Make sure we do not run into the classic ABA problem on buffer object bind,
reusing this name and may be never rebind since we get an new name
that was just deleted and never rebound in between.
The explicit rebinding to the debault object in the current context
prevents the above in the current context, but another context
sharing the same objects might suffer from this problem.

- Fix _GNUC__ typo in both checks
- Fix logic error in check for gcc < 3.4 that breaks for gcc 2.x & older
Without this fix, builds with gcc 3.4.x end up depending on undefined
_mesa_bitcount instead of gcc's __builtin_popcount.
NOTE: This is a candidate for the stable branches.

When there is no ARB_vertex_program program enabled, the Current

From the GL 2.1 specification, page 114 (page 128 of the PDF):
"The version of PixelStore that takes a floating-point value
may be used to set any type of parameter; if the parameter is
boolean, then it is set to FALSE if the passed value is 0.0
and TRUE otherwise, while if the parameter is an integer, then
the passed value is rounded to the nearest integer."

v2: quote the spec; explicitly exclude the GL_BITMAP case to make code
more readable. (comments from Ian)
v3: Cast the offset by GLintptr to remove the compile warning(comments

I also found that I should use _mesa_sizeof_packed_type() instead,
as it includes packed pixel type, like GL_UNSIGNED_SHORT_5_6_5.

This hook allows the driver to prepare for a glBegin/glEnd.
i965 will use the hook to avoid avoid recursive calls to FLUSH_VERTICES
during a buffer resolve meta-op.
Detailed Justification
----------------------
When vertices are queued during a glBegin/glEnd block, those vertices must
of course be drawn before any rendering state changes. To enusure this,
Mesa calls FLUSH_VERTICES as a prehook to such state changes. Therefore,
FLUSH_VERTICES itself cannot change rendering state without falling into
a recursive trap.
This precludes meta-ops, namely i965 buffer resolves, from occuring while
any vertices are queued. To avoid that situation, i965 must satisfy the
following condition: that it queues no vertex if a buffer needs resolving.
To satisfy this, i965 will use the PrepareExecBegin hook to resolve all
buffers on entering a glBegin/glEnd block.
--------
v2: Don't add dd_function_table::CleanupExecEnd. Anholt and I discovered
that hook to be unnecessary.

It was previously under gpu_shader4, but I'm pretty sure everyone's

This is a step towards providing a direct route for drivers accepting
GLSL IR for codegen. Perhaps more importantly, it runs the fixed
function fragment program through the GLSL IR optimization. Having
seen how easy it is to make ugly fixed function texenv code that can
do unnecessary work, this may improve real applicatinos.
|
|
|
|
|
|
|
|
| |
On converting fixed function programs to generate GLSL, the linker
became cranky that we were trying to make something that wasn't a
linked vertex+fragment program. Given that the Mesa GLES2 drivers
also support desktop GL with EXT_sso, just telling the linker to shut
up seems like the easiest solution.
|
|
|
|
|
| |
This is a slight simplification on the way to actually generating GLSL
fragment shaders.

save_CompressedTex(Sub)Image
Introuduce a simple function called copy_data to do the image data copy
stuff for all the save_CompressedTex*Image function. The function check
the NULL data case to avoid some potential segfault. This also would
make the code a bit simpler and less redundance.

This fixes failures found with the new piglit texsubimage test.
Two things were broken:
1. The dxt code doesn't handle sources images where width != row stride.
Check for that and take the _mesa_make_temp_ubyte_image() path to get
an image where width = rowstride.
2. If we don't take the _mesa_make_temp_ubyte_image() path we need to
take the source image unpacking parameters into account in order to
get the proper starting memory address of the source texels.
Note: This is a candidate for the 7.11 branch.

The i965 driver already had a function to count bits in a 64-bit uint
(brw_count_bits()), but it was buggy (it only counted the bottom 32
bits) and it was clumsy (it had a strange and broken fallback for
non-GCC-like compilers, which fortunately was never used). Since Mesa
already has a _mesa_bitcount() function, it seems better to just
create a _mesa_bitcount_64() function rather than special-case this in
the i965 driver.
This patch creates the new _mesa_bitcount_64() function and rewrites
all of the old brw_count_bits() calls to refer to it.
