* glsl: Add a helper function for determining if an rvalue could be a saturate.Eric Anholt2010-11-192-0/+58
| | | | | | Hardware pretty commonly has saturate modifiers on instructions, and this can be used in codegen to produce those, without everyone else needing to understand clamping other than min and max.
* glsl: Fix type of label 'default' in switch statement.Vinson Lee2010-11-191-1/+1
|
* glsl: Add lower_vector.cpp to SConscript.Vinson Lee2010-11-191-0/+1
|
* glsl: Fix matrix constructors with vector parametersIan Romanick2010-11-191-9/+9
| | | | | | | When the semantics of write masks in assignments were changed, this code was not correctly updated. Fixes piglit test glsl-mat-from-vec-ctor-01.
* glsl: Combine many instruction lowering passes into one.Kenneth Graunke2010-11-199-376/+273
| | | | | | | This should save on the overhead of tree-walking and provide a convenient place to add more instruction lowering in the future. Signed-off-by: Ian Romanick <[email protected]>
* glsl: Simplify a type check by using type->is_integer().Kenneth Graunke2010-11-191-2/+1
|
* glsl: Add ir_quadop_vector expressionIan Romanick2010-11-199-6/+327
| | | | | | | | | | The vector operator collects 2, 3, or 4 scalar components into a vector. Doing this has several advantages. First, it will make ud-chain tracking for components of vectors much easier. Second, a later optimization pass could collect scalars into vectors to allow generation of SWZ instructions (or similar as operands to other instructions on R200 and i915). It also enables an easy way to generate IR for SWZ instructions in the ARB_vertex_program assembler.
* glsl: Add unary ir_expression constructorIan Romanick2010-11-192-0/+21
|
* glsl: Add ir_rvalue::is_negative_one predicateIan Romanick2010-11-192-3/+58
|
* glsl: Eliminate assumptions about size of ir_expression::operandsIan Romanick2010-11-195-6/+9
| | | | This may grow in the near future.
* glsl: Add ir_unop_sin_reduced and ir_unop_cos_reducedIan Romanick2010-11-194-0/+8
| | | | | | | | | | | | The operate just like ir_unop_sin and ir_unop_cos except that they expect their inputs to be limited to the range [-pi, pi]. Several GPUs require this limited range for their sine and cosine instructions, so having these as operations (along with a to-be-written lowering pass) helps this architectures. These new operations also matche the semantics of the GL_ARB_fragment_program SCS instruction. Having these as operations helps in generating GLSL IR directly from assembly fragment programs.
* glsl: Make is_zero and is_one virtual methods of ir_rvalueIan Romanick2010-11-182-21/+36
| | | | | This eliminates the need in some cames to validate that an rvalue is an ir_constant before checking to see if it's 0 or 1.
* glsl: Fix 'control reaches end of non-void function' warning.Vinson Lee2010-11-171-0/+3
| | | | | | | Fix this GCC warning. ir.cpp: In static member function 'static unsigned int ir_expression::get_num_operands(ir_expression_operation)': ir.cpp:199: warning: control reaches end of non-void function
* glsl: Improve usage message for glsl_compilerChad Versace2010-11-171-9/+19
| | | | | | | | | | | | | | | | | The new usage message lists possible command line options. (Newcomers to Mesa currently have to trawl through the source to find the command line options, and we should save them from that trouble.) Example Output -------------- usage: ./glsl_compiler [options] <file.vert | file.geom | file.frag> Possible options are: --glsl-es --dump-ast --dump-hir --dump-lir --link
* glsl: Refactor get_num_operands.Kenneth Graunke2010-11-172-71/+21
| | | | | | | | | | This adds sentinel values to the ir_expression_operation enum type: ir_last_unop, ir_last_binop, and ir_last_opcode. They are set to the previous one so they don't trigger "unhandled case in switch statement" warnings, but should never be handled directly. This allows us to remove the huge array of 1s and 2s in ir_expression::get_num_operands().
* glsl: Remove the ir_binop_cross opcode.Kenneth Graunke2010-11-174-21/+8
|
* Refresh autogenerated file builtin_function.cpp.Kenneth Graunke2010-11-171-3/+5
|
* glsl: Reimplement the "cross" built-in without ir_binop_cross.Kenneth Graunke2010-11-171-3/+5
| | | | | | We are not aware of any GPU that actually implements the cross product as a single instruction. Hence, there's no need for it to be an opcode. Future commits will remove it entirely.
* Regenerate glcpp parser.Kenneth Graunke2010-11-171-85/+90
|
* glsl: Unconditionally define GL_FRAGMENT_PRECISION_HIGH in ES2 shaders.Kenneth Graunke2010-11-171-1/+6
| | | | | | | | | This is really supposed to be defined only if the driver supports highp in the fragment shader - but all of our current ES2 implementations do. So, just define it. In the future, we'll need to add a flag to gl_context and only define the macro if the flag is set. "Fixes" freedesktop.org bug #31673.
* glsl: Fix Doxygen tag \file in recently renamed filesChad Versace2010-11-1723-23/+23
|
* glsl: Fix erroneous cast in ast_jump_statement::hir()Chad Versace2010-11-171-2/+1
| | | | | | Return values were erroneously cast from (ir_rvalue*) to (ir_expression*). NOTE: This is a candidate for the 7.9 branch.
* glsl: Fix constant expression handling for <, >, <=, >= on vectors.Kenneth Graunke2010-11-171-48/+60
| | | | | | | | | | | | | | | | | ir_binop_less, ir_binop_greater, ir_binop_lequal, and ir_binop_gequal are defined to work on vectors as well as scalars, as long as the two operands have the same type. This is evident from both ir_validate.cpp and our use of these opcodes in the GLSL lessThan, greaterThan, lessThanEqual, greaterThanEqual built-in functions. Found by code inspection. Not known to fix any bugs. Presumably, our tests for the built-in comparison functions must pass because C.E. handling is done on the ir_call of "greaterThan" rather than the inlined opcode. The C.E. handling of the built-in function calls is correct. NOTE: This is a candidate for the 7.9 branch.
