Subject: [gcc r13-681] libgcc: Enable XF mode conversions to/from DFP modes only if supported
Date: Fri, 20 May 2022 07:33:28 +0000 (GMT)	[thread overview]
Message-ID: <20220520073328.6BB573857820@sourceware.org> (raw)

commit r13-681-g43ccb7e445329dd9557b42e7289a87a8071ab0f7
Author: Christophe Lyon <christophe.lyon@arm.com>
Date:   Wed Mar 23 15:26:14 2022 +0000

    libgcc: Enable XF mode conversions to/from DFP modes only if supported
    
    Some targets do not support XF mode (eg AArch64), so don't build the
    corresponding to/from DFP modes convertion routines if
    __LIBGCC_HAS_XF_MODE__ is not defined.
