[llvm-commits] [PATCH][FastMath, InstCombine] Fadd/Fsub optimizations

[Shuxin Yang]

Hi, Eli:

    It is committed in r170471. All the problems you figured out are fixed:
   - the lame sorting are completely deleted.
   - drillDownOneStep() is renamed for overloaded functions.

   ...

   In addition to that, I correct some typos as well as some cosmetical 
changes
in order to conform to the coding std (mostly are about "Ty &A" vs "Ty& A".

  Thank you so much for your time! I really appreciate it.
