* Upgrade Flocq to version 2.6.1 from upstream (#71)Xavier Leroy2018-04-252-2/+269
| | | | | | | | | | | | | | | | We were previously at 2.5.2. Quoting the NEWS from upstream: Version 2.6.1: - ensured compatibility from Coq 8.4 to 8.8 Version 2.6.0: - ensured compatibility from Coq 8.4 to 8.7 - removed some hypotheses on some lemmas of Fcore_ulp - added lemmas to Fprop_plus_error - improved examples Also: in preparation for Coq 8.8, silence warning "compatibility-notation" when building Flocq, because this warning is on by default in 8.8, and Flocq triggers it a lot.
* Adapt proofs to future handling of literal constants in Coq.Guillaume Melquiond2017-03-084-15/+15
| | | | | | This commit is mainly a squash of the relevant compatibility commits from Flocq's master. Most of the changes are meant to make the proofs oblivious to the way constants such as 0, 1, 2, and -1 are represented.
