* glsl: xfb_stride applies to buffers, not block membersJuan A. Suarez Romero2017-08-011-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we have an interface block like: layout (xfb_buffer = 0, xfb_offset = 0) out Block { vec4 var1; layout (xfb_stride = 48) vec4 var2; vec4 var3; }; According to ARB_enhanced_layouts spec: "The *xfb_stride* qualifier specifies how many bytes are consumed by each captured vertex. It applies to the transform feedback buffer for that declaration, whether it is inherited or explicitly declared. It can be applied to variables, blocks, block members, or just the qualifier out. [ ...] While *xfb_stride* can be declared multiple times for the same buffer, it is a compile-time or link-time error to have different values specified for the stride for the same buffer." This means xfb_stride actually applies to the buffer, and not to the individual components. In the above example, it means that var2 consumes 16 bytes, and var3 is at offset 32. This has been confirmed also by John Kessenich, the main contact for the ARB_enhanced_layouts specs, and also because this commit fixes: GL45.enhanced_layouts.xfb_block_member_stride This commit is in practice a revert of 598790e8564 (glsl: apply xfb_stride to implicit offsets for ifc block members).

* nir: Use nir_src_copy instead of direct assignments.Kenneth Graunke2017-07-183-9/+9
| | | | | | | | | | | | | | | If the source is an indirect register, there is ralloc'd data. Copying with a direct assignment will copy the pointer, but the data will still belong to the old instruction's memory context. Since we're lowering and throwing away instructions, that could free the data by mistake. Instead, use nir_src_copy, which properly handles this. This is admittedly not a common case, so I think the bug is real, but unlikely to be hit. Cc: [email protected] Reviewed-by: Matt Turner <[email protected]>

* glsl: check if any of the named builtins are available firstIlia Mirkin2017-07-053-4/+14
| | | | | | | | | | | | | | | | | | | | | _mesa_glsl_has_builtin_function is used to determine whether any variant of a builtin are available, for the purpose of enforcing the GLSL ES 3.00+ rule that overloads or overrides of builtins are disallowed. However the builtin_builder contains information on all builtins, irrespective of parse state, or versions, or extension enablement. As a result we would say that a builtin existed even if it was not actually available. To resolve this, first check if at least one signature is available for a builtin before returning true.
