2007-03-26i915tex: Make sure renderbuffers don't get deleted when flipping them.Michel Dänzer
Since the recent renderbuffer refcounting fixes it's no longer sufficient to just remove the old renderbuffer from the framebuffer and then add the new one because the former may decrease the reference count to 0 and delete the old renderbuffer.

The texture_rectangle fix introduced a bug where every texture instruction caused a new indirection.

2007-03-24r300: Fix texture coordinate calculation for rectangle texturesNicolai Haehnle
R300 hardware takes texcoords in the range 0..1 even for rectangle textures. Previously, the necessary texcoord conversion was applied to the texture coordinate during vertex processing in a render stage. This is obviously wrong when fragment programs are used, which can calculate arbitrary coordinates for TEX instructions. Therefore, we now inject an appropriate MUL instruction before a TEX that reference a rectangle texture.
2007-03-24r300: No assertion when accessing incomplete texture images.Nicolai Haehnle
There used to be an assertion when a fragment program accesses an incomplete texture image. Work around this assertion. Note: I am unsure whether this workaround produces the desired result (0,0,0,1) on all hardware.

2007-03-23Implement alpha buffer copy for SwapBuffers().Brian
Nicolai writes: When the pixmap pixel format has no alpha channel, the x11 driver (software rendering) adds a wrapped alpha channel on request. During SwapBuffers, this alpha channel is not copied from back to front, which means that the front buffer doesn't really contain the contents that the back buffer previously contained. A subsequent glReadPixels from the front buffer will return an incorrect result. The following patch attempts to fix this.

2007-03-23Fix issues related to the 'continue' statement.Brian
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.

2007-03-23Add the ability to generate programs that doesn't use condition codes.Brian
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.

2007-03-22Overhaul emit_compare() function.Brian
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.
2007-03-22First pass at implementing structure compares.Brian
Need to improve this. There may be holes in a structure so we can't just blindly compare the full 4-float registers.