* Refresh autogenerated glcpp parser.Kenneth Graunke2010-11-162-200/+210
|
* glcpp: Define GL_FRAGMENT_PRECISION_HIGH if GLSL version >= 1.30.Kenneth Graunke2010-11-161-0/+3
| | | | Per section 4.5.4 of the GLSL 1.30 specification.
* glsl: Simplify generation of swizzle for vector constructorsIan Romanick2010-11-161-6/+5
|
* glsl: Refactor is_vec_{zero,one} to be methods of ir_constantIan Romanick2010-11-163-68/+101
| | | | These predicates will be used in other places soon.
* glsl: Add ir_constant_expression.cpp to SConscript.Vinson Lee2010-11-151-0/+1
| | | | | | This was accidentally removed in commit 32aaf89823de11e98cb59d5ec78c66cd3e74bcd4. Fixes SCons builds.
* glsl: remove opt_constant_expression.cpp from SConscriptBrian Paul2010-11-151-3/+2
| | | | And alphabetize the opt_* files.
* glsl: fix assorted MSVC warningsBrian Paul2010-11-151-13/+13
|
* glsl: Rename various ir_* files to lower_* and opt_*.Kenneth Graunke2010-11-1525-47/+47
| | | | | This helps distinguish between lowering passes, optimization passes, and other compiler code.
* glsl: Remove unused and out of date Makefile.am.Kenneth Graunke2010-11-151-81/+0
| | | | | This was from when glsl2 lived in a separate repository and used automake.
* glsl: Add constant expression handling for asinh, acosh, and atanh.Kenneth Graunke2010-11-151-0/+12
|
* glsl: Refresh autogenerated file builtin_function.cpp.Kenneth Graunke2010-11-151-2999/+189
|
* glsl: Implement the asinh, acosh, and atanh built-in functions.Kenneth Graunke2010-11-155-4/+79
|
* generate_builtins.py: Fix inconsistent use of tabs and spaces warning.Kenneth Graunke2010-11-151-3/+3
|
* glsl: Refresh autogenerated lexer and parser files.Kenneth Graunke2010-11-153-2015/+2183
| | | | For the last three commits.
* glsl: Add support for the 'u' and 'U' unsigned integer suffixes.Kenneth Graunke2010-11-151-6/+8
|
* glsl: Add new keywords and reserved words for GLSL 1.30.Kenneth Graunke2010-11-152-0/+22
|
* glsl: Rework reserved word/keyword handling in the lexer.Kenneth Graunke2010-11-151-117/+122
| | | | | | | | | | | | | | | | This consolidates the TOKEN_OR_IDENTIFIER and RESERVED_WORD macros into a single KEYWORD macro. The old TOKEN_OR_IDENTIFIER macros handled the case of a word going from an identifier to a keyword; the RESERVED_WORD macro handled a word going from a reserved word to a language keyword. However, neither could properly handle samplerBuffer (for example), which is an identifier in 1.10 and 1.20, a reserved word in 1.30, and a keyword in 1.40 and on. Furthermore, the existing macros didn't properly handle reserved words in GLSL ES 1.00. The best they could do was return a token (rather than an identifier), resulting in an obtuse parser error, rather than a user-friendly "you used a reserved word" error message.
* glsl: Convert glsl_type::base_type from #define'd constants to an enum.Kenneth Graunke2010-11-152-12/+14
| | | | | This is nice because printing type->base_type in GDB will now give you a readable name instead of a number.
* glsl: Remove GLSL_TYPE_FUNCTION define.Kenneth Graunke2010-11-152-9/+2
| | | | | | | Functions are not first class objects in GLSL, so there is never a value of function type. No code actually used this except for one function which asserted it shouldn't occur. One comment mentioned it, but was incorrect. So we may as well remove it entirely.
* glsl: Free the loop state context when we free the loop state.Eric Anholt2010-11-111-0/+1
| | | | | | | | Since this was talloced off of NULL instead of the compile state, it was a real leak over the course of the program. Noticed with valgrind --leak-check=full --show-reachable=yes. We should really change these passes to generally get the compile context as an argument so simple mistakes like this stop mattering.
* glsl: fix crash in loop analysis when some controls can't be determinedAras Pranckevicius2010-11-111-0/+3
| | | | Fixes loop-07.frag.
* glsl: Remove unnecessary "unused variable" warning suppression.Kenneth Graunke2010-11-091-3/+0
| | | | The "instructions" variable -is- used, so the cast to void can go away.
* glsl: Fix incorrect gl_type of sampler2DArray and sampler1DArrayShadowIan Romanick2010-11-091-2/+2
| | | | NOTE: this is a candidate for the 7.9 branch.
* glsl: Fix ir_expression::constant_expression_value()Chad Versace2010-11-091-0/+3
| | | | | When the type of the ir_expression is error_type, return NULL. This fixes bug 31371.
* ir_dead_functions: Actually free dead functions and signatures.Kenneth Graunke2010-11-081-0/+2
| | | | | This makes linked shaders use around 36k less memory since the built-in prototypes are now freed.
* r600g: implement texture_get_handle (needed for eglExportDRMImageMESA)Benjamin Franzke2010-11-083-261/+250
|
* ir_reader: Fix some potential NULL pointer dereferences.Kenneth Graunke2010-11-031-4/+4
| | | | Found by inspection.
