2009-11-10Fix DenseMap iterator constness.Jeffrey Yasskin
This patch forbids implicit conversion of DenseMap::const_iterator to DenseMap::iterator which was possible because DenseMapIterator inherited (publicly) from DenseMapConstIterator. Conversion the other way around is now allowed as one may expect. The template DenseMapConstIterator is removed and the template parameter IsConst which specifies whether the iterator is constant is added to DenseMapIterator. Actually IsConst parameter is not necessary since the constness can be determined from KeyT but this is not relevant to the fix and can be addressed later.

2007-11-01Added typedef "value_type" to DenseMap (similar typedef appears in std::map).Ted Kremenek
Added method FindAndConstruct() to DenseMap, which does the same thing as operator[], except that it refers value_type& (a reference to both the key and mapped data pair). This method is useful for clients that wish to access the stored key value, as opposed to the key used to do the actual lookup (these need not always be the same). Redefined operator[] to use FindAndConstruct() (same logic). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@43594 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-05When clearing a SmallPtrSet, if the set had a huge capacity, but theChris Lattner
contents of the set were small, deallocate and shrink the set. This avoids having us to memset as much data, significantly speeding up some pathological cases. For example, this speeds up the verifier from 0.3899s to 0.0763 (5.1x) on the testcase from PR1432 in a release build. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40837 91177308-0d34-0410-b5e6-96231b3b80d8
