5a1954a5cb Drop platform support for Solaris & AIX
These platforms didn't see maintenance in years.
This commit just removes ifdef's & cmake check.

17d96ca2aa GuardedAlloc: safer MEM_SAFE_FREE
only instantiate the argument once,
so MEM_SAFE_FREE(array[i++]), won't cause incorrect behavior.

c86c9297dc Fix inconsistent types in guardealloc
This basically fixes mix of size_t and uintptr_t usages which might be different size.

a87fb34eda Use advantage of SSE2 instructions in gaussian blur node
This gives around 30% of speedup for gaussian blur node.

Pretty much straightforward implementation inside the node
itself, but needed to implement some additional things:

- Aligned malloc. It's needed to load data onto SSE registers
  faster. based on the aligned_malloc() from Libmv with
  some additional trickery going on to support arbitrary
  alignment (this magic is needed because of MemHead).

  In the practice only 16bit alignment is supported because
  of the lack of aligned malloc with arbitrary alignment
  for OSX. Not a bit deal for now because we need 16 bytes
  alignment at this moment only. Could be tweaked further
  later.

- Memory buffers in compositor are now aligned to 16 bytes.
  Should be harmless for non-SSE cases too. just mentioning.

4bd4037276 Lock-free memory allocator
Release builds will now use lock-free allocator by
default without any internal locks happening.

MemHead is also reduces to as minimum as it's possible.
It still need to be size_t stored in a MemHead in order
to make us keep track on memory we're requesting from
the system, not memory which system is allocating. This
is probably also faster than using a malloc's usable
size function.

Lock-free guarded allocator will say you whether all
the blocks were freed, but wouldn't give you a list
of unfreed blocks list. To have such a list use a
--debug or --debug-memory command line arguments.

Debug builds does have the same behavior as release
builds. This is so tools like valgrind are not
screwed up by guarded allocator as they're currently
are.

ccd2e4375a Fix compilation error after recent libmv change
- Tweaked typedefs in stdint so they match
  what we've got in BLI_sys_types (needed to
  explicitly tell sign to MSVC).

  Not so much harmful to be more explicit here,
  but we really better to have single stdint
  int blender.

- Tweaked allocations macros so MSVC is happy
  with structures allocation.

49bc310671 Move guarded objetc allocation to a guardedalloc header
Also made libmv-capi use guarded objetc allocation.
Run into some suspecious cases when it was not so
clear whether memory is being freed or not.

Now we'll know for sure whether there're leaks or not :)

Having this macros in a guardedalloc header helps
using them in other areas (for now it's OCIO and libmv,
but in the future it'll be more places).

2a8d76d734 add versions of MEM_reallocN, MEM_recallocN which take a string arg so new allocs have an ID, changing existing functions signatures would be too disruptive at the moment. 2013-08-03 17:53:41 +00:00

- enabling/disabling no longer prints in the terminal unless in debug mode.

433f871f0f bugfix [#24302] Ctrl+Click Extrude gets old mouse events
double click didnt check mouse distance moved so you could click twice in different areas of the screen very fast and generate a double click event which had old mouse coords copied into it but was sent to an operator set to run on single click (because the double click wasnt handled).

Also added MEM_name_ptr function (included in debug mode only), prints the name of allocated memory.
used for debugging where events came from.

cb89decfdc Merge of first part of changes from the apricot branch, especially
the features that are needed to run the game. Compile tested with
scons, make, but not cmake, that seems to have an issue not related
to these changes. The changes include:

* GLSL support in the viewport and game engine, enable in the game
  menu in textured draw mode.
* Synced and merged part of the duplicated blender and gameengine/
  gameplayer drawing code.
* Further refactoring of game engine drawing code, especially mesh
  storage changed a lot.
* Optimizations in game engine armatures to avoid recomputations.
* A python function to get the framerate estimate in game.

* An option take object color into account in materials.
* An option to restrict shadow casters to a lamp's layers.
* Increase from 10 to 18 texture slots for materials, lamps, word.
  An extra texture slot shows up once the last slot is used.

* Memory limit for undo, not enabled by default yet because it
  needs the .B.blend to be changed.
* Multiple undo for image painting.

* An offset for dupligroups, so not all objects in a group have to
  be at the origin.
