--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- The Procedure Call Standard for the ARM Architecture does not include a 128-bit floating-point type, so if you want to support such a type in GCC for ARM you should first work with arm.e...@arm.com to define the associated ABI and get a new version of AAPCS released. Or you could use AArch64 - AAPCS64 does include such a type.
