* glsl: Unify ir_constant::const_elements and ::componentsIan Romanick2017-09-196-113/+24
| | | | | | | | | | There was no reason to treat array types and record types differently. Unifying them saves a bunch of code and saves a few bytes in every ir_constant.

* glsl: Rename ir_constant::array_elements to ::const_elementsIan Romanick2017-09-196-22/+22
| | | | | | | | | | | The next patch will unify ::array_elements and ::components, so the name ::array_elements wouldn't be appropriate. A lot of things use the names array_elements and components, so grepping for either is pretty useless.

* glsl: buffer variables can be readonly and writeonlyJuan A. Suarez Romero2017-09-191-11/+3
| | | | | | | | | | | | | | | | | | | | | | | | In GLSL ES 3.10 session 4.9 [Memory Access Qualifiers], it has the following description: "A variable could be qualified as both readonly and writeonly, disallowing both read and write, but still be passed to imageSize() to have the size queried.". This is for image variable, but not for buffer variables. According to https://github.com/KhronosGroup/OpenGL-API/issues/7 Khronos intent is to allow both readonly and writeonly in buffer variables, and as such it will update the GLSL specification. This commit address this issue, and fixes: KHR-GL{43,44,45}.shader_storage_buffer_object.basic-readonly-writeonly KHR-GLES31.core.shader_storage_buffer_object.basic-readonly-writeonly v2: set correctly fields[i] memory flags (Samuel Pitoiset).

* glsl: avoid accessing invalid memory after get_variable_being_redeclared()Iago Toral Quiroga2017-09-141-20/+19
| | | | | | | | | | | | | | After get_variable_being_redeclared() has been called, it is no longer safe to access the original variable pointer, since its memory might have been freed. Since callers of this function should only be accessing the variable pointer returned by the function, avoid potential bugs by re-assigning the original variable pointer to the result of the function call, making it impossible for the remaining code to access an invalid variable pointer.

* glsl: make the redeclared variable NULL if it is deletedIago Toral Quiroga2017-09-141-3/+6
| | | | | | | | | | | | | | get_variable_being_redeclared() can delete the original variable in a specific scenario. The code sets it to NULL after this so other code in that same function doesn't try to access trashed memory after the fact, however, the copy of that variable in the caller code won't see any of this making it very easy to overlook. Make the function a bit safer by taking a pointer to the original variable so we can also make NULL the caller's pointer to the variable if this function deletes it.

* 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.

| | | | | | | | | | | | | | | | | | | | | The cloning was introduced in f81ede469910d to fix a problem with shaders including IR that was owned by builtins.

| | | | | | | | | | | | | | | | | | | | 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.
