* glsl/builtin: Add alternate versions of atan using new opsNeil Roberts2019-10-121-2/+31
| | | | | | | | | | Adds alternate versions of the atan builtin functions that use ir_unop_atan and ir_binop_atan2 instead of inlining to the IR implementation of the function. These alternatives are selected if the IR is going to be consumed by NIR. In that case the IR ops will be translated to the appropriate NIR op. Reviewed-by: Kristian H. Kristensen <[email protected]>
* glsl: Add helperInvocationEXT() builtinCaio Marcelo de Oliveira Filho2019-09-301-0/+36
| | | | | | | | | | | From EXT_demote_to_helper_invocation, implemented with the existing nir_intrinsic_is_helper_invocation. Such builtin is necessary when using `demote` because we can't redefine the value of gl_HelperInvocation (since it is an input variable). Reviewed-by: Kenneth Graunke <[email protected]>
* mesa/compiler: rework tear down of builtin/typesLionel Landwerlin2019-08-211-6/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | The issue we're running into when running CTS is that glsl types are deleted while builtins depending on them are not. This happens because on one hand we have glsl types ref counted, but builtins are not. Instead builtins are destroyed when unloading libGL or explicitly calling glReleaseShaderCompiler(). This change removes almost entirely any dealing with glsl types ref/unref by letting the builtins deal with it instead. In turn we introduce a builtin ref count mechanism. Each GL context takes a reference on the builtins when compiling a shader for the first time. It releases the reference when the context is destroyed. It can also explicitly release those when glReleaseShaderCompiler() is called. Finally we also take a reference on the glsl types when loading libGL to avoid recreating glsl types too often. v2: Ensure we take a reference if we don't have one in link step (Lionel) Signed-off-by: Lionel Landwerlin <[email protected]> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=110796 Reviewed-by: Eric Anholt <[email protected]> Reviewed-by: Tapani Pälli <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | This extension provides new GLSL built-in function beginFragmentShaderOrderingIntel() that guarantees (taking wording of GL_INTEL_fragment_shader_ordering extension) that any memory transactions issued by shader invocations from previous primitives mapped to same xy window coordinates (and same sample when per-sample shading is active), complete and are visible to the shader invocation that called beginFragmentShaderOrderingINTEL(). One advantage of INTEL_fragment_shader_ordering over ARB_fragment_shader_interlock is that it provides a function that operates as a memory barrie (instead of a defining a critcial section) that can be called under arbitary control flow from any function (in contrast the begin/end of ARB_fragment_shader_interlock may only be called once, from main(), under no control flow.

* 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%.

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

| | | | | | | | | | | | | | | | | | | | | | Builtins are created once and allocated using their own private ralloc context. When reparenting IR that includes builtins, we might be steal bits of builtins. This is problematic because these builtins might now be freed when the shader that includes then last is disposed. This might also lead to inconsistent ralloc trees/lists if shaders are created on multiple threads. Rather than including builtins directly into a shader's IR, we should include clones of them in the ralloc context of the shader that requires them. This fixes double free issues we've been seeing when running shader-db on a big multicore (72 threads) server. v2: Also rename _mesa_glsl_find_builtin_function_by_name() to better reflect how this function is used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | zero/infinity. This addresses several issues of the current atan2 implementation: - Negative zero (and negative denorms which end up getting flushed to zero) isn't handled correctly by the current implementation. The reason is that it does 'y >= 0' and 'x < 0' comparisons to decide on which side of the branch cut the argument is, which causes us to return incorrect results (off by up to 2π) for very small negative values. - There is a serious precision problem for x values of large enough magnitude introduced by the floating point division operation being implemented as a mul+rcp sequence. This can lead to the quotient getting flushed to zero in some cases introducing an error of over 8e6 ULP in the result -- Or in the most catastrophic case will cause us to return NaN instead of the correct value ±π/2 for y=±∞ and x very large. We can fix this easily by scaling down both arguments when the absolute value of the denominator goes above certain threshold. The error of this atan2 implementation remains below 25 ULP in most of its domain except for a neighborhood of y=0 where it reaches a maximum error of about 180 ULP. - It emits a bunch of instructions including no less than three if-else branches per scalar component that don't seem to get optimized out later on. This implementation uses about 13% less instructions on Intel SKL hardware and doesn't emit any control flow instructions. v2: Fix up argument scaling to take into account the range and precision of exotic FP24 hardware.
