* nir/serialize: handle var->name being NULLAlejandro Piñeiro2018-03-011-1/+2
| | | | | | | | var->name could be NULL under ARB_gl_spirv for example. And in any case, the code is already handing var name being NULL when reading a variable, so it is consistent to do it writing a variable too. Reviewed-by: Timothy Arceri <[email protected]>
* spirv/i965/anv: Relax push constant offset assertions being 32-bit alignedJose Maria Casanova Crespo2018-02-281-2/+0
| | | | | | | | | | | | | | | | The introduction of 16-bit types with VK_KHR_16bit_storages implies that push constant offsets could be multiple of 2-bytes. Some assertions are updated so offsets should be just multiple of size of the base type but in some cases we can not assume it as doubles aren't aligned to 8 bytes in some cases. For 16-bit types, the push constant offset takes into account the internal offset in the 32-bit uniform bucket adding 2-bytes when we access not 32-bit aligned elements. In all 32-bit aligned cases it just becomes 0. v2: Assert offsets to be aligned to the dest type size. (Jason Ekstrand) Reviewed-by: Jason Ekstrand <[email protected]>

* glsl/linker: fix bug when checking precision qualifierSamuel Iglesias Gonsálvez2018-02-281-8/+3
| | | | | | | | | | | | | | | According to GLSL ES 3.2 spec, see table in 9.2.1 "Linked Shaders" section, the precision qualifier should match for uniform variables. This also applies to previous GLSL ES 3.x specs. This 'if' checks the condition for uniform variables, while for UBOs it is checked in link_interface_blocks.cpp. Fixes: b50b82b8a553 ("glsl/es31: precision qualifier doesn't need to match in shader interface block members") Signed-off-by: Samuel Iglesias Gonsálvez <[email protected]> Reviewed-by: Tapani Pälli <[email protected]>

* glsl: Specify framebuffer fetch coherency mode in ↵Francisco Jerez2018-02-242-2/+3
| | | | | | | | | | | | | | | | | | | | | lower_blend_equation_advanced(). This requires passing an extra argument to the lowering pass because the KHR_blend_equation_advanced specification doesn't seem to define any mechanism for the implementation to determine at compile-time whether coherent blending can ever be used (not even an "#extension KHR_blend_equation_advanced_coherent" directive seems to be required in the shader source AFAICT). In the long run we'll probably want to do state-dependent recompiles based on the value of ctx->Color.BlendCoherent, but right now there would be no benefit from that because the only driver that supports coherent framebuffer fetch is i965 on SKL+ hardware, which are unable to support the non-coherent path for the moment because of texture layout issues, so framebuffer fetch coherency is always enabled for them.

* glsl: Add support for the framebuffer fetch layout(noncoherent) qualifier.Francisco Jerez2018-02-245-2/+61
| | | | | | | | | | This allows the application to request framebuffer fetch coherency with per-fragment output granularity. Coherent framebuffer fetch outputs (which is the default if no qualifier is present for compatibility with older versions of the EXT_shader_framebuffer_fetch extension) will have ir_variable_data::memory_coherent set to true.

* glsl: Switch ast_type_qualifier to a 128-bit bitset.Francisco Jerez2018-02-243-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | This should end the drought of bits in the ast_type_qualifier object. The bitset_t type works pretty much as a drop-in replacement for the current uint64_t bitset. The only catch is that the bitset_t type as defined in the previous commit doesn't have a trivial constructor (because it has a user-defined constructor), so it cannot be used as union member without providing a user-defined constructor for the union (which causes it in turn to be non-trivially constructible). This annoyance could be easily addressed in C++11 by declaring the default constructor of bitset_t to be the implicitly defined one -- IMO one more reason to drop support for GCC 4.2-4.3. The other minor change was required because glsl_parser_extras.cpp was hard-coding the type of bitset temporaries as uint64_t, which (unlike would have been the case if the uint64_t had been replaced with e.g. an __int128) would otherwise have caused a build failure, because the boolean conversion operator of bitset_t is marked explicit (if C++11 is available), so the bitset won't be silently truncated down to 1 bit in order to use it to initialize the uint64_t temporaries (yikes).

| | | | | | | | | | | | | | | | | | c2acf97fcc9b32e changed the use of double_inputs_read to be inconsitent with its previous meaning. Here we re-enable the gather info code that was removed as the modified code from c2acf97fcc9b32e now uses the double_inputs member rather than double_inputs_read. This change allows us to use double_inputs_read with gallium drivers without impacting double_inputs which is used by i965. We also make use of the compiler option vs_inputs_dual_locations to allow for the difference in behaviour between drivers that handle vs inputs as taking up two locations for doubles, versus those that treat them as taking a single location.
