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.

libc: Simplify soft-float on 32-bit arm Simplify the tests for 32-bit arm soft float support. For the files included only on arm, drop the test entirely. For others, test MACHINE_CPUARCH against arm. No functional change intended. File lists appear the same before / after the change.

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`
