6e778a7efd SPDX: license IDs for some ISC-related files. 2017-12-08 15:57:29 +00:00
Pedro F. Giffuni
e58eb3c437 include: General further adoption of SPDX licensing ID tags.
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.

7e3327be32 Add missing va_list to <wchar.h>.
It looks like va_list should always be defined when XSI is enabled. It
moved over to the POSIX base in the 2008 edition.

448f5f73dc include: Remove checks for __BSD_VISIBLE where redundant with __XSI_VISIBLE
or __POSIX_VISIBLE.

Whenever <sys/cdefs.h> sets __BSD_VISIBLE to non-zero, it also sets
__POSIX_VISIBLE and __XSI_VISIBLE to the newest version supported.

No functional change is intended.

9240031ac6 Add an implementation of open_memstream() and open_wmemstream(). These
routines provide write-only stdio FILE objects that store their data in a
dynamically allocated buffer.  They are a string builder interface somewhat
akin to a completely dynamic sbuf.

74dc547e24 Make the wchar_t type machine dependent.
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.

82dd5016bd Cleanup of xlocale:
- Address performance regressions encountered by das@ by caching per-thread
  data in TLS where available.
- Add a __NO_TLS flag to cdefs.h to indicate where not available.
- Reorganise the xlocale.h definitions into xlocale/*.h so that they can be
  included from multiple places.
- Export the POSIX2008 subset of xlocale when POSIX2008 says it should be
  exported, independently of whether xlocale.h is included.
- Fix the bug where programs using ctype functions always assumed ASCII unless
  recompiled.
- Fix some style(9) violations.

544048ecef Add a function attribute called `__malloc_like', which informs gcc
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. Note that gcc already
performs this optimization automatically for any function called
`malloc', `calloc', `strdup', or `strndup' unless -fno-builtins is
used.

12eb46c8bb Change the definition of NULL on ia64 (for LP64 compilations) from
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...

abbd890233 o Merge <machine/ansi.h> and <machine/types.h> into a new header
called <machine/_types.h>.
o <machine/ansi.h> will continue to live so it can define MD clock
  macros, which are only MD because of gratuitous differences between
  architectures.
o Change all headers to make use of this.  This mainly involves
  changing:
    #ifdef _BSD_FOO_T_
    typedef	_BSD_FOO_T_	foo_t;
    #undef _BSD_FOO_T_

  to:
    #ifndef _FOO_T_DECLARED
    typedef	__foo_t	foo_t;
    #define	_FOO_T_DECLARED
