* glsl: use separate varying slots for patch varyingsMarek Olšák2015-07-234-12/+49
| | | | | | | The idea is to allow 32 normal varyings and 32 patch varyings, a total of 64. Previously, only a total of 32 was allowed. Reviewed-by: Kenneth Graunke <[email protected]>

* glsl: validate restrictions on use of barrier()Chris Forbes2015-07-231-0/+99
| | | | | | | | | | With the exception of always-taken switch cases (which are indistinguishable from straight line code in our IR), this disallows use of the builtin barrier() function in all the places it may not appear.

* glsl: pass shader stage to lower_output_reads and handle tess controlIlia Mirkin2015-07-234-7/+12
| | | | | | | | | | | | | Tessellation control outputs can be read in directly without first having been written. Accessing these will require some special logic anyways, so just let them through. V2: Never lower tess control output reads, whether patch or not -- both can be read back by other threads.

* glsl: add the tessellation extension to the list for the "layout" qualifierMarek Olšák2015-07-231-1/+2
| | | | | | | | | | | | | | | | This is technically not needed, but it makes the compiler return a better error message if tessellation is used with GLSL < 1.50. Instead of: error: syntax error, unexpected NEW_IDENTIFIER, expecting $end It returns: error: #version 150 layout qualifier `triangles' used And the tessellation spec says: OpenGL 3.2 and GLSL 1.50 are required. So it makes perfect sense. Reviewed-by: Kenneth Graunke <[email protected]>
* glsl: don't lower variable indexing on non-patch tessellation inputs/outputsMarek Olšák2015-07-236-21/+57
| | | | | | | | | | | | There is no way to lower them, because the array sizes are unknown at compile time. Based on a patch from: Fabian Bieler <[email protected]> v2: add comments Reviewed-by: Kenneth Graunke <[email protected]> Reviewed-by: Dave Airlie <[email protected]>
