* Revert Make newly POSIX functions visibleStephen Hurd2025-03-201-5/+2
| | | | | | | | | | | | Summary: This reverts commit d7efac1be1441c122f7fb9de51a409172f21326c. This reverts commit 9d0eea9422d075c8a6924b33161d2d5abfb4072a. Some ports (specifically Python) define __BSD_VISIBLE themselves, so the change from __BSD_VISIBLE to __POSIX_VISIBLE >= 202405 makes them fail. Reported by: jrtc27, cperciva

* include: General further adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-251-0/+2
| | | | | | | | | | | | | | | 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=326192

* Make the wchar_t type machine dependent.Andrew Turner2012-06-241-4/+2
| | | | | | | | | | | | | | | | | This is required for ARM EABI. Section 7.1.1 of the Procedure Call for the ARM Architecture (AAPCS) defines wchar_t as either an unsigned int or an unsigned short with the former preferred. Because of this requirement we need to move the definition of __wchar_t to a machine dependent header. It also cleans up the macros defining the limits of wchar_t by defining __WCHAR_MIN and __WCHAR_MAX in the same machine dependent header then using them to define WCHAR_MIN and WCHAR_MAX respectively.

| | | | | | | | | | | | | | | | | that the annotated function returns a pointer that doesn't alias any extant pointer. This results in a 50%+ speedup in microbenchmarks such as the following: char *cp = malloc(1), *buf = malloc(BUF); for (i = 0; i < BUF; i++) buf[i] = *cp; In real programs, your mileage will vary.

* Change the definition of NULL on ia64 (for LP64 compilations) fromMarcel Moolenaar2003-12-071-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | an int constant to a long constant. This change improves consistency in the following two ways: 1. The first 8 arguments are always passed in registers on ia64, which by virtue of the generated code implicitly widens ints to longs and allows the use of an 32-bit integral type for 64-bit arguments. Subsequent arguments are passed onto the memory stack, which does not exhibit the same behaviour and consequently do not allow this. In practice this means that variadic functions taking pointers and given NULL (without cast) work as long as the NULL is passed in one of the first 8 arguments. A SIGSEGV is more likely the result if such would be done for stack-based arguments. This is due to the fact that the upper 4 bytes remain undefined. 2. All 64-bit platforms that FreeBSD supports, with the obvious exception of ia64, allow 32-bit integral types (specifically NULL) when 64-bit pointers are expected in variadic functions by way of how the compiler generates code. As such, code that works correctly (whether rightfully so or not) on any platform other than ia64, may fail on ia64. To more easily allow tweaking of the definition of NULL, this commit removes the 12 definitions in the various headers and puts it in a new header that can be included whenever NULL is to be made visible. This commit fixes GNOME, emacs, xemacs and a whole bunch of ports that I don't particularly care about at this time... Notes: svn path=/head/; revision=123257
