Hi Jakub, Sorry again for the misunderstanding. Here are revised patches and change logs for trunk, GCC 5, and GCC 4.9. Note that GCC 5 and GCC 4.9 have additional exposures in tree-ssa-math-opts.c that I've repaired similarly. The only differences between 5 and 4.9 are the names of the affected functions.
All have passed regstrap on powerpc64le-unknown-linux-gnu. Are these ok?
