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.`
Correct an misunderstanding of MDSRCS. MDSRCS it intended to allow assembly versions of funtions with C implementations listed in MISRCS. The selection of the correct machdep_ldis?.c for a given architecture does not follow this pattern and the file should be added to SRCS directly.

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.

Support armv7 builds for userland Make armv7 as a new MACHINE_ARCH. Copy all the places we do armv6 and add armv7 as basically an alias. clang appears to generate code for armv7 by default. armv7 hard float isn't supported by the the in-tree gcc, so it hasn't been updated to have a new default. Support armv7 as a new valid MACHINE_ARCH (and by extension TARGET_ARCH). Add armv7 to the universe build.

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`
