I was thinking of the MIN opcode in terms of unsigned math, but it's
signed, so if you used a negative array index, you could read before the
UBO. Fixes segfaults under simulation in piglit array indexing tests with
mprotect-based guard pages.
I wanted to assert that src1 came from a non-unspilled register in shader
validation, and this easily gets us that. And, as a bonus:
total instructions in shared programs: 93347 -> 92723 (-0.67%)
instructions in affected programs: 60524 -> 59900 (-1.03%)
Disabling miptails fixed the buffer corruption happening in FBO
which use YF/YS tiled renderbuffer or texture as color attachment.
Spec recommends disabling mip tails only for non-mip-mapped surfaces.
But, without disabling miptails I couldn't get correct data out of
mipmapped YF/YS tiled surface.
We need better understanding of miptails before start using them.
For now this patch helps move things forward.

Previously when setting up the sample instruction for an indirect
sampler the vec4 backend was directly passing the pseudo opcode's
src0. However vec4_visitor::visit(ir_texture *) doesn't set the
texture operation's src0 -- it's left as BAD_FILE, which when
translated into a brw_reg gives the null register. In brw_SAMPLE,
gen6_resolve_implied_move() inserts a MOV from the inst->base_mrf and
sets the src0 appropriately. The indirect sampler case did not have a
call to gen6_resolve_implied_move().
The fs backend avoids this because the platforms that support dynamic
indexing of samplers (IVB+) have been converted to not use the
fake-MRF hack, and instead send from proper GRFs.
This patch makes it call gen6_resolve_implied_move before setting up
the indirect message. This is similar to what is done for constant
sampler numbers in brw_SAMPLE.
The Piglit tests for sampler array indexing didn't pick this up
because they were using a texture with a solid colour so it didn't
matter what texture coordinates were actually used. The tests have now
been changed to be more thorough in this commit:
http://cgit.freedesktop.org/piglit/commit/?id=4f9caf084eda7
With that patch the tests for gs and vs are currently failing on
Ivybridge, but this patch fixes them. There are no other changes to a
Piglit run on Ivybridge.
On Skylake the gs tests were failing even without the Piglit patch
because Skylake needs the source registers to work correctly in order
to send a message header to select SIMD4x2 mode.

and the size is not specified at compile-time, it is sized at run-time.

This function was trying to align the width and height to a multiple
of the block size for compressed textures. It was using align_w/h as a
shortcut to get the block size as up until Gen9 this always happens to
match. However in Gen9+ the alignment values are expressed as
multiples of the block size so in effect the alignment values are
always 4 for compressed textures as that is the minimum value we can
pick. This happened to work for most compressed formats because the
block size is also 4, but for FXT1 this was breaking because it has a
block width of 8.
This fixes some Piglit tests testing FXT1 such as

One of the places we have to insert texbars is in situations where the
result of the tex gets overwritten by a different instruction (e.g. in a
conditional statement). However in some situations it can actually
appear as though the original tex itself is an overwriting instruction.
This can naturally never really happen, so just ignore the tex
instruction when it comes up.

Back in 2013, a patch was added (with 2 reviewers!) at the end of the
block to early exit the loop in this case, without noticing that the loop
already did. I added another early exit case, again without noticing, but
Rob caught me. Just drop the loop condition that apparently surprises
most of us, instead of leaving the end of the loop conspicuously not
exiting on success.
