Then we should inform them about that at least. I don't think the compiler reports any optimizations not done to the user at lower optimization levels? It's normal not to do certain optimizations at a lower level, that's why we have -O0 -O1 -O2 ... or do you mean something else by that? > I'm thinking about this for some time.

The compiler processes one function at a time, all passes at once. It doesn't mix passes of different functions. So I think using global variable in sh.cc + override 'set_current_function' should get the job done. When the insn split code is executed, just set the global flag in the SH specific function context. > I see some strange new exec fails only at testsuite logs.
