(We don't have the equivalent NSIGTRAP, NSIGBUS, etc for the other si_codes, so maybe deleting is the simplest option. If you want to put a preceding patch that just deletes our TARGET_NSIGFPE definition, you can have my r-by for that.) Otherwise Reviewed-by: Peter Maydell <peter.maydell@linaro.org> thanks -- PMM
