| * When computing render_inputs_bitset, omit primary color if we have a ↵Brian2007-03-241-10/+11
| | | | | | | | fragment program and it doesn't need FRAG_ATTRIB_COL0. Silences valgrind warnings.

| * Fix issues related to the 'continue' statement.Brian2007-03-233-52/+126
| | | | | | | | | | | | | | | | IR_LOOP now has two children: the body code, and the tail code. Tail code is the "i++" part of a for-loop, or the expression at the end of a "do {} while(expr);" loop. "continue" translates into: "execute tail code; CONT;" Also, the test for infinite do/while loops was incorrect.
| * consolidate some codeBrian2007-03-231-7/+2
| |
| * Add the ability to generate programs that doesn't use condition codes.Brian2007-03-238-51/+176
| | | | | | | | | | | | | | ctx->Shader.EmitCondCodes determines if we use condition codes. If not, IF statement uses first operand's X component as the condition. Added OPCODE_BRK0, OPCODE_BRK1, OPCODE_CONT0, OPCODE_CONT1 to handle the common cases of conditional break/continue.

| * Overhaul emit_compare() function.Brian2007-03-223-36/+143
| | | | | | | | | | | | | | | | Previously, comparing vec2, vec3, vec4 was broken. Added IR_EQUAL, IR_NOTEQUAL nodes/operators to compute boolean equality/inequality vs. IR_SEQUAL/IR_SNEQUAL which work component-wise. Use IR_EQUAL/IR_NOTEQUAL for the == and != operators. To compute vec4 equality, use SNE, DP4, SEQ instruction sequence.
| * First pass at implementing structure compares.Brian2007-03-221-9/+28
| | | | | | | | | | Need to improve this. There may be holes in a structure so we can't just blindly compare the full 4-float registers.
| * use _mesa_copy_instructions()Brian2007-03-224-8/+5

| * In _mesa_add_unnamed_constant() and _mesa_lookup_parameter_constant() allow ↵Brian2007-03-223-43/+61
| | | | | | | | | | | | | | | | swizzleOut==NULL. There are times when we don't want to allow swizzling when searching for or adding vector constants. Passing NULL for swizzleOut disables swizzling. This fixes a constant/swizzle bug in link_uniform_vars().

| | | | | | | | | | | | This fixes a performance regression introduced early in glsl-compiler-1 work.

| | | | | | | | | | | | | | | | | | | | | | | | the ptr in the node for reuse. This can save a tremendous amount of time when resolving types in complex expressions. One particular shader was taking several minutes to compile but now compiles almost instantaneoulsy.
