| | | | | | | | | | | | | two's complement bignum arithmetic. They could be used to implement much of APInt, but the idea is they are enough to implement APFloat as well, which the current APInt interface is not suited for.

| | | | | | | | | | | 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
