https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70457 --- Comment #15 from Bill Schmidt --- Matthias, the code is now fixed everywhere upstream. Do you need a merge into ibm/gcc-5-branch?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70457 --- Comment #11 from Bill Schmidt --- Jakub, thanks, I've verified that works and makes for a much better patch. Will post shortly on gcc-patches.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70457 --- Comment #9 from Jakub Jelinek --- I've missed the pass_optimize_widening_mul::execute in your patch, that is also another spot where you'd want to call it. But the sincos hunks should be safe as is.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70457 --- Comment #8 from Bill Schmidt --- The tree-inline part only shows up after fixing the part in tree-ssa-math-opts.c, where the initial failure occurs. The DECL is already encoded as a BUILT_IN_POW by the time we get that far.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70457 --- Comment #7 from Jakub Jelinek --- Ah, but gimple_call_combined_fn already performs this. So perhaps all you need is the tree-inline.c part?

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70457 --- Comment #4 from Bill Schmidt --- (I should say, presumably unreachable. This source code looks pretty dicey in the first place, but nonetheless we should probably tolerate it at this stage of optimization.)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70457 --- Comment #3 from Bill Schmidt --- So we have an unreachable call to pow with the wrong number of arguments. I suppose the expansion logic for builtin_pow should tolerate this situation and just do nothing with it.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=70457 --- Comment #2 from ktkachov at gcc dot gnu.org --- Using gdb, the gimple stmt causing the ICE is: # .MEM_10 = VDEF <.MEM_1(D)> ret_5 = pow (1.0e+0);
