Benjamin Kramer 2746000f4f Add APFloat::getExactInverse. ... The idea is, that if an ieee 754 float is divided by a power of two, we can turn the division into a cheaper multiplication. This function sees if we can get an exact multiplicative inverse for a divisor and returns it if possible. This is the hard part of PR9587. I tested many inputs against llvm-gcc's frotend implementation of this optimization and didn't find any difference. However, floating point is the land of weird edge cases, so any review would be appreciated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128545 91177308-0d34-0410-b5e6-96231b3b80d8		2011-03-30 15:42:27 +00:00
