glx/windows: Fix compilation with -Werror-format

Fix compilation where the DWORD type is used with a format, after
-Werror-format added by c9c1e261.

Some Win32 API types are different fundamental types in the 32-bit and
64-bit versions. This problem is then further compounded by the fact
that whilst both 32-bit Cygwin and 32-bit MinGW use the ILP32 data
model, 64-bit MinGW uses the LLP64 data model, but 64-bit Cygwin uses
the LP64 data model. This makes it near impossible to write printf
format specifiers which are correct for all those targets.

In the Win32 API, DWORD is an unsigned, 32-bit type.  So, it is defined
in terms of an unsigned long, except in the LP64 data model used by
64-bit Cygwin, where it is an unsigned int.

It should always be safe to cast it to unsigned int and use %u or %x.

isl: Mark enum isl_channel_select packed so it becomes 1 byte.

I recently discovered that the following code lead to valgrind errors:

   struct isl_swizzle swizzle = ISL_SWIZZLE_IDENTITY;
   VALGRIND_CHECK_MEM_IS_DEFINED(&swizzle, sizeof(swizzle));

which is surprising, because struct isl_swizzle is simply:

   struct isl_swizzle {
      enum isl_channel_select r:4;
      enum isl_channel_select g:4;
      enum isl_channel_select b:4;
      enum isl_channel_select a:4;
   };

and the above code initializes all of them with a C99 initializer.
Iván Briano reminded me that C99 initializers don't necessarily zero
padding.  A quick inspection revealed that sizeof(struct isl_swizzle)
was 4 (rather than the expected 2).  Ian Romanick suggested changing
it to uint16_t, since this is essentially dicing up an unsigned, and
that worked.

This patch marks enum isl_channel_select packed, changing its size
from 4 bytes to 1 byte.  This then makes struct isl_swizzle 2 bytes,
with no bogus padding fields.  This eliminates valgrind undefined
memory warnings.

These isl_swizzle values become part of our BLORP blit program keys,
which are then hashed.  This undefined padding was being included in
the hashing, possibly leading to issues.  I originally saw this error
when running KHR-GL45.texture_size_promotion.functional in iris under
valgrind.

The GBM code in platform_drm.c code passed in dri2_surf->gbm_surf as the

non-NULL, and if so, presumed that the caller is the DRM platform and
we should use the dri2_surf->gbm_surf pointer.

This worked for most platforms, which calloc their dri2_surf structure,
zeroing the data.  Unfortunately, platform_x11.c used malloc, leaving
most of the dri2_surf as garbage.  In particular, dri2_surf->gbm_surf
was often non-NULL, causing dri2_create_drawable to try and use it,
passing a garbage pointer to the createNewDrawable hook, usually leading
to a SIGBUS or SIGSEGV when trying to dereference that bad pointer.

winsys/svga/drm: Fix 32-bit RPCI send message

Depending on whether compiled with frame-pointer or not, the temporary
memory location used for the bp parameter in these macros are referenced
relative to the stack pointer or the frame pointer.
Hence we can never reference that parameter when we've modified either
the stack pointer or the frame pointer, because then the compiler would
generate an incorrect stack reference.

Fix this by pushing the temporary memory parameter on a known location on
the stack before modifying the stack- and frame pointers.

Also in case of failuire RPCI channel is not closed which lead to vmx

intel/fs: Improve discard_if code generation

Previously we would blindly emit an sequence like:

        mov(1)          f0.1<1>UW       g1.14<0,1,0>UW
        ...
        cmp.l.f0(16)    g7<1>F          g5<8,8,1>F      0x41700000F  /* 15F */
(+f0.1) cmp.z.f0.1(16)  null<1>D        g7<8,8,1>D      0D

The first move sets the flags based on the initial execution mask.
Later discard sequences contain a predicated compare that can only
remove more SIMD channels.  Often times the only user of the result from
the first compare is the second compare.  Instead, generate a sequence
like

        mov(1)          f0.1<1>UW       g1.14<0,1,0>UW
        ...
        cmp.l.f0(16)    g7<1>F          g5<8,8,1>F      0x41700000F  /* 15F */
(+f0.1) cmp.ge.f0.1(8)  null<1>F        g5<8,8,1>F      0x41700000F  /* 15F */

If the results stored in g7 and f0.0 are not used, the comparison will

Ian Romanick [Wed, 22 May 2019 17:18:06 +0000 (10:18 -0700)]
intel/fs: Fix flag_subreg handling in cmod propagation

There were two errors.  First, the pass could propagate conditional
modifiers from an instruction that writes on flag register to an
instruction that writes a different flag register.  For example,

    cmp.nz.f0.0(16) null:F, vgrf6:F, vgrf5:F
    cmp.nz.f0.1(16) null:F, vgrf6:F, vgrf5:F

could be come

    cmp.nz.f0.0(16) null:F, vgrf6:F, vgrf5:F

Second, if an instruction writes f0.1 has it's condition propagated, the
modified instruction will incorrectly write flag f0.0.  For example,

    linterp(16) vgrf6:F, g2:F, attr0:F
    cmp.z.f0.1(16) null:F, vgrf6:F, vgrf5:F
    (-f0.1) discard_jump(16) (null):UD

could become

    linterp.z.f0.0(16) vgrf6:F, g2:F, attr0:F
    (-f0.1) discard_jump(16) (null):UD

None of these cases will occur currently.  The only time we use f0.1 is
for generating discard intrinsics.  In all those cases, we generate a
squence like:

    cmp.nz.f0.0(16) vgrf7:F, vgrf6:F, vgrf5:F
    (+f0.1) cmp.z(16) null:D, vgrf7:D, 0d
    (-f0.1) discard_jump(16) (null):UD

Due to the mixed types and incompatible conditions, this sequence would
never see any cmod propagation.  The next patch will change this.

No shader-db changes on any Intel platform.

intel/blorp: Handle SINT/UINT clamping on blits.

This patch makes blorp_blit handle SINT<->UINT blit value clamping.
After reading the source's integer data (which is expanded to 32-bit),
we either IMAX with 0 (for SINT -> UINT, to clamp negative numbers) or
UMIN with (1 << 31) - 1 (for UINT -> SINT, to clamp positive numbers
outside of the representable range).

Such blits are not allowed by the OpenGL or Vulkan APIs directly:

   The Vulkan 1.1 spec for vkCmdBlitImage says:

   "Integer formats can only be converted to other integer formats with
    the same signedness."

   The GL 4.5 spec for glBlitFramebuffer says:

   "An INVALID_OPERATION error is generated if format conversions are
    not supported, which occurs under any of the following conditions:
    [...]
    * The read buffer contains unsigned integer values and any draw
      buffer does not contain unsigned integer values.
    * The read buffer contains signed integer values and any draw buffer
      does not contain signed integer values."

However, they are useful for other operations, such as texture upload
and download, which typically are implemented via blorp_blit().  i965
has code to fall back in this case (which the next commit will delete),
and Gallium expects blit() to handle this case for texture upload.

Fixes the following tests on iris:

works well...assuming nir_lower_double_ops actually gets an fmod op to

We currently have two duplicate mechanisms for lowering fmod@64.
One is a nir_opt_algebraic rule keyed off of options->lower_fmod64,
and the other is nir_lower_doubles, which offers a full gamut of
fp64 lowering.  The latter works slightly better in some corner cases,
so I'm trying to eliminate lower_fmod64 and drop the redundancy.
