* Add CFI start/end proc directives to arm64, i386, and ppcConrad Meyer2020-12-051-4/+15
| | | | | | | | | | | | | | Follow-up to r353959 and r368070: do the same for other architectures. arm32 already seems to use its own .fnstart/.fnend directives, which appear to be ARM-specific variants of the same thing. Likewise, MIPS uses .frame directives. Reviewed by: arichardson Differential Revision: https://reviews.freebsd.org/D27387 Notes: svn path=/head/; revision=368354

* sys: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-201-0/+2
| | | | | | | | | | | | | | | | | 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=326023
* Renumber copyright clause 4Warner Losh2017-02-281-1/+1
| | | | | | | | | | | | 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.

* libc: Access _logname_valid more efficiently.Jilles Tjoelker2013-08-171-1/+2
| | | | | | | | | | | | | | The variable _logname_valid is not exported via the version script; therefore, change C and i386/amd64 assembler code to remove indirection (which allowed interposition). This makes the code slightly smaller and faster. Also, remove #define PIC_GOT from i386/amd64 in !PIC mode. Without PIC, there is no place containing the address of each variable, so there is no possible definition for PIC_GOT. Notes: svn path=/head/; revision=254463

| | | | | | | | | | | | | | | | | | under way to move the remnants of the a.out toolchain to ports. As the comment in src/Makefile said, this stuff is deprecated and one should not expect this to remain beyond 4.0-REL. It has already lasted WAY beyond that. Notable exceptions: gcc - I have not touched the a.out generation stuff there. ldd/ldconfig - still have some code to interface with a.out rtld. old as/ld/etc - I have not removed these yet, pending their move to ports. some includes - necessary for ldd/ldconfig for now.
