SampleWindow底部的plane，把创建参数改成如下，会出现如图的bug
：

        planar_mesh = create_planar(
            hsr.get(), 
            vec3(-3.0f, -1.0f, -3.0f), 
            vec3(6, 0.0f, 0.0f), 
            vec3(0.0f, 0.0f, 6),
            1, 1, true
            );
原来的参数是
        planar_mesh = create_planar(
            hsr.get(), 
            vec3(-3.0f, -1.0f, -3.0f), 
            vec3(0.5f, 0.0f, 0.0f), 
            vec3(0.0f, 0.0f, 0.5f),
            20, 20, true

Constant expression could be translated to llvm value tree.
In this issue, we need implements following things:

 - Semantic analysis:
  - Make sure the expression is a constant expression. Now we need support literal constant and expression composited by it only. Constant variable consider later.
  - Translate value to llvm supported, and save them in a instance of class "constant semantic info"

 - Code generation:
  - translate literal constant value to llvm::Value object, and construct the expression tree.

 - Write test about it.

And the type of literal constant we only support int32 & uint32.
More types support will be added later.

Current presenters are used by #ifdef. It'll be too complex if more
presenters are added. Put one presenter into a DLL project and loads at
runtime can solve this problem.

Hi,

I ported your idea of SystemInfo.cmake to SOCI project
(here is my version 
https://github.com/denisarnaud/soci/blob/master/src/cmake/SociSystemInfo.cmake)
and I notice that GCC_VERSION variable is not set on Unix.

This variable is used in line 58

http://code.google.com/p/softart/source/browse/trunk/sasl/build/cmake/SystemInfo
.cmake?r=368#58

but GCC is queried for version only for MinGW in line 40:

http://code.google.com/p/softart/source/browse/trunk/sasl/build/cmake/SystemInfo
.cmake?r=368#40

Simply, it only needs to move the exec_program from if(MINGW) somewhere at the 
top of the script and change the condition to if(MINGW OR UNIX).

Also, this

... "gcc-"${GCC_VERSION})

should read

"gcc-${GCC_VERSION}")

otherwise there is a space between hyphen and version number.

Thanks for the very nice idea of this script!

While the tile_size changed from 256 to 32, the memory usage will
improvement very quickly( about 100 MB per second ).

maybe there are some memory leaks on clipping.

user file of vs2010 was changed from vs200x. so the corresponding cmake
section as following may be updated.

function(ogre_create_vcproj_userfile TARGETNAME)
  if (MSVC)
    configure_file(
      ${CMAKE_HOME_DIRECTORY}/cmake/VisualStudioUserFile.vcproj.user.in
      ${CMAKE_CURRENT_BINARY_DIR}/${TARGETNAME}.vcproj.user
      @ONLY
    )
  endif ()
endfunction(ogre_create_vcproj_userfile)

otherwise the debugging target is wrong.

and another question is that the rc file is not included in the project. It
is so strange... But we will need a solution yet.

Thanks for attention.

Add type conversation support to llvm code generation and semantic analysis.

First, we will implement type conversation between sasl buildin types.
Int-Int conversation is good for starting.

1. buildin scalar type conversations.
2. buildin vector/matrix type conversations.
3. customized type conversations.

DepthStencil state, Sampler state, Blend state and Rasterizer state should
be modified to D3D10 style.
1. Each state object have responding a desc struct.
2. A state object can't be changed after its inited by the desc struct.

We need to translate buildin_type to llvm::Type*.

Two steps we work with issue:
1. Translate buildin types which is correspond to llvm basic types.
2. Translate complex types.

PARENT Issue 22

We can do it as following steps:
  1. Add a function w/o parameter and void return type.
  2. Change the function sig to return a integer.
  3. Return a constant integer. Before do it, we need a jit tester.
  4. Add parameter a and b, return a + b. a & b are integers.
  5. Do other things. We will create another branch to do it.

Supports MSAA, SSAA, CSAA. Sampling pattern is customable. 

generated code can simulate SIMD execution.

We can compare two nodes who have the same subnodes by recursive comparison 
operation.

