* libc/softfloat: we don't export _fp[gs]et* symbolsBrooks Davis2024-03-133-16/+0
| | | | | | | | | | Remove attempts to use NetBSD __weak_alias macros to export _-prefixed versions of various fp[sg]et* symbols under softfloat. __weak_alias isn't defined so we didn't export them and thus the Symbol.map entries were wrong.

* libc: further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-256-0/+12
| | | | | | | | | | | | | | | 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=326193

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | to mistakes from day 1, it has always had semantics inconsistent with SVR4 and its successors. In particular, given argument M: - On Solaris and FreeBSD/{alpha,sparc64}, it clobbers the old flags and *sets* the new flag word to M. (NetBSD, too?) - On FreeBSD/{amd64,i386}, it *clears* the flags that are specified in M and leaves the remaining flags unchanged (modulo a small bug on amd64.) - On FreeBSD/ia64, it is not implemented. There is no way to fix fpsetsticky() to DTRT for both old FreeBSD apps and apps ported from other operating systems, so the best approach seems to be to kill the function and fix any apps that break. I couldn't find any ports that use it, and any such ports would already be broken on FreeBSD/ia64 and Linux anyway. By the way, the routine has always been undocumented in FreeBSD, except for an MLINK to a manpage that doesn't describe it. This manpage has stated since 5.3-RELEASE that the functions it describes are deprecated, so that must mean that functions that it is *supposed* to describe but doesn't are even *more* deprecated. ;-) Note that fpresetsticky() has been retained on FreeBSD/i386. As far as I can tell, no other operating systems or ports of FreeBSD implement it, so there's nothing for it to be inconsistent with.
