they won't generate any useful conversion code for some of the new formats
but at least don't assert. Also needed some more hacks so they don't generate
code for some of the new formats, as gcc was not impressed.
Also declare unused channels as void, and change the scripts to not fail if
the first channel happened to be unused.
Needs serious fixing.

only the depth part is normalized, stencil part isn't.
|
|
These are needed for DX10 and/or OGL3.3.
This just adds the formats nothing handles them yet.
PIPE_FORMAT_R1_UNORM can't be used currently as it requires special filter.
Need to reclassify compressed formats at some point.
|
|
Not sure why we are open-coding these rather than using standard
library functions.

Needed for i915g, also fixed swizzle in draw_vs_aos_io.

This reverts commit f87a5f6499f51f651c2a9f2d4682875b22926905.

Suggested by Jose on the list, probably not perfect but will let me get
past this for now, testing with a fenced bufmgr on top of this, was slower,
Also this doesn't let you do the busy early exit optimisation either from
what I can see.

Refactor the code into two helper functions which compute the bit mask
and shift terms for Z and stencil. Plus add a bunch of new comments to
explain everything.

|
no longer used after all statetrackers have been converted.
|
|
|
|
We were mistakenly using the wrong data type for stencil values before.
|
|
The triangle rasterizer sets this field to indicate front/back-facing.
It gets passed into the generated fragment code as another parameter.
Used now for stencil front/back selection but will also be used for
fragment shaders in general (see TGSI_SEMANTIC_FACE).
With this commit two-sided stenciling mostly works but there's
still a bug or two...
|
|
|
|
Instead of passing an array, just pass two scalar values.
|
|
|
|
Most stencil demos look OK (modulo some unrelated rendering glitches).
Only single-sided stencil test works at this point.
There are probably some bugs to be found...

Was commented out before.

changes arguments of util_blit_pixels_tex and util_gen_mipmap to
struct pipe_sampler_view * instead of struct pipe_texture *.
|
|
This branch already seems to have the nv50_tex.c fix.

The llvm wrapper wasn't really an OS thing.
Use lp_bld.h for now but we eventually should rename/re-prefix all the
files/functions in the gallivm/ directory.
|
|
We were never returning -1 as a result. This fixes some inverted/flipped
faces with cube mapping.
|
|
Sampler views already hold references to those.
|
|
When min_lod==max_lod we don't need to go through all the work of
computing the lod from partial derivatives. This is hit by the mipmap
generation utility code.
|
|
|
|
Use the LOD value to determine whether to use the minification vs.
magnification filter.
All mipmap sampling modes work now.
|
|
|
|
LLVMBuildFPTrunc() should be used for double->float conversion, not
float->int conversion.
There should be a better way to compute floor(), ceil(), etc that doesn't
involve float->int->float conversion.

Quite a bit a hair pulling was involved...
