The SNB alt-mode math does the denorm and inf reduction even for a
"raw MOV" like we do for g0 message header setup, where we are moving
values that aren't actually floats. Just use UD type, where raw MOVs
really are raw MOVs.
Fixes glxgears since c52adfc2e1d130effea940e75690897eb5d3ceaa, but no
piglit tests had regressed(!)

This is a follow-up to commit ec51092a72e2dff1e9b1362d813fe4691cda89b7.

Had done this before pushing but forgot to amend, doh.

This gets my vote for most pointless extension of all time, I'm guessing
some driver could possibly optimise for this instead of counting it might
just get a true/false, but I'm not really sure.

Rename MAPI_GLAPI_SOURCES to MAPI_UTIL_SOURCES. Rename macro
MAPI_GLAPI_CURRENT to MAPI_MODE_UTIL. Update the comments to make it
clear that mapi may be used in two ways and how.
|
|
Try not to use macros to make u_current.h appear to be glapi.h. Use
u_current.h to implement glapi.h instead whenever possible.
|
|
TLS requires kernel >= 2.4.20. Per glapi.

|
NOTE: The 7.9 and 7.10 branches will need their builtins refreshed too.
Rather than cherry-picking this commit, run 'make builtins'.

These mistakenly computed 't' instead of t * t * (3.0 - 2.0 * t).
Also, properly vectorize the smoothstep(float, float, vec) variants.
NOTE: This is a candidate for the 7.9 and 7.10 branches.
|
|
No need to register function prototypes in the module now that we call
the C function pointer directly -- less LLVM objects lying around.
Limited testing with lp_test_format.
|
|
This is analogous to glsl_type::int_type and all the others.
|
|
Even though a bound texture stays bound when calling set_fragment_sampler_views,
it must be assigned a new cache region depending on the occupancy of other
texture units.
This fixes:

Thanks to Álmos <aaalmosss@gmail.com> for finding the bug in the code.

We don't support it.

With swizzling done at the end of texture sampling, we can greatly
simplify swizzling of the border color.
Fixes http://bugs.freedesktop.org/show_bug.cgi?id=32460
|
|
We need to keep using the pipe_get_tile_swizzle() even though there's
no swizzling because we need to explicitly pass in the surface format.

constants. For the 7.9 and 7.10 branches as well.

The only mismatch between the two is that we have to clear the
destination's alpha to 1.0. Fixes WOW performance on my Ironlake,
from a few frames a second to almost playable.
|
|
Before, we were going off of a couple of known (hopeful) matches
between internalFormats and the cpp of the read buffer. Instead, we
can now just look at the gl_format of the two to see if they match.
We should avoid bad blits that might have been possible before, but
also allow different internalFormats to work without having to
enumerate each one.
|
|
The blit that follows appears in the command stream so it's serialized
with previous rendering. Any queued vertices in the tnl layer were
already flushed up in mesa/main/.
|
|
Not fixing a particular bug, just noticed by code inspection.
|
|
Create a constant int pointer to the C function, then cast it to the
function's type. This avoids using trampoline code which seem to be
inadvertantly freed by LLVM in some situations (which leads to segfaults).
The root issue and work-around were found by José.

This matches how we did the math instructions pre-gen6, though it
applies to non-math as well.
Fixes vp1-LIT test 2 (degenerate case: 0 ^ 0 -> 1)

We have to use the non-IEEE compliant version of MUL here, since
log2(0) is -inf, and 0 * -inf is NaN in IEEE arithmetic.

Can't get away from referencing upload buffer as after flush a vertex buffer
using the upload buffer might still be active. Likely need to simplify the
pipe_refence a bit so we don't waste so much cpu time in it.