I found that the current name of this project is not search-engine friendly. I 
think we need a new name before the first release of this project.
If you have any idea, please let me know, via email or comment on this issue.

Following tips may help you:
  - It's a high frequenty used word in english or other latin language;
  - Less than 10 characters;
  - Nouns or Adjective + Nouns is better;
  - Prefer to concrete things in real world, or a common concept for logo design;
  - Implicit or explicit related to color, drawing or rendering concept is a good idea.

Thank you for paticipation, and don't hesitate to ask me if you have any 
question or advise.

CMake缺乏FreeImage Library导致FreeImage找不到Lib链接。
注意FreeImage的Library是分x86，x64 / vs8，vs9 的。

softart\eflib\include\pool.h
这个类中的recycled_pool，分配内存会当机。
重现方法，用SampleWindow渲染10次box：

        for(float i = 0 ; i < 10 ; i ++)
        {
            mat_translate(world , -0.5f + i * 0.5 , 0 , -0.5f 
+  i * 0.5);
            mat_mul(wvp, mat_mul(wvp, proj, view), world);
            pvs->set_constant(_T("WorldViewProjMat"), &wvp);
            box_mesh->render();
        }

JIT engine is need for testing generated code.
It is the prototype, and prefer to be reused in SASL JIT Engine.

Do semantic analysis and convert syntax_tree::program to llvm::module.
PARENT Issue 21
PARENT Issue 22

Add function name mangling to semantic analysis.

PARENT Issue 41

Create a structure combinator.

PARENT: Issue 20

1. A vertex bounded sample
2. A sample using stencil buffer

new Bitmap returns NULL.

1. Add semantic analysis to parameter & test it.
2. Add code generation to parameter & test it.

Supports Anistropic Filtering (AF). The best choise currently is EWA-based AF.

Following need to be implemented:

1. If-then-else statement.
2. While-do statement.
3. Do-while statement.
4. For statement.

rc file is marked as "Does not participate in build" in VS2010 project.
It's a cmake issue. All rc files should be selected as "Resource Compiler"
in "Item type" manually.

syntax tree combinator is a generator for creating a syntax tree manual.
And semantic action invoked by parser can use it also.

Implement the rasterizer in LRB paper.

Generate platform-dependent code from syntax tree.

Since better reuse, we refactory structure of code related to test cases.
Now tests be composited by 2 parts.
1. test configuration and data files located in test/test_resources.
2. objects we want to test. it is located in path test/test_cases.
3. test suites. one test suite is organized by an project. located in 
test/<test_project_name>
4. regression test. regression test includes all tests. It should be executed 
when regressing or integration. the code is in test/regression_test.

Constant expression could be translated to llvm value tree.
In this issue, we need implements following things:

 - Semantic analysis:
  - Make sure the expression is a constant expression. Now we need support literal constant and expression composited by it only. Constant variable consider later.
  - Translate value to llvm supported, and save them in a instance of class "constant semantic info"

 - Code generation:
  - translate literal constant value to llvm::Value object, and construct the expression tree.

 - Write test about it.

And the type of literal constant we only support int32 & uint32.
More types support will be added later.

Add initializer & function combinators.

Overall, four parts need to be implemented.

1. Statements,
2. Delcarations,
3. Type specifiers,
4. Expressions.


But we want to complete declaration translation first.

And corresponded tests need to added into test cases.

In CMakeLists.txt, adds
* Disable warning C4819
* Warning level increase to 4

Design and impl API for code compilation and JIT.

The semantic tests have to be migrated to fit semantic analysis.

The origin version semantic was extracted from syntax node,
and in new version, the semantic must get from symbol.
So symbol tests are pre-requried by others.

Function overload is the base of type promotion.

We need 2 mechanisms to support it:

1. Type implicit conversation
2. Name mangling

Following steps are possible way to implement it:

1. Implement name mangling.
2. Implenent implicit type conversation. It is also the sub-part of type 
conversation.
3. Write code for function prototype chosen.

Finish semantic anaysis of softart.
