This provides support for targets without Float128 in their libc/libm. It covers: * long double is 128b IEEE754 * _Float128 support is provided in libc * __float128 support is available and uses libquadmath.
It has been tested as follows: x86_64-linux (with libc support, uses libc) x86_64-darwin (without libc support, uses libquadmath) aarch64-linux (with libc support, uses libc) aarch64-darwin (without libc support, uses libquadmath) powerpc64le (glibc-2.17 - without libc support, uses libquadmath) powerpc64le (glibc2.34 - with libc support) --with-long-double-format=ieee uses xxxieee128 --with-long-double-format=ibm uses xxxf128 Thanks to Jakub for the suggestion on handling the long double case. Most of the patch is mechanical - the tricky parts are really in the configuration.
