11 years agoxlib: use _mesa_generate_mipmap() for mipmap generation, not meta

xlib: use _mesa_generate_mipmap() for mipmap generation, not meta

The swrast fragment program interpreter has trouble computing the
right texture LOD because it doesn't have easy access to input
derivatives.  This causes the GLSL-based meta generate mipmap code
to fetch texels from the wrong mipmap level.

One possible fix would be to set the GL_TEXTURE_MIN/MAX_LOD parameters
to limit sampling from the right level.  But let's just use the
_mesa_generate_mipmap() fallback since it's a lot faster than using
the fragment shader interpreter.

calls to u_upload_data()) to detect OOM errors.

glsl: Add a predicate to determine whether a variable is an interface block

For the first declaration below, there will be an ir_variable named
"instance" whose type and whose instance_type will be the same
glsl_type.  For the second declaration, there will be an ir_variable
named "f" whose type is float and whose instance_type is B2.

"instance" is an interface instance variable, but "f" is not.

uniform B1 {
    float f;
} instance;

uniform B2 {
    float f;
};

v2: Copy the comment message documentation into the code.  Suggested by
Paul Berry.

glsl: Add GLSL_TYPE_INTERFACE

Interfaces are structurally identical to structures from the compiler's
point of view.  They have some additional restrictions, and generally
GPUs use different instructions to access them.  Using a different base
type should make this a bit easier.

This commit also adds the glsl_type::interface_packing fields.  For
GLSL_TYPE_INTERFACE types, this will track the specified packing mode.
It is analogous to gl_uniform_buffer::_Packing.

v2: Add serveral missing GLSL_TYPE_INTERFACE cases in switch-statements.

v3: Add information about glsl_type::interface_packing.  Move row_major
checking in glsl_type::record_key_compare from this patch to the
previous patch.  Both suggested by Paul Berry.
