4 years agoac/nir: export some undef as zero
Pierre-Eric Pelloux-Prayer [Tue, 28 Apr 2020 14:34:49 +0000 (16:34 +0200)]
ac/nir: export some undef as zero

NIR already optimizes undef usage.
If undef reaches llvm, it's probably because of a broken shader.

In this situation, rather than letting llvm use the undef values
to do more optimization and probably produce incorrect results,
we replace undef values by 0.

"undef" values that are directly used in exports are kept as undef,
because this allows llvm to optimize them away.

This is only enabled for radeonsi.

mesa: extend GLSLZeroInit semantics

This commit introduces a new way to zero-init variables but keep the
old one to not break any existing behavior.

With this change GLSLZeroInit becomes an integer, with the following
possible values:
 - 0: no 0 init
 - 1: current behavior
 - 2: new behavior. Similar to 1, except ir_var_function_out type are
      0 initialized but ir_var_shader_out.

The rationale behind 2 is: zero initializing ir_var_shader_out can
prevent some optimization where out variables are completely eliminated
when not written to.

On the other hand, zero initializing "ir_var_function_out" has no
effect on correct shaders but typically helps shadertoy since the main
function is:

   void mainImage(out vec4 fragColor) { ... }

So with this change we're sure that fragColor will always get a value.

4 years agoradv: enable shaderInt16 unconditionally with LLVM and only GFX8+ with ACO
Samuel Pitoiset [Mon, 4 May 2020 10:01:41 +0000 (12:01 +0200)]
radv: enable shaderInt16 unconditionally with LLVM and only GFX8+ with ACO

The Vulkan spec says:

"shaderInt16 specifies whether 16-bit integers (signed and unsigned)
are supported in shader code. If this feature is not enabled, 16-bit
integer types must not be used in shader code."

I think it's just safe to enable it because 16-bit integers should
be fully supported with LLVM and also with ACO and GFX8+. On GFX8
and earlier generations, throughput of 16-bit int is same as 32-bit
but that should't change anything.

For GFX6-GFX7 ACO support, we have to implement conversions without
SDWA.
