12 years agomesa: fix the selection of soft renderbuffer color formats

mesa: fix the selection of soft renderbuffer color formats

This fixes a regression from the recent glReadPixels changes found
with the piglit hiz tests.

Use either MESA_FORMAT_RGBA8888 or MESA_FORMAT_RGBA8888_REV for color
buffers depending on endian-ness.  Before, the gl_renderbuffer::Format
field was MESA_FORMAT_RGBA8888 but the data was really stored as
MESA_FORMAT_RGBA8888_REV when using a little endian machine.

Getting this right matters now that we can access renderbuffer data
without going through the span functions (namely glReadPixels() +
MapRenderbuffer()).

The documentation claims that SIMD16 mode isn't supported for INT DIV,

is trying to warn us that the variant that returns both quotient and
remainder in (dst, dst + 1) doesn't work in SIMD16 mode since dst + 1
would be sechalf(dst), trashing half your results.  Since we don't use
that variant, we don't care and can just enable SIMD16 everywhere.

conditional modifiers aren't supported, but empirical evidence and

 * For non-const variables, a field to track the constant value of the

For variables non-constant initalizers, ir_variable::has_initializer
will be true, but ir_variable::constant_initializer will be NULL.  The
linker can use the values of these fields to check adherence to the
GLSL 4.20 rules for shared global variables:

    "If a shared global has multiple initializers, the initializers
    must all be constant expressions, and they must all have the same
    value. Otherwise, a link error will result. (A shared global
    having only one initializer does not require that initializer to
    be a constant expression.)"

Previous to 4.20 the GLSL spec simply said that initializers must have
the same value.  In this case of non-constant initializers, this was
