I have bootstrapped and regression tested the patch on ia64-unknown-linux-gnu (gcc60) without problems. Also, I have checked that exceptions are generated correctly with various __float128 testcases involving feenableexcept. If there are no further objections, I plan to commit the patch to 4.8 tomorrow. Uros.
