| 13 | Upgrade GMP-ECM to 7.0.3 |
| 14 | |
| 15 | * I haven't repackaged the upstream tarball (`.tar.gz`) [yet]. |
| 16 | Not sure whether we could/should also delete some stuff not |
| 17 | needed for Sage (cf. `SPKG.txt`); at least there's no `spkg-src` |
| 18 | script. |
| 19 | |
| 20 | * I haven't touched `spkg-install` yet. We may address potential |
| 21 | issues with `SAGE_FAT_BINARY` (mentioned both there and in `SPKG.txt`), |
| 22 | as well as known problems with `-march=native -O3` on bdver[1-4] |
| 23 | (AMD FX-???? !Bulldozer/Piledriver, AMD Opteron 6[23]xx, etc.) |
| 24 | where we should add `-mno-xop` because of bugs in (AFAIK) '''every''' |
| 25 | GCC version that supports these processors, silently leading |
| 26 | to broken code ("just" testsuite failures IIRC). |
| 27 | Also, we currently copy Sage's `config.guess` (because it was newer |
| 28 | at some point), which presumably is no longer necessary (but |
| 29 | shouldn't hurt either, provided we keep Sage's up-to-date ''and'' |
| 30 | GMP-ECM won't rely on its own). |
| 31 | |
| 32 | * The doctests in `sage/libs/libecm.pyx` may need some changes, |
| 33 | especially with respect to `verbose` mode tests. (But I'll presumably |
| 34 | work on them elsewhere anyway, independently of this upgrade.) |
