* glsl: fail compilation of compute shaders when unsupportedIago Toral Quiroga2016-10-171-0/+13
| | | | | | | | | | | | | | | | | | | | | | | Generally, we only check for the presence of compute shaders during parsing when we find any language (like layout qualifiers) that are specific to compute shaders, however, it is possible to define an empty compute shader does not use any language specific to compute shaders at all and we should fail the compilation anyway. dEQP checks this. This patch adds a check for compute shader availability after we have parsed the source code. At this point we know the effective GLSL version and also extensions enabled in the shader. Fixes a subcase of the following dEQP tests: dEQP-GLES31.functional.debug.negative_coverage.callbacks.shader.compile_compute_shader dEQP-GLES31.functional.debug.negative_coverage.get_error.shader.compile_compute_shader dEQP-GLES31.functional.debug.negative_coverage.log.shader.compile_compute_shader The tests still fail because there is one more subcase that fails that needs another fix.

* glsl: Kill __intrinsic_atomic_subIan Romanick2016-10-042-9/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Just generate an __intrinsic_atomic_add with a negated parameter. Some background on the non-obvious reasons for the the big change to builtin_builder::call()... this is cribbed from some discussion with Ilia on mesa-dev. Why change builtin_builder::call() to allow taking dereferences and create them here rather than just feeding in the ir_variables directly? The problem is the neg_data ir_variable node would have to be in two lists at the same time: the instruction stream and parameters. The ir_variable node is automatically added to the instruction stream by the call to make_temp. Restructuring the code so that the ir_variables could be in parameters then move them to the instruction stream would have been pretty terrible. ir_call in the instruction stream has an exec_list that contains ir_dereference_variable nodes. The builtin_builder::call method previously took an exec_list of ir_variables and created a list of ir_dereference_variable. All of the original users of that method wanted to make a function call using exactly the set of parameters passed to the built-in function (i.e., call __intrinsic_atomic_add using the parameters to atomicAdd). For these users, the list of ir_variables already existed: the list of parameters in the built-in function signature. This new caller doesn't do that. It wants to call a function with a parameter from the function and a value calculated in the function. So, I changed builtin_builder::call to take a list that could either be a list of ir_variable or a list of ir_dereference_variable. In the former case it behaves just as it previously did. In the latter case, it uses (and removes from the input list) the ir_dereference_variable nodes instead of creating new ones. text data bss dec hex filename 6036395 283160 28608 6348163 60dd83 lib64/i965_dri.so before 6036923 283160 28608 6348691 60df93 lib64/i965_dri.so after Signed-off-by: Ian Romanick <[email protected]> Acked-by: Ilia Mirkin <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code provides for an on-disk cache of objects. Objects are stored and retrieved via names that are arbitrary 20-byte sequences, (intended to be SHA-1 hashes of something identifying for the content). The directory used for the cache can be specified by means of environment variables in the following priority order: $MESA_GLSL_CACHE_DIR $XDG_CACHE_HOME/mesa <user-home-directory>/.cache/mesa By default the cache will be limited to a maximum size of 1GB. The environment variable: $MESA_GLSL_CACHE_MAX_SIZE can be set (at the time of GL context creation) to choose some other size. This variable is a number that can optionally be followed by 'K', 'M', or 'G' to select a size in kilobytes, megabytes, or gigabytes. By default, an unadorned value will be interpreted as gigabytes. The cache will be entirely disabled at runtime if the variable MESA_GLSL_CACHE_DISABLE is set at the time of GL context creation. Many thanks to Kristian Høgsberg <[email protected]> for the initial implementation of code that led to this patch. In particular, the idea of using an mmapped file, (indexed by a portion of the SHA-1), for the efficent implementation of cache_has_key was entirely his idea. Kristian also provided some very helpful advice in discussions regarding various race conditions to be avoided in this code.

They are used in other functions in the same file. So we don't care what the implementation of these stubs is, (they won't be called by glsl_compiler).

* glsl: Immediately inline built-ins rather than generating calls.Kenneth Graunke2016-09-231-24/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the past, we imported the prototypes of built-in functions, generated calls to those, and waited until link time to resolve the calls and import the actual code for the built-in functions. This severely limited our compile-time optimization opportunities: even trivial functions like dot() were represented as function calls. We also had no way of reasoning about those calls; they could have been 1,000 line functions with side-effects for all we knew. Practically all built-in functions are trivial translations to ir_expression opcodes, so it makes sense to just generate those inline. Since we eventually inline all functions anyway, we may as well just do it for all built-in functions. There's only one snag: built-in functions that refer to built-in global variables need those remapped to the variables in the shader being compiled, rather than the ones in the built-in shader. Currently, ftransform() is the only function matching those criteria, so it seemed easier to just make it a special case.

| | | | | | | | | | | | | | | | | | | | | | | We want to check prior to optimization - otherwise we might fail to detect cases where barrier() is in control flow which is always taken (and therefore gets optimized away). We don't currently loop unroll if there are function calls inside; otherwise we might have a problem detecting barrier() in loops that get unrolled as well. Tapani's switch handling code adds a loop around switch statements, so even with the mess of if ladders, we'll properly reject it. Enforcing these rules at compile time makes more sense more sense than link time. Doing it at ast-to-hir time (rather than as an IR pass) allows us to emit an error message with proper line numbers. (Otherwise, I would have preferred the IR pass...) Fixes spec/arb_tessellation_shader/compiler/barrier-switch-always.tesc.
