Some data from the lnt test suite:
Compile time: I did not see any changes which are not noise.
Execution time: There are a few benchmarks with improvements, but I think most (if not all) is noise.
Static statistics data:
This optimization effects redundant stores of the form:
%x = load %p
store %x, %p
With this patch the compiler can eliminate 131 more redundant stores of this kind.
