This reverts commit 8446f257b3e3ca4a3eb2c79bc357e46343e04e87.
|
|
If texture coordinates come from the vertex shader, there are always
4 components in the rasterizer input packet, but if the coordinates
are stuffed (like for point sprites), there are only 2 or 3 components
(based on GB_ENABLE) and if we rasterize more, it locks up.

When DRI2 swap buffer is pending (copy buffer not pageflipping)
we need to make sure we have the flush extension so radeon doesn't
resume rendering on the not yet blitted front buffer.
Modified version of Jerome's patch to add flush extension
in the correct place.
This prepares a possible fix for:

r600 doesnt need the same normalization as r700 - instead it requires
range to be truncated to -pi..pi
I left the range trunc also effective on r700 althouch according the docs
it has sufficent range (-512*PI, +512*PI). The instructions seem
to be used not too often to cause perf loss because of this
Based on patches and testing by Conn Clark and Alain Perrot

Apparently, we must always use integers to perform calculations,
otherwise the results won't match D3D's CxV8U8 definition.

this isn't used anywhere else yet.

Fixes glsl-mat-110.

Not sure if this will actually fix the issue, but it fixes the warning.

Getting tiling right has always been tricky.
There are so many subtle details...

This is the option that dumps shader source to files in the current
directory.
|
|
gcc and mesa master agree that this is OK.

mtypes.h does not use any symbols from compiler.h.
Also add the required headers for files that depended on symbols from
compiler.h but were indirectly including compiler.h through mtypes.h.
|
|
|
|
|
|
|
|
get.h only needs the GL headers.
|
|
Include compiler.h for INLINE symbol.
Include mtypes.h for GLcontext symbol.

Include mtypes.h for GLcontext symbol.

Linking brings in inlining of builtins, so we weren't catching the
(rcp(/sqrt(x)) -> rsq(x)) without it.

Include compiler.h for INLINE symbol.

This allows Mesa EGL to be compiled with eglext.h that does not define
EGL_MESA_screen_surface.

Include mtypes.h for GLcontext symbol.

So many problems here. One is that we can't do the quadrant handling
for all the channels at the same time, so we call the float(y, x)
version multiple times. I'd also left out the x == 0 handling. Also,
the quadrant handling was broken for y == 0, so there was a funny
discontinuity on the +x side if you plugged in obvious values to test.
I generated the atan(float y, float x) code from a short segment of
GLSL and pasted it in by hand. It would be nice to automate that
somehow.
Fixes:
glsl-fs-atan-1
glsl-fs-atan-2

This prevents using uninitialized data in _msea_glsl_error in some
cases, (including at least 6 piglit tests). Thanks to valgrind for
pointing out the problem!

Otherwise, ir_function_inlining will see the body of the function from
the unlinked version of the shader, which won't have had the lowering
passes done on it or linking's variable remapping.

Fixes a valgrind error.

With gl_program::IndirectRegisterFiles we can distinguish between indirect
addressing of constants vs. temporaries. In the case of temporaries,
declare all temps up front sequentially.
Fixes fd.o bug 29305.
|
|
Now drivers, etc. can know which register files are accessed with
indirect addressing. Before we just checked gl_program::NumAddressRegs
but didn't know if that was the constant buffer, temp regs, or what.
The only user of this new field so far will be the gallium state tracker.
