* gallivm: Allow drivers and state trackers to initialize gallivm LLVM targets v2Tom Stellard2015-10-023-8/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers and state trackers that use LLVM for generating code, must register the targets they use with LLVM's global TargetRegistry. The TargetRegistry is not thread-safe, so all targets must be added to the registry before it can be queried for target information. When drivers and state trackers initialize their own targets, they need a way to force gallivm to initialize its targets at the same time. Otherwise, there can be a race condition in some multi-threaded applications (e.g. glx-multihreaded-shader-compile in piglit), when one thread creates a context for a driver that uses LLVM (e.g. radeonsi) and another thread creates a gallivm context (glxContextCreate does this). The race happens when the driver thread initializes its LLVM targets and then starts using the registry before the gallivm thread has a chance to register its targets. This patch allows users to force gallivm to register its targets by calling the gallivm_init_llvm_targets() function. v2: - Use call_once and remove mutexes and static initializations. - Replace gallivm_init_llvm_{begin,end}() with gallivm_init_llvm_targets().

* i965/shader: Get rid of the shader, prog, and shader_prog fieldsJason Ekstrand2015-10-0219-99/+68
| | | | | | | | | | Unfortunately, we can't get rid of them entirely. The FS backend still needs gl_program for handling TEXTURE_RECTANGLE. The GS vec4 backend still needs gl_shader_program for handling transfom feedback. However, the VS needs neither and we can substantially reduce the amount they are used. One day we will be free from their tyranny. Reviewed-by: Kenneth Graunke <[email protected]>

| | | | | | | | | | | | | Previously, we had a bunch of code in each stage to figure out how many slots we needed in stage_prog_data.param. This code was mostly identical across the stages and had been copied and pasted around. Unfortunately, this meant that any time you did something special, you had to add code for it to each of these places. In particular, none of the stages took subroutines into account; they were working entirely by accident.
