* libc: Simplify soft-float on 32-bit armWarner Losh2023-02-141-1/+1
| | | | | | | | | | | | | 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. Sponsored by: Netflix Reviewed by: emaste Differential Revision: https://reviews.freebsd.org/D38582
* Support armv7 builds for userlandWarner Losh2017-10-051-1/+1
| | | | | | | | | | | | | | | | | | | 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.

* Correct an misunderstanding of MDSRCS.Brooks Davis2017-03-021-1/+1
| | | | | | | | | | | | | | | 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.

| | | | | | | | These are only exported for armv6hf as the soft-float ABIs have these in the softfloat Symbol.map file. Notes: svn path=/head/; revision=271179

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.

* Add the required __aeabi_* functions to libc.Andrew Turner2013-01-191-0/+2
| | | | | | | | The floating point functions are here rather than compiler-rt because the libc softfloat code allows us to set the rounding mode. Notes: svn path=/head/; revision=245655
