Benjamin Kramer a6ff92a975 InstCombine: Don't just copy known bits from the first operand of an srem. 
That's obviously wrong. Conservatively restrict it to the sign bit, which
matches the original intention of this analysis. Fixes PR15940.

InstCombine.h Added a function scalarizePHI() that sclarizes a vector phi instruction if it has only 2 uses: one to promote the vector phi in a loop and the other use is an extract operation of one element at a constant location. 2013-04-18 19:35:39 +00:00
