|
* Implement do/while loops. Replace IR_CJUMP with IR_CJUMP0 and IR_CJUMP1 soBrian2007-01-193-16/+79
| | | | we can either jump on zero, or non-zero predicate.
* Rewrite normalize(vec3/vec4) to use one less register.Brian2007-01-192-335/+346

|
* change while-loop to create new scope for loop body, per specBrian2007-01-192-3/+3
|
* Implement constant sharing so that 4 float constants can share a singleBrian2007-01-182-12/+19
| | | | float[4] register slot.
* _mesa_add_unnamed_constant() now tries to re-use constants already inBrian2007-01-181-30/+57
| | | | the parameter list.
* Reimplement code for swizzling so that expressions like (p+q).x for vectors ↵Brian2007-01-184-91/+129
| | | | p and q works correctly.
* rewrite a bunch of assignment operators (like +=)Brian2007-01-182-488/+495
|
* remove swizzle param from new_var()Brian2007-01-181-5/+5
|
* rewrite additional matrix-related functions to reduce register needsBrian2007-01-172-468/+463
|
* rewrite mat4 * mat4 operator to use fewer tempsBrian2007-01-172-383/+430
|
* do bounds check in _slang_push_var_table(), added commentBrian2007-01-171-1/+3
|
* rewrite matrix constructorsBrian2007-01-172-787/+928
|
* handle var size > 4 in _slang_pop_var_table()Brian2007-01-171-3/+7
|
* Rewrite a bunch of constructors. It's now important that the firstBrian2007-01-172-713/+801
| | | | | | | constructor for any given type be the one that takes the most parameters as this is the constructor that'll be used when there's no perfect match to the caller's arguments. See the _slang_adapt_call() function for details.
* _slang_gen_function_call_name() now tries to adapt function calls (expandBrian2007-01-172-12/+44
| | | | vectors, insert casts) when a perfect match isn't found.
* New _slang_adapt_call() function.Brian2007-01-172-0/+154
| | | | | | | | | | | | This is used to modify function calls (when possible) to make the arguments map to the function parameters. This includes "unrolling" vector types and doing casts. Example: vec2 v2 = vec2(1.2, 3.4) ivec3 iv = ivec3(false, v2); Is converted into: ivec3 iv = ivec3(int(false), int(v2[0]), int(v2[1]))
* code clean-up, re-org. Added IR_F_TO_I support.Brian2007-01-171-90/+112
|
* added IR_F_TO_I, update commentsBrian2007-01-171-3/+4

|
* fix _slang_gen_subscript() for the case when a simple vector is accessed as ↵Brian2007-01-161-17/+52
| | | | an array: convert index to a swizzle/writemask
* Reimplement the post-increment/decrement functions.Brian2007-01-153-151/+190
| | | | | | Instead of defining functions with an extra dummy parameter to distinguish from the pre-incr/decr functions, just use new function names: __postIncr and __postDecr.
* Implement the ++var and --var operators, improve some constructors.Brian2007-01-153-811/+843

|
* Rework code related to temp register allocation, both for user variablesBrian2007-01-1312-477/+496
| | | | | | and expression temporarires. Much better register utilization now. Lots of other fixes. The OpenGL GLSL "orange book" brick shader demo works now.
* slang_variable_scope now stores array of pointers to slang_variables.Brian2007-01-136-39/+63
