2020-12-04	Atomics: Add 16 bit fetch + AND and fetch + OR signed integer operations	Julian Eisel
	I could use a 16 bit atomic fetch + AND for D9719. The alternative would be to turn a `short` into a `int` in DNA, which isn't a nice workaround. Also adds tests for the new functions.
2020-11-25	Atomics: Fix missing 64bit implementation for 32bit platforms	Sergey Sharybin
	Blender uses 64bit atomics to manipulate SessionUUID, and these atomics were not defined on any of 32bit platforms. While official support is limited to 64bit platforms only, the code should not make assumptions about bitness or endianess, in terms that there should be codepaths and fallback (or provision of them) for 32bit platforms. This change makes 64bit atomic functions defined for all platforms. The atomic_test was compiled and successfully tested on i686 and armv7l platforms. The rest of compilation process of Blender will be very tedious, so that was not done. This change is essential, but not necessarily enough to make Blender compilable on i686 (ability to compile Blender on 32bit platforms was lost during the 2.91 development). This is a functional part of original fix done by Brecht in D9577.
2020-11-25	Atomics: Cleanup, move defines closer to usage	Sergey Sharybin
	There is a special defines block needed for ARM on Linux. Move it from public header to an implementation file. No functional changes. This is a non-functional part of original fix done by Brecht in D9577.
2020-10-19	Spelling: It's Versus Its	Harley Acheson
	Corrects incorrect usage of contraction for 'it is', when possessive 'its' was required. Differential Revision: https://developer.blender.org/D9250 Reviewed by Campbell Barton

2019-04-17	ClangFormat: apply to source, most of intern	Campbell Barton
	Apply clang format as proposed in T53211. For details on usage and instructions for migrating branches without conflicts, see: https://wiki.blender.org/wiki/Tools/ClangFormat
2019-02-18	doxygen: add newline after \file	Campbell Barton
	While \file doesn't need an argument, it can't have another doxy command after it.
2019-02-06	Cleanup: remove redundant doxygen \file argument	Campbell Barton
	Move \ingroup onto same line to be more compact and make it clear the file is in the group.
2019-02-02	Cleanup: remove author/date info from doxy headers	Campbell Barton

2019-02-01	Cleanup: remove redundant, invalid info from headers	Campbell Barton
	BF-admins agree to remove header information that isn't useful, to reduce noise. - BEGIN/END license blocks Developers should add non license comments as separate comment blocks. No need for separator text. - Contributors This is often invalid, outdated or misleading especially when splitting files. It's more useful to git-blame to find out who has developed the code. See P901 for script to perform these edits.
2017-11-23	atomic_ops: add `atomic_cas_float` helper.	Bastien Montagne

2017-11-23	atomic_ops: add char versions of uint8_t atomic primitives.	Bastien Montagne

2017-11-23	atomic_ops: add signed versions of primitives.	Bastien Montagne
	Reason is motsly that dealing with type conversion in calling code is not great, makes it less readable, and can generate hidden bugs in case original type changes and atomic primitive calls are not updated accordingly...
2017-09-25	Add an 'atomic cas' wrapper for pointers.	Bastien Montagne
	Avoids having to repeat obfuscating castings everywhere...
2017-08-23	Fix implementation of atomic update max and move to a central location	Mai Lavelle
	While unlikely to have had any serious effects because of limited use, the previous implementation was not actually atomic due to a data race and incorrectly coded CAS loop. We also had duplicates of this code in a few places, it's now been moved to a single location with all other atomic operations.

2016-11-15	Atomics: Add some extra utility functions	Sergey Sharybin
	Also fixed semantic of fetch-and-add in assembler implementation, it seemed to not match the naming.

2016-11-08	Atomics: Add 32 bit version of fetch and AND/OR	Sergey Sharybin

2016-05-16	Atomic ops: add 'fetch_and_add_uint32' op.	Bastien Montagne
	Needed for next commit.
2016-05-09	Cleanup and refactor our atomic library.	Bastien Montagne
	This commit: * Removes most of all dirty internal details from public atomi_ops.h file, and move them into /intern private subdir. * Removes unused 'architectures' (__apple__ and jemalloc). * Split each implementation into its own file. * Makes use of C99's limits.h system header to determine pointer and int size, instead of using fix hardcoded list of architectures. * Introduces new 'faked' atomics ops for floats. Note that we may add a lot more real and 'faked' atomic operations over integers and floats (multiplication, division, bitshift, bitwise booleans, etc.), as needs arise.

2016-05-09	Atomics: Add atomic_fetch_and_or_uint8() function	Sergey Sharybin
	Hopefully it compiles on all platforms still..
2016-05-02	Fix compilation error on Armel architecture	Sergey Sharybin
	__GCC_HAVE_SYNC_COMPARE_AND_SWAP_n are not defined on this architecture for some reason, however those functions are available. Adding a workaround for newly used __sync_fetch_and_and() function.

	That's what MSDN tells you to do and that's how to solve the compilation error problem with it.
2016-01-27	atomic_ops: add atomic_fetch_and_and_uint8 wrapper.	Bastien Montagne
	Needed by incomming changes in pbvh.c. Note that we make it much simpler than for other primitives in this file - think we could revise its content to make it simpler one day...

2013-08-19	Apparently sizeof(unsigned) is 4 bytes on both 32 and 64 bit platforms	Sergey Sharybin
	For now assume sizeof(int) == 4 for all supported platforms, could be changed in the future. Added an assert to functions which depends on this this, so we'll easily notice bad things happening.

2013-08-19	Speedup for guarded allocator	Sergey Sharybin
	- Re-arrange locks, so no actual memory allocation (which is relatively slow) happens from inside the lock. operation system will take care of locks which might be needed there on it's own. - Use spin lock instead of mutex, since it's just list operations happens from inside lock, no need in mutex here. - Use atomic operations for memory in use and total used blocks counters. This makes guarded allocator almost the same speed as non-guarded one in files from Tube project. There're still MemHead/MemTail overhead which might be bad for CPU cache utilization
2013-08-19	Commit atomic operations file	Sergey Sharybin
	Not currently used, but needed for some further changes
