* mesa/compiler: rework tear down of builtin/typesLionel Landwerlin2019-08-211-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | 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]>
* glsl: report no function instead of empty candidate listErik Faye-Lund2019-07-251-2/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When generating the error message for a missing function error where all available overloads were missing due to a too low GLSL version, we used to report something like this: ---8<--- 0:224(14): error: no matching function for call to `textureCubeLod(samplerCube, vec3, float)'; candidates are: 0:224(14): error: type mismatch ---8<--- This is a pretty confusing error message, and can throw people off when debugging. So let's instead check if any overload is available before we decide what to print. This allow us to report something like this instead: ---8<--- 0:224(14): error: no function with name 'textureCubeLod' 0:224(14): error: type mismatch ---8<--- This is arguably easier to understand for programmers, and doesn't send you on a wild goose chase to figure out what argument is wrong just because you stopped reading the message prematurely. I'm of course referring to a friend, not me. For sure. I would never do that. Signed-off-by: Erik Faye-Lund <[email protected]> Reviewed-by: Matt Turner <[email protected]>

| | | | | | | | | | | | | | | In GLES, we currently either need an exact match with a local function, or an exact match with a builtin. However, if we add support for implicit conversions for GLES shaders, we also need to fall back to a non-exact match in the case where there were no builtin match either. Luckily, we already have a variable ready with this, so let's just return it if the builtin-search failed.

* glsl: pass mem_ctx to constant_expression_value(...) and friendsTimothy Arceri2017-08-111-6/+11
| | | | | | | | | | | | | | | | | | | | 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.

* 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. On Skylake: total instructions in shared programs: 12023491 -> 12024010 (0.00%) instructions in affected programs: 77595 -> 78114 (0.67%) helped: 97 HURT: 309 total cycles in shared programs: 137239044 -> 137295498 (0.04%) cycles in affected programs: 16714026 -> 16770480 (0.34%) helped: 4663 HURT: 4923 while these statistics are in the wrong direction, the number of hurt programs is small (309 / 41282 = 0.75%), and I don't think anything can be done about it.

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