* Add portable bit mask operations to BitVector.Jakob Stoklund Olesen2012-01-171-0/+63
| | | | | | | | | | | | BitVector uses the native word size for its internal representation. That doesn't work well for literal bit masks in source code. This patch adds BitVector operations to efficiently apply literal bit masks specified as arrays of uint32_t. Since each array entry always holds exactly 32 bits, these portable bit masks can be source code literals, probably produced by TableGen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@148272 91177308-0d34-0410-b5e6-96231b3b80d8
