--- Comment #181 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> --- Just as a heads-up: I am currently performing extensive testing to be able to generate anything useful from testsuite results to a usable backtrace. For that, I am building GCC natively with various options on sh4. Will report back as soon as I have something.
