* glsl: Parse and propagate derivative_group to shader_infoCaio Marcelo de Oliveira Filho2019-04-081-0/+11
| | | | | | | | | | | | NV_compute_shader_derivatives allow selecting between two possible arrangements (quads and linear) when calculating derivatives and certain subgroup operations in case of Vulkan. So parse and propagate those up to shader_info.h. v2: Do not fail when ARB_compute_variable_group_size is being used, since we are still clarifying what is the right thing to do here.

* glsl: Add pragma to disable all warningsIan Romanick2018-11-081-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | Use #pragma warning(off) and #pragma warning(on) to disable or enable all warnings. This is a big hammer. If we ever need a smaller hammer, we can enhance this functionality. There is one lame thing about this. Because we parse everything, create an AST, then convert the AST to GLSL IR, we have to treat the #pragma like a statment. This means that you can't do something like ' void ' #pragma warning(off) ' __foo ' #pragma warning(on) ' (float param0); Fixing that would, as far as I can tell, require a huge amount of work. I did try just handling the #pragma during parsing (like we do for state for the whole shader. v2: Fix the #pragma lines in the commit message that git-commit ate.

| | | | | | | | | | | | | This extension provides new GLSL built-in functions beginInvocationInterlockARB() and endInvocationInterlockARB() that delimit a critical section of fragment shader code. For pairs of shader invocations with "overlapping" coverage in a given pixel, the OpenGL implementation will guarantee that the critical section of the fragment shader will be executed for only one fragment at a time.

* glsl: Switch ast_type_qualifier to a 128-bit bitset.Francisco Jerez2018-02-241-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | 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).

The commit was erroneous because the ast_layout_expression class was created to hold a list of values for a layout-qualifier-name which is allowed to appear in more than one expression in the same shader/program but not to hold different values. In other words, the list is used for an after check that all the declared values for a layout-qualifier-name are consistent. Therefore, the values stored must match always, not just for "max_vertices" or any other eventual layout-qualifier-name.

| | | | | | | | | | | | | | | | | | | | | | After the previous modifications in the merging of the layout-qualifier-name values, we no longer push the final value in a declaration to the global values. This regression happens because we don't call for merging on the right-most layout qualifier of a declaration which is also the overriding one in case of multiple appearances. Now, we add a new method to push these values to the global ones and we call for this just after all the layout-qualifier collapsing has happened in a declaration. This simplifies how this was working in two ways; we make a clear differentiation of when we are pushing this to the global values since before it was mixed in the merging call and we only run this once all the processing for layout-qualifiers in a declaration has happened.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | layout qualifier From page 46 (page 52 of the PDF) of the GLSL 4.20 spec: " More than one layout qualifier may appear in a single declaration. If the same layout-qualifier-name occurs in multiple layout qualifiers for the same declaration, the last one overrides the former ones." Consider this example: " #version 150 #extension GL_ARB_shading_language_420pack: enable layout(max_vertices=2) layout(max_vertices=3) out; layout(max_vertices=3) out;" Although different values for "max_vertices" results in a compilation error. The above code is valid because max_vertices=2 is ignored. Hence, when merging qualifiers in an ast_type_qualifier, we now ignore new appearances of a same layout-qualifier-name if the new "is_multiple_layouts_merge" parameter is on, since the GLSL parser works in this case from right to left. In addition, any special treatment for the buffer, uniform, in or out layout defaults has been moved in the GLSL parser to the rule triggered just after any previous processing/merging on the layout-qualifiers has happened in a single declaration since it was run too soon previously.

Our ast_type_qualifier merges with others in a way that if the value for a layout-qualifier-id is set in both, the object being merged overwrites the value of the object invoking the merge. Hence, the merge has to happen from the left layout towards the right one and this was not happening for interface blocks because we were merging into the default layout qualifier. Now, the merge is done from left to right and, as a last step, we merge into the default layout qualifier if needed, so the values of the explicit layouts prevail over it.
