189a300b11 feat(frontends/lean): improve pretty printing space insertion heuristic 2015-09-30 17:36:32 -07:00

8fd8ff2773 fix(frontends/lean): ignore reserved notation for pretty printing 
Because reserved notation uses `Prop` as a dummy expression, pretty
printing `Prop` unnecessarily invokes pp_notation on every reserved
notation entry.

cb2f93ee6a fix(kernel/expr,kernel/level): performance problem 
The method unordered_set::clear takes time O(n) where n is the number of
buckets in the hashtable used to implement the set.
Moreover, it does not reduce the number of buckets to 0.
That is, it keeps `n` empty buckets.

This creates performance problems if the number of buckets gets really
huge at one point.
The tst6 at tests/kernel/expr.cpp demonstrates the problem

c652eeeac6 feat(library/data/expr): add support for regular local constants in blast tactic 
We need them when inferring types and checking whether two expressions
are definitionally equal or not.

Remark: they are temporary objects, and should never be included in the
blast state object.

f73051c674 fix(CMakeLists.txt): do not generate DLL when using cross-compilation 
It is not clear why it doesn't work.
This is not a big because we do not use cross-compilation anymore to
generate the official Lean for Windows. We use MSys2 instead.
