Unless you configured GCC with a 2.32 or new glibc (such as in Advance Toolchain 14), when you change the default long double representation, the compiler gives a warning that you can't depend on GLIBC to have all of the necessary support for __float128. Using -Wno-psabi supresses this warning. For assembly tests, we don't care if GLIBC supports it or not, but we don't want the warning. Note, there is still a hole with Fortran, in that it doesn't support multiple long double types like C/C++ do, so you can't really change the long double behavior and expect your program to work. -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460-6245, USA email: meiss...@linux.ibm.com, phone: +1 (978) 899-4797
