possible approaches to this problem:

 1) Emit the code to calculate the subgroup invocation on-the-fly and
    trust NIR to do the CSE.  This is what we were doing.

 2) Add a back-end instruction for the subgroup ID.  This has the
    advantage of helping the back-end compiler with CSE but has the
    downside of very poor scheduling for the calculation because it has
    to be emitted in the back-end.

 3) Emit the calculation at the top of the program and re-use the
    result.  This gets rid of the CSE problem but comes at the cost of
    an extra live register.

This commit switches us from 1) to 3).  We choose to store the subgroup
invocation values as a W type to reduce the impact of the extra live
register.  Trusting NIR and using 1) was fine but we're soon going to
want to use the subgroup invocation value for other things in the

6 years agoglsl: Allow precision mismatch on dead data with GLSL ES 1.00
Tomasz Figa [Tue, 26 Sep 2017 08:35:56 +0000 (17:35 +0900)]
glsl: Allow precision mismatch on dead data with GLSL ES 1.00

Commit 259fc505454ea6a67aeacf6cdebf1398d9947759 added linker error for
mismatching uniform precision, as required by GLES 3.0 specification and
conformance test-suite.

Several Android applications, including Forge of Empires, have shaders
which violate this rule, on a dead varying that will be eliminated.
The problem affects a big number of applications using Cocos2D engine
and other GLES implementations accept this, this poses a serious
application compatibility issue.

Starting from GLSL ES 3.0, declarations with conflicting precision
qualifiers are explicitly prohibited. However GLSL ES 1.00 does not
clearly specify the behavior, except that

  "Uniforms are defined to behave as if they are using the same storage in
  the vertex and fragment processors and may be implemented this way.
  If uniforms are used in both the vertex and fragment shaders, developers
  should be warned if the precisions are different. Conversion of
  precision should never be implicit."

The word "used" is not clear in this context and might refer to
 1) declared (same as GLES 3.x)
 2) referred after post-processing, or
 3) linked after all optimizations are done.

Looking at existing applications, 2) or 3) seems to be widely adopted.
To avoid compatibility issues, turn the error into a warning if GLSL ES
version is lower than 3.0 and the data is dead in at least one of the
shaders.
