same variable used for 2 different temp registers
fixes e.g. glsl/bump

So if we don't actually emit an atom to the hw because we don't
need it in the current state (e.g. lighting related atoms when
lighting is off) then don't mark it as clean, because when
lighting gets switched on we won't emit it at all.
This fixes funky gears colors.

mesa core does it now. If only it did so for other entrypoints.

Bug #25921 -- clutter PBO usage gave unreliable results.

As with swrast, this fixes the default pixel center behavior which was
broken, and implements the previous behavior for integer. Fixes
piglit fp-arb-fragment-coord-conventions-none. The extension won't be
exposed until we get the GLSL part implemented.
The DRI1 origin_x/y parts are dropped since they're no longer relevant.
|
|
This brings swrast's support up to the state of gallium, and fixes the
default center behavior of fragment.position.xy in piglit
fp-arb-fragment-coord-conventions-none.
The extension is not enabled currently because the GLSL part of the
extension isn't supported, so piglit
glsl-arb-fragment-coord-conventions-define fails as would any serious
test of the GLSL part.

|
Merging was easier than cherry picking in this instance.

If GL_EXT_framebuffer_blit was not supported _mesa_DeleteFramebuffersEXT
would raise an error when deleting the currently bound framebuffer. This
because it tried to bind the default DRAW- and READ_FRAMEBUFFER separately.
This patch binds the default FRAMEBUFFER instead in that case.
Encountered in the fbo/fbo-copyteximage piglit test on R600.
Patch cleaned up a bit by Brian Paul.
|
|
Now that LOCK_HARDWARE is gone, we don't have a convenient place to
update the renderbuffers everywhere we need them. So grab new buffers
when we invalidate the old ones until we optimize things further.
|
|
If we determine that the 'end' parameter to glDrawElements() is out of
bounds, clamp it to the max legal index value.
|
|
Some apps are sloppy with their start/end values. Clamp them to
max possible values to prevent problems later.
|
|
Eric added some new code to check if offset < obj_size before computing
_MaxElement but my original code was still present afterward and it
clobbered the _MaxElement value.
Not sure if this came from a bad merge or what.

The server side does the throttling on our behalf now by putting the
client to sleep, so we don't need our previous hacks for limiting the
number of outstanding frames. Same effect as

done."
This reverts commit 7d4e674b212c9dc6408c13913a399bd4a2b9a1e3. It broke
throttling in the non-new-DRI2 case.

My commit eea6a7639f767b1d30b6ef1f91a9c49e3f3b78f0 does a memcpy of height
lines, but that's wrong because the texture has a block layout and we
must thus use the number of vertical blocks instead of the height.

Based on a patch by Xavier Chantry <chantry.xavier@gmail.com>:
If x+width or y+height is negative, then maxx or maxy will get a bogus value
when converting that to unsigned. Fix this by setting 0 as minimal value.
This was also triggered by teeworlds, but only with some combination of
resolution and map section. For example upper part of dm2 at 1280x1024.

Part of a patch from Xavier Chantry <chantry.xavier@gmail.com>
|
|
commit 53174afeeb introduced a portability change that converted GLint x,y
to GLuint. That breaks when x and y are negative, which seems to be allowed,
and which at least one game uses : teeworlds.
Rather than simply reverting the change, it seems possible to convert the
16bit unsigned to GLint so that comparisons are made between signed integers
instead. This hopefully does not break anything while keeping MSVC happy.

Make sure glapi headers are cleaned when "make clean". Make sure all
sources depend on subdirs-stamp-tmp so that sources/headers are
generated first.
subdirs-stamp-tmp will be removed after a successful build. It might be
a problem when a build fails. But it is much better than where we
currently are: glapi headers are never cleaned or re-generated.

read_rgba_span_x86.S uses the pseudo-ops .hidden and .type which are
not recognized on Mac OS X.
|

The .hidden directive is an unknown pseudo-op on Mac OS X.

The .type directive is an unknown pseudo-op on Mac OS X.
