This also means that the code generator for future hardware won't have

11 years agoi965/fs: Split final assembly code generation out of fs_visitor.
Kenneth Graunke [Fri, 9 Nov 2012 09:05:47 +0000 (01:05 -0800)]
i965/fs: Split final assembly code generation out of fs_visitor.

Compiling shaders requires several main steps:

   1. Generating FS IR from either GLSL IR or Mesa IR
   2. Optimizing the IR
   3. Register allocation
   4. Generating assembly code

This patch splits out step 4 into a separate class named "fs_generator."

There are several reasons for doing so:

   1. Future hardware has a different instruction encoding.  Splitting
      this out will allow us to replace fs_generator (which relies
      heavily on the brw_eu_emit.c code and struct brw_instruction) with
      a new code generator that writes the new format.

   2. It reduces the size of the fs_visitor monolith.  (Arguably, a lot
      more should be split out, but that's left for "future work.")

   3. Separate namespaces allow us to make helper functions for
      generating instructions in both classes: ADD() can exist in
      fs_visitor and create IR, while ADD() in fs_generator() can
      create brw_instructions.  (Patches for this upcoming.)

Furthermore, this patch changes the order of operations slightly.
Rather than doing steps 1-4 for SIMD8, then 1-4 for SIMD16, we now:

   - Do steps 1-3 for SIMD8, then repeat 1-3 for SIMD16
   - Generate final assembly code for both modes together

This is because the frontend work can be done independently, but final
assembly generation needs to pack both into a single program store to
feed the GPU.

mesa/vbo: Fix scaling issue in 2-bit signed normalized packing.

Since a signed 2-bit integer can only represent -1, 0, or 1, it is
tempting to simply to convert it directly to a float.  This maps it
onto the correct range of [-1.0, 1.0].  However, it gives different
values compared to the usual equation:

(2.0 *  1.0 + 1.0) * (1.0 / 3.0) = +1.0           (same)
(2.0 *  0.0 + 1.0) * (1.0 / 3.0) = +0.33333333... (different)
(2.0 * -1.0 + 1.0) * (1.0 / 3.0) = -0.33333333... (different)

According to the GL_ARB_vertex_type_2_10_10_10_rev extension, signed
normalization is performed using equation 2.2 from the GL 3.2
specification, which is:

   f = (2c + 1)/(2^b - 1).                                (2.2)

Comments below that equation state: "In general, this representation is
used for signed normalized fixed-point parameters in GL commands, such
as vertex attribute values."  Which is what we're doing here.

The 3.2 specification goes on to declare an alternate formula:

   f = max{c/(2^(b-1) - 1), -1.0}                         (2.3)

which is closer to the existing code, and maps the end points to exactly
-1.0 and 1.0.  Comments below the equation state: "In general, this
representation is used for signed normalized fixed-point texture or
framebuffer values."  Which is *not* what we're doing here.

It then states: "Everywhere that signed normalized fixed-point
values are converted, the equation used is specified."  This is the real
clincher: the extension explicitly specifies that we must use equation
2.2, not 2.3.  So we need to do (2x + 1) / 3.

This matches the behavior expected by oglconform's packed-vertex test,
and is correct for desktop GL (pre-4.2).  It's not correct for ES 3.0,
but a future patch will correct that.

mesa/vbo: Fix scaling issue in 10-bit signed normalized packing.

For the 10-bit components, the divisor was incorrect.  A 10-bit signed
integer can represent -2^9 through 2^9 - 1, which leads to the following
ranges:

       (float)value.x          -> [ -512,  511]
2.0F * (float)value.x          -> [-1024, 1022]
2.0F * (float)value.x + 1.0F   -> [-1023, 1023]

So dividing by 511 would incorrectly scale it to approximately:
[-2.001956947, 2.001956947].  To correctly scale to [-1.0, 1.0], we need
to divide by 1023.

This correctly implements the desktop GL rules.  ES 3.0 has different
rules, but those will be implemented in a separate patch.

get clipped by the drawable's bounds.  But if a smaller-than-window-size
