* 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
* lib: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-262-0/+4
| | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326219
* 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.

Stop using __FreeBSD_ARCH_armv6__ and switch to __ARM_ARCH >= 6 in the couple of places in tree. clang already implements ACLE. Add a define that says we implement version 1.1, even though the implementation isn't quite complete. Notes: svn path=/head/; revision=269956

This could complicate future changes in the implementation of the floating-point emulation layer, so it seems best to have programs refer to the official fe* entry points in libm.

* Provide external definitions of all of the standardized functions inDavid Schultz2011-10-103-14/+45
| | | | | | | | | | | | | | | | | | | | fenv.h that are currently inlined. The definitions are provided in fenv.c via 'extern inline' declaractions. This assumes the compiler handles 'extern inline' as specified in C99, which has been true under FreeBSD since 8.0. The goal is to eventually remove the 'static' keyword from the inline definitions in fenv.h, so that non-inlined references all wind up pointing to the same external definition like they're supposed to. I am deferring the second step to provide a window where newly-compiled apps will still link against old math libraries. (This isn't supported, but there's no need to cause undue breakage.)

| | | | | | | | | | | | | fedisableexcept(), and fegetexcept(). These two sets of routines provide the same functionality. I implemented the former as an undocumented internal interface to make the regression test easier to write. However, fe(enable|disable|get)except() is already part of glibc, and I would like to avoid gratuitous differences. The only major flaw in the glibc API is that there's no good way to report errors on processors that don't support all the unmasked exceptions. Notes: svn path=/head/; revision=143708

It does not appear to be possible to cross-build arm from i386 at the moment, and I have no ARM hardware anyway. Thus, I'm sure there are bugs. I will gladly fix these when the arm port is more mature. Reviewed by: standards@ Notes: svn path=/head/; revision=130143
