'll switch my bot https://buildbot.python.org/all/#/builders/119 to use c99_r rather than xlc_r. Test 1129 will b e the first with c99_r (and xlc v13). On 11/06/2020 00:37, Stefan Krah wrote: > Stefan Krah added the comment: > > So it would still be

Stefan Krah added the comment: So it would still be interesting to see what happens if you compile libmpdec with c99_r (emphasis mine): """ This command supports all ISO C99 language features, but does not support IBM language extensions. Use this invocation for *strict* conformance to the

Stefan Krah added the comment: Thanks for this information. The buildbot, however, fails to compile C99 extern inline functions. Example: ld: 0711-317 ERROR: Undefined symbol: .mpd_issnan I understand the C99 extern inline feature like in this explanation:

Michael Felt added the comment: Actually, iirc - xlc is c99 plus a few extra settings. The configuration files for xlc are, traditionally, in /etc (the later versions of the compiler have moved them into /opt/show/where so that multiple versions of the compiler can be installed.

[issue40878] Use c99 on the aixtools bot

New submission from Stefan Krah : There appears to be an xlc buildbot with libmpdec failures. libmpdec uses C99 extern inline semantics. From the brief period that I had access to xlc I remember that xlc was quite picky about C99. Actually all of Python uses C99. So I think xlc_r needs to be
