* util/disk_cache: rename mesa cache dir and introduce cache versioningTimothy Arceri2017-08-251-2/+4
| | | | | | | | | | | | | | | | | | Steam is already analysing cache items, unfortunatly we did not introduce a versioning mechanism for identifying structural changes to cache entries earlier so the only way to do so is to rename the cache directory. Since we are renaming it we take the opportunity to give the directory a more meaningful name. Adding a version field to the header of cache entries will help us to avoid having to rename the directory in future. Please note this is versioning for the internal structure of the entries as defined in disk_cache.{c,h} as opposed to the structure of the data provided to the disk cache by the GLSL compiler and the various driver backends.

* glsl: stop cloning builtin fuctions _mesa_glsl_find_builtin_function()Timothy Arceri2017-08-111-10/+1
| | | | | | | | | | | | | | | | | | | | | The cloning was introduced in f81ede469910d to fix a problem with shaders including IR that was owned by builtins. However the approach of cloning the whole function each time we reference a builtin lead to a significant reduction in the GLSL IR compilers performance. The previous patch fixes the ownership problem in a more precise way. So we can now remove this cloning. Testing on a Ryzen 7 1800X shows a ~15% decreases in compiling the Deus Ex: Mankind Divided shaders on radeonsi (which take 5min+ on some machines). Looking just at the GLSL IR compiler the speed up is ~40%.

* glsl: pass mem_ctx to constant_expression_value(...) and friendsTimothy Arceri2017-08-1120-86/+159
| | | | | | | | | | | | | | | | | | | | The main motivation for this is that threaded compilation can fall over if we were to allocate IR inside constant_expression_value() when calling it on a builtin. This is because builtins are shared across the whole OpenGL context. f81ede469910d worked around the problem by cloning the entire builtin before constant_expression_value() could be called on it. However cloning the whole function each time we referenced it lead to a significant reduction in the GLSL IR compiler performance. This change along with the following patch helps fix that performance regression. Other advantages are that we reduce the number of calls to ralloc_parent(), and for loop unrolling we free constants after they are used rather than leaving them hanging around.

| | | | | | | | | | | | | | | | | | | Extra validation is added to ir_validate to make sure this is always updated to the correct numer of operands, as passes like lower_instructions modify the instructions directly rather then generating a new one. The reduction in time is so small that it is not really measurable.

* 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).

| | | | | | | | | | | | | | | | | | | | | _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.
