Thus, BeOS compatibility is preserved (and there is no risk of
breaking GCC5<->GCC2 interoperation on hybrid builds.)
This commit only makes the actual change, the build fixes are
in the next commit.
The atomic inlines were not implemented in a C89 safe way:
* Use of "static inline" not allowed, but static __inline__ is
* __inline__ is a GCC extension, but these are already in a __GNUC__
block (other compilers use a non-inline version)
* also fix a C++ style comment
This reverts commit 34dbbb65fd.
Instead, we can remove thos from HaikuBuildCompatibility and things will work fine, unless one try t build Haiku on BeOS (this isn't
supported anymore) or a very old Haiku which esdon't have those.
Pawel changed the implementation but I see no reason to make those available only from C++, so it must be an oversight.
Fixes building Haiku on Haiku which otherwise hits a mismatch in build compatibility headers.
If GCC knows what these functions are actually doing the resulting
code can be optimized better what is especially noticeable in case of
invocations of atomic_{or,and}() that ignore the result. Obviously,
everything is inlined what also improves performance.

* No need for the atomically changed variables to be declared as
volatile.
* Drop support for atomically getting and setting unaligned data.
* Introduce atomic_get_and_set[64]() which works the same as
atomic_set[64]() used to. atomic_set[64]() does not return the
previous value anymore.
Currently all debugger commands assume 32-bit pointers when formatting their
output. This means that on x86_64 the output is incorrectly formatted. Fixed
this by adding a B_PRINTF_POINTER_WIDTH definition (16 on 64-bit, 8 on
32-bit), and using this to correctly format the output. Not all commands have
been fixed yet, but all VM, slab, VFS, team, thread and image commands should
be correct.
- Added macro __HAIKU_ARCH_BITS specifying the architecture bitness (32/64)
(might be more convenient to use than __HAIKU_ARCH_{32,64}_BIT).
- Added macros __HAIKU_ARCH_PHYSICAL_BITS, __HAIKU_ARCH_PHYSICAL_{32,64}_BIT,
and the types __haiku_phys_[s]addr_t. The intention is to use separate
macros and types for virtual and physical addresses, since for some
architectures (e.g. x86 with PAE) those actually differ.
* sys/types.h, BeBuild.h, SupportDefs.h:
- Added types phys_[s]addr_t and respective printf() format macros.
- Added public macros B_HAIKU_BITS, B_HAIKU_PHYSICAL_BITS,
B_HAIKU_PHYSICAL_{32,64}_BIT.
Might break the build under older Haiku installations. Will test next.

B_USE_BUILTIN_ATOMIC_FUNCTIONS is defined most atomic_*() functions are
redefined as macros using the built-ins directly.
* Enabled that feature for the x86 build. Might work on other platforms as
well, but that needs to be tested.
No significant speedup for the -j8 Haiku image build.

system_time_nsecs(), returning the system time in nanoseconds. The function
is only really implemented for x86. For the other architectures
system_time() * 1000 is returned.

* Added FSSH_[S]SIZE_MAX to headers/private/fs_shell/fssh_types.h.
* Fixed various 64 bit compiler warnings. Nothing too serious, though.

and types.h. The idea is to provide a basic architecture/compiler
abstraction by defining types and macros that allow the posix/ and os/
headers to be mostly architecture/compiler agnostic.
* Adjusted the posix/ and os/ headers accordingly.
* <SupportDefs.h>: Introduced B_PRI* and B_SCN* macros similar to the PRI*
and SCN* macros defined in <inttypes.h>, just for the BeOS/Haiku [u]int*
types and some POSIX types (e.g. off_t, dev_t, ino_t) that don't have POSIX
macros. Also the B_PRI* and B_SCN* macros are available unconditionally,
unlike the <inttypes.h> macros, which require __STDC_FORMAT_MACROS to be
defined in C++ mode.

Make sure the comments are C style in headers that are included by POSIX
headers.
Thanks! Should fix#2870.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28598 a95241bf-73f2-0310-859d-f6bbb57e9c96
feel free to change that ;-)
* Cleaned up existing headers.
* Coding style guide update to BBufferIO (renamed m_* members to f*).

- SupportDefs.h only includes stdbool.h if included from C
- stdbool.h for C++ now includes a macro for "bool" as defined by that header
- stdbool.h does nothing if __bool_true_false_are_defined is already defined
- stdbool.h no longer defines a _Bool enum, but defines _Bool as unsigned char, as
previously done by SupportDefs.h (the previous version changed the size).
- The gensyscalls Jamfile now preprocesses its headers in C++ mode so that "bool"
stays "bool", and doesn't become _Bool.

SupportDefs.h now includes stdbool.h
This can break in some cases

renamed user_??? functions into the new _user_??? naming style.
changed implementation of PPC 64 bit atomic functions to use (un)lock_memory()
