This prepares for selectively enabling hiz on individual miptree slices

This refactoring had several side effects.

  1. To prevent new warnings about discarding the const qualifier,
     I removed 'const' from some variable declarations in
     intel_validate_framebuffer().  The alternative was to add const
     qualifiers to multiple function signatures in the
     intel_renderbuffer_has_hiz call graph. Since the dominant convention
     in the Intel code is to not qualify function parameters as const,
     I chose to remove rather than add const qualifiers.

  2. I changed the signature of brw_emit_depth_stencil_hiz() by replacing
     `struct intel_mipmap_tree *hiz_mt` with `bool hiz`. The function used

Commit dfb57e7 (glsl: Fix error checking on "flat" keyword to match
GLSL ES 3.00, GLSL 1.50) relaxed the rules for integral varyings: they
only need to be declared as "flat" if they are a fragment shader
inputs.  This allowed for the possibility of a vertex shader output
being a non-flat integer, provided that it was not matched to a
fragment shader input.  A non-contrived situation where this might
arise is if a vertex shader generates some integral outputs which are
consumed by tranform feedback, but not by the fragment shader.

Unfortunately, lower_packed_varyings assumes that *all* integral
varyings are flat, regardless of whether they are consumed by the
fragment shader.  As a result, attempting to create a non-flat
integral vertex output of a size that required packing (i.e. a size
other than ivec4 or uvec4) would cause an assertion failure in
lower_packed_varyings.

This patch prevents the assertion failure by forcing vertex shader
outputs to be "flat" whenever they are not consumed by the fragment
shader.  This should have no effect on rendering since the "flat"
keyword only affects the behaviour of fragment shader inputs.

11 years agoglsl: Remove some unnecessary uses of error_emitted
Ian Romanick [Fri, 15 Mar 2013 21:27:22 +0000 (14:27 -0700)]
glsl: Remove some unnecessary uses of error_emitted

The error_emitted flag is used in semantic checking to prevent spurious
cascading errors.  For example,

void foo(sampler2D s, float a)
{
    float x = a + (1.2 + s);

    ...
}

should only generate a single error.  Without the error_emitted flag for
the first error, "a + ..." would also generate an error.

However, a bunch of cases in _mesa_ast_array_index_to_hir that were
setting error_emitted would mask legitimate errors.  For example,

    vec4 a[7];
    float b = a[3.14];

should generate two error (float index and type mismatch in assignment).
The uses of error_emitted would cause only the first to be emitted.

This patch removes most of the places in _mesa_ast_array_index_to_hir
that would set the error_emitted flag.
