For depthstencil textures using separate stencil, we embedded a stencil
buffer in intel_texture_image. The intention was that the embedded stencil
buffer would be the golden copy of the texture's stencil bits. When
necessary, we scattered/gathered the stencil bits between the texture
miptree and the embedded stencil buffer.

This approach had a serious deficiency for mipmapped or multi-layer
textures. Any given moment the embedded stencil buffer was consistent with
exactly one miptree slice, the most recent one to be scattered. This
permitted tests of type A to pass, but broke tests of type B.

Test A:
    1. Create a depthstencil texture.

    3. Read and test stencil data at (level=x1, layer=y1).

This refactor does the following:
   - In intel_update_wrapper() and intel_wrap_texture(), change the
     parameters to prepare to remove functions' dependency on
     gl_texture_image.
   - Move the call to intel_renderbuffer_set_draw_offsets() from

(Update which wrapper? What is wrapped? What is the wrapper?). So, while
I was mucking around, I also renamed the functions.

It is simple to determine if a texture is a cube or not, so the presence

This patch removes 'nr_images' and assigns to 'depth' a consistent
meaning: depth is the number of 2D slices at each miplevel.  The exact
semantics of depth varies according to the texture target:
   - For GL_TEXTURE_CUBE_MAP, depth is 6.
   - For GL_TEXTURE_2D_ARRAY, depth is the number of array slices. It is
     identical for all miplevels in the texture.
   - For GL_TEXTURE_3D, it is the texture's depth at each miplevel. Its
     value, like width and height, varies with miplevel.
   - For other texture types, depth is 1.

As a consequence, parameters were removed from the following function
signatures:
    intel_miptree_set_level_info
        Remove 'nr_images'.

    i945_miptree_layout

intel: Fix swrast_render_start() for depthstencil buffers with separate stencil

1. Don't map the depthstencil buffer twice

   Place a guard in intel_renderbuffer_map() to prevent a renderbuffer
   from being mapped twice. This happened if a single buffer was attached to
   the framebuffer's depth and stencil attachment points.  (Interestingly,
   because intel_map_renderbuffer_gtt() is idempotent, the double mapping did
   not cause bugs for depthstencil buffers *without* separate stencil).

2. Stop overriding gl_framebuffer::_DepthBuffer,_StencilBuffer

   Normally, if a depthstencil buffer is attached to the framebuffer's
   depth attachment point, then _mesa_update_framebuffer() installs
   a wrapper depth renderbuffer at gl_framebuffer::_DepthBuffer. Ditto for
   the stencil attachment point and gl_framebuffer::_StencilBuffer

   A depthstencil intel_renderbuffer with separate stencil contains hidden
   depth and stencil renderbuffers, which are the *real* renderbuffers. In
   order to force swrast to work, we were installing, in
   brw_update_draw_buffer(), the hidden renderbuffers at
   gl_framebuffer::_DepthBuffer and _StencilBuffer, thus overriding the
   behavior of _mesa_update_framebuffer().  However, now that
   intel_renderbuffer_map() is implemented with MapRenderbuffer(),
   overriding _mesa_update_framebuffer's introduces bugs.  This patch
   removes the override code.

Fixes several Piglit tests on gen7.

glsl: Always search for an exact function signature match.

Previously, we would fail to compile the following shader due to a bug
in lazy built-in importing:

    #version 130
    void main() {
        float f = abs(5.0);
        int i = abs(5);
    }

The first call, abs(5.0), would fail to find a local signature, look
through the built-ins, and import "float abs(float)".

The second call, abs(5), would find the newly imported float signature
in the local shader, and settle for that.  Unfortunately, it failed to
search the built-ins for the correct/exact signature, "int abs(int)".

Thus, abs(5) ended up being a float, causing a bizarre type error when
we tried to assign it to an int.

Fixes piglit test builtin-overload-matching.frag.

This is /not/ a candidate for stable branches, as it should only be
possible to trigger this bug using GLSL 1.30's built-in functions that
take integer arguments.  Plus, the changes are fairly invasive.

glsl: Split code to generate an ir_call out from match_function_by_name.

match_function_by_name performs two fairly separate tasks:
1. Hunt down the appropriate ir_function_signature for the callee.
2. Generate the actual ir_call (assuming we found the callee).

Both of these are complicated.  The first has to handle exact/inexact
matches, lazy importing of built-in prototypes, different scoping rules
for 1.10, 1.20+, and ES.  Not to mention printing a user-friendly error
message with pretty-printed "maybe you meant this" candidate signatures.

The second has to deal with void/non-void functions, pre-call implicit
conversions for "in" parmeters, and post-call "out" call conversions.

Trying to do both in one function is just too unwieldy.  Time to split.

This patch purely moves the code to generate an ir_call into a separate

12 years agoglsl: Add a new matching_signature() variant that returns exact/inexact.

glsl: Add a new matching_signature() variant that returns exact/inexact.

When matching function signatures across multiple linked shaders, we
often want to see if the current shader has _any_ match, but also know
whether or not it was exact.  (If not, we may want to keep looking.)

This could be done via the existing mechanisms:

   sig = f->exact_matching_signature(params);
   if (sig != NULL) {
      exact = true;
   } else {
      sig = f->matching_signature(params);
      exact = false;
   }

However, this requires walking the list of function signatures twice,
which also means walking each signature's formal parameter lists twice.
This could be rather expensive.

Since matching_signature already internally knows whether a match was
exact or not, we can just return it to get that information for free.

r600g: fix the representation of control-flow instructions

We need something that looks like a compiler and not like some hacker
put some functions together. /rant

This is a band-aid for these two problems:
- The R600 and EG control-flow instructions appear in switch statements
  next to each other, causing conflicts when adding new instructions.
- The ALU control-flow instructions are bitshifted by 3 (from CF_INST 26:29
  to CF_INST 23:29, as is defined by r600 ISA) even for EG, where CF_INST
  is 22:29.

To fix this mess, the 'inst' field is bitshifted to the left either by 22, 23,
or 26 (directly in the definitions), such that it can be just or'd when making
bytecode without any shifting. All switch statements have been divided into
two, one for R600 and the other for EG.

Of course, there is a better way to do this, but that is left for future
work.

Tested on RV730 and REDWOOD with no regressions.

v2: minor cleanup as per Alex's comment.
