* glsl: When assigning to a whole array, mark the array as accessed.Eric Anholt2011-08-151-10/+11
| | | | | | | | | | | | | The vs-varying-array-mat2-col-row-wr test writes a mat2[3] constant to a mat2[3] varying out array, and also statically accesses element 1 of it on the VS and FS sides. At link time it would get trimmed down to just 2 elements, and then codegen of the VS would end up generating assignments to the unallocated last entry of the array. On the new i965 VS backend, that happened to land on the vertex position. Some issues remain in this test on softpipe, i965/old-vs and i965/new-vs on visual inspection, but i965 is passing because only one green pixel is probed, not the whole split green/red quad.

* glsl: Add validations for ir_call.Paul Berry2011-08-151-0/+36
| | | | | | | | | | | | | | | This patch extends ir_validate.cpp to check the following characteristics of each ir_call: - The number of actual parameters must match the number of formal parameters in the signature. - The type of each actual parameter must match the type of the corresponding formal parameter in the signature. - Each "out" or "inout" actual parameter must be an lvalue.

* glsl: Make is_lvalue() and variable_referenced() const.Paul Berry2011-08-152-11/+11
| | | | | | | | | | These functions don't modify the target instruction, so it makes sense to make them const. This allows these functions to be called from ir validation code (which uses const to ensure that it doesn't accidentally modify the IR being validated).

* glsl: Perform implicit type conversions on function call out parameters.Paul Berry2011-08-151-5/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an out parameter undergoes an implicit type conversion, we need to store it in a temporary, and then after the call completes, convert the resulting value. In other words, we convert code like the following: void f(out int x); float value; f(value); Into IR that's equivalent to this: void f(out int x); float value; int out_parameter_conversion; f(out_parameter_conversion); value = float(out_parameter_conversion); This transformation needs to happen during ast-to-IR convertion (as opposed to, say, a lowering pass), because it is invalid IR for formal and actual parameters to have types that don't match. Fixes piglit tests spec/glsl-1.20/compiler/qualifiers/out-conversion-int-to-float.vert and spec/glsl-1.20/execution/qualifiers/vs-out-conversion-*.shader_test, and bug 39651.

* glsl: Modify strategy for accumulating conditions when lowering if-statementsIan Romanick2011-08-151-11/+55
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously if-statements were lowered from inner-most to outer-most (i.e., bottom-up). All assignments within an if-statement would have the condition of the if-statement appended to its existing condition. As a result the assignments from a deeply nested if-statement would have a very long and complex condition. Several shaders in the OpenGL ES2 conformance test suite contain non-constant array indexing that has been lowered by the shader writer. These tests usually look something like: if (i == 0) { value = array[0]; } else if (i == 1) { value = array[1]; } else ... The IR for the last assignment ends up as: (assign (expression bool && (expression bool ! (var_ref if_to_cond_assign_condition) ) (expression bool && (expression bool ! (var_ref if_to_cond_assign_condition@20) ) (expression bool && (expression bool ! (var_ref if_to_cond_assign_condition@22) ) (expression bool && (expression bool ! (var_ref if_to_cond_assign_condition@24) ) (var_ref if_to_cond_assign_condition@26) ) ) ) ) (x) (var_ref value) (array_ref (var_ref array) (constant int (5))) The Mesa IR that is generated from this is just as awesome as you might expect. Three changes are made to the way if-statements are lowered. 1. Two condition variables, if_to_cond_assign_then and if_to_cond_assign_else, are created for each if-then-else structure. The former contains the "positive" condition, and the later contains the "negative" condtion. This change was implemented in the previous patch. 2. Each condition variable is added to a hash-table when it is created. 3. When lowering an if-statement, assignments to existing condtion variables get the current condition anded. This ensures that nested condition variables are only set to true when the condition variable for all outer if-statements is also true. Changes #1 and #3 combine to ensure the correctness of the resulting code. 4. When a condition assignment is encountered with a condition that is a dereference of a previously added condition variable, the condition is not modified. Change #4 prevents the continuous accumulation of conditions on assignments. If the original if-statements were: if (x) { if (a && b && c && d && e) { ... } else { ... } } else { if (g && h && i && j && k) { ... } else { ... } } The lowered code will be if_to_cond_assign_then@1 = x; if_to_cond_assign_then@2 = a && b && c && d && e && if_to_cond_assign_then@1; ... if_to_cond_assign_else@2 = !if_to_cond_assign_then && if_to_cond_assign_then@1; ... if_to_cond_assign_else@1 = !if_to_cond_assign_then@1; if_to_cond_assign_then@3 = g && h && i && j; && if_to_cond_assign_else@1; ... if_to_cond_assign_else@3 = !if_to_cond_assign_then && if_to_cond_assign_else@1; ... Depending on how instructions are emitted, there may be an extra instruction due to the duplication of the '&& if_to_cond_assign_{then,else}@1' on the nested else conditions. In addition, this may cause some unnecessary register pressure since in the simple case (where the nested conditions are not complex) the nested then-condition variables are live longer than strictly necessary. Before this change, one of the shaders in the OpenGL ES2 conformance test suite's acos_float_frag_xvary generated 348 Mesa IR instructions. After this change it only generates 124. Many, but not all, of these instructions would have also been eliminated by CSE. Reviewed-by: Eric Anholt <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | Now the condition (for the then-clause) and the inverse condition (for the else-clause) get written to separate temporary variables. In the presence of complex conditions, this shouldn't result in more code being generated. If the original if-statement was if (a && b && c && d && e) { ... } else { ... } The lowered code will be if_to_cond_assign_then = a && b && c && d && e; ... if_to_cond_assign_else = !if_to_cond_assign_then; ...

* egl: Native Display autodetectionBenjamin Franzke2011-08-155-8/+117
| | | | | | | | | | | | | | | | | | | | | | | | EGL doesnt define howto manage different native platforms. So mesa has a builtime configurable default platform, whith non-standard envvar (EGL_PLATFORM) overwrites. This caused unneeded bugreports, when EGL_PLATFORM was forgotten. Detection is grouped into basic types of NativeDisplays (which itself needs to be detected). The final decision is based on characteristcs of these basic types: File Desciptor based platforms (fbdev): - fstat(2) to check for being a fd that belongs to a character device - check kernel subsystem (todo) Pointer to structuctures (x11, wayland, drm/gbm): - mincore(2) to check whether its valid pointer to some memory. - magic elements (e.g. pointers to exported symbols): o wayland display stores interface type pointer (first elm.) o gbm stores pointer to its constructor (first elm.) o x11 as a fallback (FIXME?)
