* nir: add support for 64-bit in SmoothStep functionJuan A. Suarez Romero2017-06-271-3/+5
| | | | | | | | | | | According to GLSL.std.450 spec, SmoothStep expects input to be a floating-point type, but it does not restrict the bitsize. Current implementation relies on inputs to be 32-bit. This commit extends the support to 64-bit size inputs. Reviewed by: Elie Tournier <[email protected]>

* spirv: Work around the Doom shader bugJason Ekstrand2017-06-202-0/+28
| | | | | | | | | | | | | | | | | Doom shipped with a broken version of GLSLang which handles samplers as function arguments in a way that isn't spec-compliant. In particular, it creates a temporary local sampler variable and copies the sampler into it. While Dave has had a hack patch out for a while that gets it working, we've never landed it because we've been hoping that a game update would come out with fixed shaders. Unfortunately, no game update appears on to be on the horizon and I've found this issue in yet another application so I think we're stuck working around it. Hopefully, we can delete this code one day.

| | | | | | | | | | | | | Unnamed struct types are now equal across stages based on the fields they contain, so overriding the type to make sure names match has become unnecessary.

* glsl: stop considering unnamed and named structures equalNicolai Hähnle2017-06-131-6/+2
| | | | | | | | | | | | Previously, if an unnamed and a named struct contained the same fields, they were considered the same type during linking of globals. The discussion around commit e018ea81bf58 ("glsl: Structures must have same name to be considered same type.") doesn't seem to have considered this thoroughly, and I see no evidence that an unnamed struct should ever be considered to be the same type as a named struct.

* glsl: give all unnamed structs the same nameNicolai Hähnle2017-06-131-9/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As a result, unnamed structs defined in different places of the program are considered the same types if they have the same fields in the same order. This will simplify matching of global variables whose type is an unnamed struct. It also fixes a memory leak when the same shader containing unnamed structs is compiled over and over again: instead of creating a new type each time, the existing type is re-used. Finally, this does have the effect that some previously rejected programs are now accepted, such as: struct { float a; } s1; struct { float a; } s2; s2 = s1; C/C++ do not allow that, but GLSL does seem to want to treat unnamed structs with the same fields as the same type at least during linking (and apparently, some applications require it), so it seems odd to treat them as different types elsewhere.

| | | | | | | | | | | | | | | | | | | | | This changes the logic during the conversion of the declaration list struct S { ... } v; from AST to IR, but should not change the end result. When assigning the type of v, instead of looking `S' up in the symbol table, we read the type from the member variable of ast_struct_specifier. This change is necessary for the subsequent change to how anonymous types are handled. v2: remove a type override when redefining a structure; should be the same type in that case anyway Reviewed-by: Timothy Arceri <[email protected]>
* glsl: fix a race condition when inserting new typesNicolai Hähnle2017-06-132-40/+32
| | | | | | | | | | | | By splitting glsl_type::mutex into two, we can avoid dropping the hash mutex while creating the new type instance (e.g. struct/record, interface). This fixes a time-of-check/time-of-use race where two threads would simultaneously attempt to create the same type but end up with different instances of glsl_type.

* glcpp: fix #undef to match latest spec update and GLSLang implementationIago Toral Quiroga2017-06-071-14/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GLSL ES spec includes the following: "It is an error to undefine or to redefine a built-in (pre-defined) macro name." But desktop GLSL doesn't. This has sparked some discussion in Khronos, and the final conclusion was to update the GLSL 4.50 spec to include the following: "By convention, all macro names containing two consecutive underscores ( __ ) are reserved for use by underlying software layers. Defining or undefining such a name in a shader does not itself result in an error, but may result in unintended behaviors that stem from having multiple definitions of the same name. All macro names prefixed with “GL_” (“GL” followed by a single underscore) are also reserved, and defining or undefining such a name results in a compile-time error." In other words, undefining GL_* names should be an error, but undefining other names with a double underscore in them is not strictly prohibited in desktop GLSL. This patch fixes the preprocessor to apply these rules, following exactly the implementation already present in GLSLang. This fixes some tests in CTS.
