* Fix infinite recursion in ScaledNumber::toInt.Diego Novillo2015-05-011-0/+5
| | | | | | | | | Patch from dexonsmith. The call to toInt() was calling compareTo() which in some cases would call back to toInt(), creating an infinite loop. Fixed by simplifying the logic in compareTo() to avoid the co-recursion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236326 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix private constructor for ScaledNumber.Diego Novillo2015-04-301-0/+24
| | | | | | | | | | | | | | | | | | | | | | | Summary: The private constructor for ScaledNumber was using uint64_t instead of DigitsT. This was preventing instantiations of ScaledNumber with anything other than uint64_t types. In implementing the tests, I ran into another issue. Operators >>= and <<= did not have variants for accepting other ScaledNumber as the shift argument. This is expected by the SCALED_NUMBER_BOP. It makes no sense to allow shifting a ScaledNumber by another ScaledNumber, so the patch includes two new templates for shifting ScaledNumbers.

* [cleanup] Re-sort all the #include lines in LLVM usingChandler Carruth2015-01-141-1/+0
| | | | | | | | | | | utils/sort_includes.py. I clearly haven't done this in a while, so more changed than usual. This even uncovered a missing include from the InstrProf library that I've added. No functionality changed here, just mechanical cleanup of the include order. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@225974 91177308-0d34-0410-b5e6-96231b3b80d8

Start extracting helper functions out of -block-freq's `UnsignedFloat` into `Support/ScaledNumber.h` with the eventual goal of moving and renaming the class to `ScaledNumber`. The bike shed about names is still being painted, but I'm going with this for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211333 91177308-0d34-0410-b5e6-96231b3b80d8
