llvm-mirror/test/Transforms/InstCombine/pow-exp.ll
Jay Foad ed678c9f29 [InstCombine] Remove hasNoInfs check for pow(C,y) -> exp2(log2(C)*y) 
We already check hasNoNaNs and that x is finite and strictly positive.
That only leaves the following special cases (taken from the Linux man
page for pow):

If x is +1, the result is 1.0 (even if y is a NaN).
If the absolute value of x is less than 1, and y is negative infinity, the result is positive infinity.
If the absolute value of x is greater than 1, and y is negative infinity, the result is +0.
If the absolute value of x is less than 1, and y is positive infinity, the result is +0.
If the absolute value of x is greater than 1, and y is positive infinity, the result is positive infinity.

The first case is handled elsewhere, and this transformation preserves
all the others, so there is no need to limit it to hasNoInfs.
