Use the correct values for softfloat, in both the little endian and the big endian cases. 2005-03-20 00:53:52 +00:00			`# Long double is just double precision.`

Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP} if not already defined. This allows building libc from outside of lib/libc using a reach-over makefile. A typical use-case is to build a standard ILP32 version and a COMPAT32 version in a single iteration by building the COMPAT32 version using a reach-over makefile.

Make armv6 hard float abi by default. Kill armv6hf. Allow CPUTYPE=soft to build the current soft-float abi libraries. Add UPDATING entry to announce this. Approved by: re@ (gjb) 2016-05-18 06:01:18 +00:00			`.if ${MACHINE_ARCH:Marmv6} && (!defined(CPUTYPE) \|\| ${CPUTYPE:Msoft*} == "")`
Add the fp{get,set}{mask,round} functions to the public symbols in the map. These are only exported for armv6hf as the soft-float ABIs have these in the softfloat Symbol.map file. 2014-09-05 18:11:36 +00:00			`SYM_MAPS+=${LIBC_SRCTOP}/arm/Symbol_vfp.map`
