Subject: [PATCH 03/82] glsl: implement loop unrolling for simple 'for' loops

Loops such as this will be unrolled:
  for (i = 0; i < 4; ++i) {
      body;
  }
where 'body' isn't too large.

This also helps to fix the issue reported in bug #19190.  The problem there
is indexing vector types with a variable index.  For example:
  vec4 v;
  v[2] = 1.0;  // equivalent to v.z = 1.0
  v[i] = 2.0;  // variable index into vector!!

Since the for-i loop can be unrolled, we can avoid the problems associated
with variable indexing into a vector (at least in this case).

Subject: [PATCH 19/82] mesa: Remove _Active and _UseTexEnvProgram flags from
 fragment programs.

There was a note in state.c about _Active deserving to die, and there were
potential issues with it due to i965 forgetting to set _UseTexEnvProgram.
Removing both simplifies things.

Subject: [PATCH 23/82] glsl: fix broken +=, -=, *=, /= operators

These functions need to return the final computed value.
Now expressions such as a = (b += c) work properly.
Also, no need to use __asm intrinsics in these functions.  The resulting
code is the same when using ordinary arithmetic operators and is more legible.

+
+<p>
+Mesa 7.2 is a stable release fixing bugs found in 7.1, which was a
+new development release.
+</p>
+<p>
+Mesa 7.2 implements the OpenGL 2.1 API, but the version reported by
+glGetString(GL_VERSION) depends on the particular driver being used.
+Some drivers don't support all the features required in OpenGL 2.1.
+</p>
+<p>
+Note that this version of Mesa does not use the GEM memory manager.
+The master branch of git uses GEM.
+The prototype DRI2 code that was in 7.1 has also been removed.
+</p>
+<p>
+DRM version 2.3.1 should be used with Mesa 7.2

+<li>Fixed some issues with glBindAttribLocation()
+<li>Fixed crash in _tnl_InvalidateState() found with Amira (bug 15834)
+<li>Assorted bug fixes for Ming build

+<ul>
+<li>Updated SGI header files with new license terms.

+<h2>To Do (someday) items</h2>
+<ul>
+<li>Remove the MEMCPY() and _mesa_memcpy() wrappers and just use memcpy().
+Probably do the same for malloc, calloc, etc.
+The wrappers were useful in the past for memory debugging but now we
+have valgrind.  Not worried about SunOS 4 support anymore either...
+<li>Switch to freeglut
+<li>Fix linux-glide target/driver.

-As of February 2008 the driver supports smooth/flat shaded triangle rendering
-with Z testing and simple texture mapping.
-Simple demos like gears run successfully.
-To test texture mapping, try progs/demos/texcyl (press right mouse button for
-rendering options).
+As of October 2008, the driver runs quite a few OpenGL demos.
+Features that work include:
 </p>
+<ul>
+<li>Point/line/triangle rendering, glDrawPixels
+<li>2D, NPOT and cube texture maps with nearest/linear/mipmap filtering
+<li>Dynamic SPU code generation for fragment shaders, but not complete
+<li>Dynamic SPU code generation for fragment ops (blend, Z-test, etc), but not complete
+<li>Dynamic PPU/PPC code generation for vertex shaders, but not complete
+</ul>
+<p>
+Performance has recently improved with the addition of PPC code generation
+for vertex shaders, but the code quality isn't too great yet.
+</p>

+Another bottleneck is SwapBuffers.  It may be the limiting factor for
+many simple GL tests.

+
+<H2>Debug Options</H2>
+
+<p>
+The CELL_DEBUG env var can be set to a comma-separated list of one or
+more of the following debug options:
+</p>
+<ul>
+<li><b>checker</b> - use a different background clear color for each SPU.
+   This lets you see which SPU is rendering which screen tiles.
+<li><b>sync</b> - wait/synchronize after each DMA transfer
+<li><b>asm</b> - print generated SPU assembly code to stdout
+<li><b>fragops</b> - emit fragment ops debug messages
+<li><b>fragopfallback</b> - don't use codegen for fragment ops
+<li><b>cmd</b> - print SPU commands as their received
+<li><b>cache</b> - print texture cache statistics when program exits
+</ul>
+<p>
+Note that some of these options may only work for linux-cell-debug builds.
+</p>
+
+<p>
+If the GALLIUM_NOPPC env var is set, PPC code generation will not be used
+and vertex shaders will be run with the TGSI interpreter.
+</p>
+<p>
+If the GALLIUM_NOCELL env var is set, the softpipe driver will be used
+intead of the Cell driver.
+This is useful for comparison/validation.

Subject: [PATCH 33/82] glsl: make minimum struct size = 2, not 1

1-component structs such as "struct foo { float x; }" could get placed at
any position within a register.  This caused some trouble computing the
field offset which assumed all struct objects were placed at R.x.
It would be unusual to hit this case in normal shaders.

Subject: [PATCH 36/82] glsl: force creation of new scope for for-loop body

Fixes regression in progs/demos/convolution.c due to loop unrolling.
This also allows the following to be compiled correctly:
for (int i = 0; i < n; i++) {
   int i;
   ...
}
This fix is a bit of a hack, however.  The better fix would be to change
the slang_shader.syn grammar.  Will revisit that...

Subject: [PATCH 59/82] i965: fix broken ARB fp fog options

Just call _mesa_append_fog_code() if the fragment program's FogOption is
not GL_NONE.
This allows us to remove some unnecessary i965 fog code.
Note, the arbfplight.c demo can be used to test this (see DO_FRAGMENT_FOG).

Subject: [PATCH 60/82] i965: fix broken glBitmap + depth test

When we use the do_blit_bitmap() function, it seems the fragment Z is always
1.0.  If depth testing is on, that means that bitmap fragments are often
occluded by other rendering.  So, the bitmap doesn't appear even if
rasterpos.Z==0.
The fix is to use the intel_texture_bitmap() path when depth testing is on.
Also, fix the incorrect Z coordinate.  It needs to be an NDC value in [-1,1].

Subject: [PATCH 64/82] Add language about implicit flush and command
 completion

Copied language from the glXSwapBuffers manual page about the implicit
glFlush and expected command completion.  This just codifies what
people already expect from glXCopySubBufferMESA.  The intention of
this command is to work like glXSwapBuffers but on a sub-rectangle of
the drawable.

Subject: [PATCH 77/82] Treat image units and coordinate units differently.

Previously MaxTextureUnits was used to validate both texture image
units and texture coordinate units in fragment programs.  Instead, use
MaxTextureCoordUnits for texture coordinate units and
MaxTextureImageUnits for texture image units.

Fixes bugzilla #19468.
