This quiets a compiler warning, (and ensures a segmentation fault rather
than memory corruption if this variable is written through before being
initialized elsewhere).
|
|
While bootstrapping the dependencies, make will see the "include depend"
directive before the depend file has been created. To avoid a spurious
warning in this case we use "-include" instead, (which differs precisely
in the fact that it will not emit a diagnostic if the named file does
not exist).

Based on the two recent changes to program_lexer.l.
|
|
This avoids two "function defined but not used" warnings. For the yyinput
function we define YY_NO_INPUT which tells flex to simply not generate this
function.
For unput, we add a call to this function, but inside a while(0) so
that it will quiet the warning without actually changing any
functionality.
|
|
Add declarations for two functions generated in the flex ouput. It
would be nicer if flex simply declared these generated functions as
static, but for now we can at least avoid the warning this way.

Set sampler max_lod to avoid sampling the 1x1 and 2x2 mipmap levels.
Fixes piglit line-aa-width test, fd.o bug 29160.

Instead of one big boolean indicating indirect addressing, use a
bitfield indicating which register files are accessed with indirect
addressing.
Most shaders that use indirect addressing only use it to access the
constant buffer. So no need to use an array for temporary registers
in this case.

As with indexing the const buffer, the ADDR reg may have totally
different values for each element. Need to use a gather operation.
|
|
|
|
|
|
This used to be a somewhat packed struct, but no longer. Remove the
last remaining bitfield tag.
|
|
|
|
The previous code assumed that all elements of the address register
were the same. But it can vary from pixel to pixel or vertex to
vertex so we must use a gather operation when dynamically indexing
the constant buffer.
Still need to fix this for the temporary register file...

If max_index=0xffffffff and elt_bias > 0 the test for
elt_bias + max_index >= DRAW_PIPE_MAX_VERTICES
was wrong. Check earlier if max_index=0xffffffff and do the
"fail" case.
This fixes the piglit draw-elements-base-vertex test (and probably
some other things).

When defining mipmap level 'L' and level L-1 exists and the new level's
internalFormat matches level L-1's internalFormat, then use the same hw
format. Otherwise, do the regular ctx->Driver.ChooseTextureFormat() call.
This avoids a problem where we end up choosing different hw formats for
different mipmap levels depending on how the levels are defined (glTexImage
vs. glCopyTexImage vs. glGenerateMipmap, etc).
The root problem is the ChooseTextureFormat() implementation in some
drivers uses the user's glTexImage format/type parameters in the choosing
heuristic. Later mipmap levels might be generated with different calls
(ex: glCopyTexImage()) so we don't always have format/type info and the
driver may choose a different format.
For more background info see the July 2010 mesa-dev thread "Bug in
_mesa_meta_GenerateMipmap"

Only refresh the fake front buffer if there is one, and only destroy the region
once.
Fixes X11 protocol errors reported by 'mcgreg' on IRC.

Mainly, the type of __GLXdisplayPrivateRec::screenConfigs has changed
from "__GLXscreenConfigs *" to "__GLXscreenConfigs **".
|

The extension has been removed in
22266c391fbe17603b15a83d4ccf5fa9455ccf8d.

We do this in the X server for DRI2.
|
|
|
|
The XIDs are display wide so the natural location of the hash is here.
This way we don't have to lookup in each of the screen hashes.
|
|
|
|
The DRI2 protocol for ust, msc and sbc are unsigned but the extensions
talk about int64_t. Do a little dance to make the compiler shut up.

The extension never worked, the implementation returns GLX_BAD_CONTEXT
when enabling the frame tracking.

Only r200 implemented it.

GLXscreenConfigs is badly named and a dumping ground for a lot of stuff.
This patch creates private screen structs for the dri drivers and moves
some of their fields over there.
|
|
Enough is enough.

This saves a superfluous flush and a create/destryo region.
