* meson: Add build Intel "anv" vulkan driverDylan Baker2017-09-271-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows building and installing the Intel "anv" Vulkan driver using meson and ninja, the driver has been tested against the CTS and has seems to pass the same series of tests (they both segfault when the CTS tries to run wayland wsi tests). There are still a mess of TODO, XXX, and FIXME comments in here. Those are mostly for meson bugs I'm trying to fix, or for additional things to implement for other drivers/features. I have configured all intermediate libraries and optional tools to not build by default, meaning they will only be built if they're pulled in as a dependency of a target that will actually be installed) this allows us to avoid massive if chains, while ensuring that only the bits that need to be built are. v2: - enable anv, x11, and wayland by default - add configure option to disable valgrind v3: - fix typo in meson_options (Nicholas) v4: - Remove dead code (Eric) - Remove change to generator that was from v0 (Eric) - replace if chain with loop (Eric) - Fix typos (Eric) - define HAVE_DLOPEN for both libdl and builtin dl cases (Eric) v5: - rebase on util string buffer implementation Signed-off-by: Dylan Baker <[email protected]> Reviewed-by: Eric Anholt <[email protected]> (v4)

| | | | | | | | | | | | | Migrate removal of line continuations to string_buffer.

| | | | | | | | | | | | | | | | | Prevent an overflow caused by too many output variables. To limit the scope of the issue, write to the assigned array only for the non-ES fragment shader path, which is the only place where it's needed. Since the function will bail with an error when output variables with overlapping components are found, (max # of FS outputs) * 4 is an upper limit to the space we need. Found by address sanitizer.

* 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).

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

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: 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.

| | | | | | | | | | | We are currently copying the name for each member dereference but we can just share a single instance of the string provided by the type. This change also stops us recalculating the field index repeatedly. Reviewed-by: Thomas Helland <[email protected]>
