Fedora Update Notification

Name        : alt-ergo
Product     : Fedora 21
Version     : 0.95.2
Release     : 8.fc21
URL         : http://alt-ergo.ocamlpro.com/
Summary     : Automated theorem prover including linear arithmetic
Description :
Alt-Ergo is an automated theorem prover implemented in OCaml. It is
based on CC(X) - a congruence closure algorithm parameterized by an
equational theory X. This algorithm is reminiscent of the Shostak
algorithm. Currently CC(X) is instantiated by the theory of linear
arithmetics. Alt-Ergo also contains a home made SAT-solver and an
instantiation mechanism by which it fully supports quantifiers.

Update Information:

The alt-ergo, frama-c, ocaml-tplib, and why3 builds are simply rebuilds for ocaml-zarith 1.3.  The upstream notes on this version of ocaml-zarith are:
- Fixed inefficiencies in asm fast path for ARM.
- Revised detection of NaNs and infinities in Z.of_float
- Suppress the redundant fast paths written in C if a corresponding fast path exists in asm.
- Use <stdint.h> to ensure compatibility with OCaml 4.02.
- More prudent implementation of Z.of_int, avoids GC problem with OCaml < 4.02 (PR#6501 in the OCaml bug tracker).
- PR#1429: of_string accepts 'a' in base 10.
- Macro change to avoid compiler warnings on unused variables.

This update can be installed with the "yum" update program.  Use
su -c 'yum update alt-ergo' at the command line.
