behavior, preventing us from using prog_to_nir.

According to llvm/lib/Target/AMDGPU/SIInstructions.td, POW_common
expands to <V_LOG_F32_e32, V_EXP_F32_e32, V_MUL_LEGACY_F32_e32>,
which presumably does a zero-wins multiply.

Lowering in NIR results in a non-legacy multiply, where:

   pow(0, 0) = 2^(log2(0) * 0)
             = 2^(-INF * 0)
             = 2^(-NaN)
             = -NaN

Kenneth Graunke [Wed, 16 Jan 2019 06:35:02 +0000 (22:35 -0800)]
mesa: Align doubles to a 64-bit starting boundary, even if packing.

In the new Intel Iris driver, I am using Tim's new packed uniform
storage system.  It works great, with one caveat: our scalar compiler
backend assumes that uniform offsets will be aligned to the underlying
data type.  For example, doubles must be 64-bit aligned, floats 32-bit,
half-floats 16-bit, and so on.  It does not need any other padding.

Currently, _mesa_add_parameter aligns everything to 32-bit offsets,
creating doubles that have an unaligned offset.  This patch alters
that code to align doubles to 64-bit offsets.

This may be slightly less optimal for drivers which can support full
packing, and allow reads from unaligned offsets at no penalty.  We could
make this extra alignment optional.  However, it only comes into play
when intermixing double and single precision uniforms.  Doubles are
already not too common, and intermixed values (floats then doubles)
is probably even less common.  At most, we burn a single 32-bit slot
to the alignment, which is not that expensive.  So, it doesn't seem
worthwhile to add the extra complexity.

Eventually, we'll likely want to update this code to allow half-float
values to be packed tighter than 32-bit offsets.  At that point, we'll
probably want to revisit what drivers ultimately want, and add options.

You were allowed to pass in any old temp so that you could hopefully fold
the PF up into the def of the temp.  If we couldn't find one, it

different behavior depending on whether the def being folded into was a
float or int opcode, which the caller doesn't necessarily control.

Due to the fragility of the function, just switch all callers over to
vir_set_pf().  This also encourages the callers to use a _dest call for
the inst they're putting the PF on, eliminating a bunch of temps in the

Eleni Maria Stea [Fri, 15 Feb 2019 13:29:41 +0000 (15:29 +0200)]
i965: Faking the ETC2 compression on Gen < 8 GPUs using two miptrees.

GPUs Gen < 8 cannot sample ETC2 formats. So far, they converted the
compressed EAC/ETC2 images to non-compressed RGBA images. When
GetCompressed* functions were called, the pixels were returned in this
RGBA format and not the compressed format that was expected.

Trying to fix this problem, we use a secondary shadow miptree to store the
decompressed data for the rendering and the main miptree to store the
compressed for the Get functions to work. Each time that the main miptree
is written with compressed data, we decompress them to RGB and update the
shadow. Then we use the shadow for rendering.

v2:
   - Fixes in the commit message (Nanley Chery)
   - Reversed the changes in brw_get_texture_swizzle and swapped the b, g
   values at the time that we decompress the data in the function:
   intel_miptree_update_etc_shadow of intel_mipmap_tree.c (Nanley Chery)
   - Simplified the format checks in the miptree_create function of the
   intel_mipmap_tree.c and reserved the call of the
   intel_lower_compressed_format for the case that we are faking the ETC
   support (Nanley Chery)
   - Removed the check for the auxiliary usage for the shadow miptree at
   creation (miptree_create of intel_mipmap_tree.c) as we won't use
   auxiliary buffers with these types of trees (Nanley Chery)
   - Set the etc_format of the non-ETC miptrees to MESA_FORMAT_NONE and

   mt->shadow_needs_update to true to catch all the cases when we need to
   update the miptree (Nanley Chery)
   - In order to update the shadow miptree during the unmap of the
   main and always map the main (Nanley Chery) the following change was
   necessary: Splitted the previous update function that was updating all
   the mipmap levels and use two functions instead: one that updates one
   level and one that updates all of them. Used the first during unmap
   and the second before the rendering.
   - Removed the BRW_MAP_ETC_BIT flag and the mechanism to decide which
   miptree should be mapped each time and reversed all the changes in the
   higher level texture functions that upload data to textures as they
   aren't needed anymore.
   - Replaced the boolean needs_fake_etc with an inline function that
   checks when we need to fake the ETC compression (Nanley Chery)
   - Removed the initialization of the strides in the update function as
   the values will be overwritten by the intel_miptree_map call (Nanley
   Chery)
   - Used minify instead of division in the new update function
   intel_miptree_update_etc_shadow_levels in intel_mipmap_tree.c (Nanley

   - Removed the depth from the calculation of the number of slices in
