Arie Gurfinkel 972ab6298c (mev) only reduce function interpretation 2017-06-21 22:59:52 -04:00
Arie Gurfinkel 493a3a6312 (mev) call expand_value only at the end 
There is no need to expand array values throughout evaluation.
They are expanded during array equality checking (if requested), and
can be expanded at the very end of evaluation (if needed).

Arie Gurfinkel d5ca902bf6 (mev) bug fix in expanding array equalities 
The stores were processed in the wrong order so that

  (store (store a x y) x u)

was reduced to

  (store a x y)

instead of

  (store a x u)

Dan Liew 4b517b96df [CMake] Move CMake files into their intended location so the 
`contrib/cmake/bootstrap.py` script no longer needs to be executed.

The previous location of the CMake files was a compromise proposed
by @agurfinkel in #461. While this has served us well (allowing progress
to be made) over time limitations of this approach have appeared.

The main problem is that doing many git operations (e.g. pull, rebase)
means the CMake files don't get updated unless the user remembers to
run the script. This can lead to broken and confusing build system
behaviour.

This commit only does the file moving and necessary changes to
`.gitignore`. Other changes will be done in subsequent commits.
