* stand: kick out quad.hKyle Evans2019-08-151-0/+16
| | | | | | | | | | | | | | Use quad.h from libc instead for the time being. This reduces the number of nearly-identical-quad.h we have in tree to two with only minor changes. Prototypes for some *sh*di3 have been added to match the copy in libkern. The differences between the two are likely few enough that they can perhaps be merged with little additional effort to bring us down to 1. MFC after: 3 days Notes: svn path=/head/; revision=351078

* General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-2029-0/+58
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 3-Clause license. 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. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point. Notes: svn path=/head/; revision=326025
* Renumber copyright clause 4Warner Losh2017-02-2829-29/+29
| | | | | | | | | | | | Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

* Remove MK_ARM_EABI, the armeb issues have been fixed. The code to supportAndrew Turner2014-10-011-1/+1
| | | | | | | | | | | | | | | the oabi is still in the tree, but it is expected this will be removed as developers work on surrounding code. With this commit the ARM EABI is the only supported supported ABI by FreeBSD on ARMa 32-bit processors. X-MFC after: never Relnotes: yes Differential Revision: https://reviews.freebsd.org/D876 Notes: svn path=/head/; revision=272350
* Replace use of ${.CURDIR} by ${LIBC_SRCTOP} and define ${LIBC_SRCTOP}Marcel Moolenaar2014-03-041-2/+2
| | | | | | | | | | | | | | 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.

* Export quad symbols. They were previously commented out. These symbolsDaniel Eischen2007-05-311-6/+6
| | | | | | | | | | | | really shouldn't be exported since they should be pulled from libgcc, but the build of some applications is broken and they expect to see them in libc. glibc exports these symbols, although Solaris doesn't appear to, so export them for compatibility's sake.
