* i965/skl: Implement WaDisable1DDepthStencilNeil Roberts2015-02-101-0/+12
| | | | | | | | | | | Skylake+ doesn't support setting a depth buffer to a 1D surface but it does allow pretending it's a 2D texture with a height of 1 instead. This fixes the GL_DEPTH_COMPONENT_* tests of the copyteximage piglit test (and also seems to avoid a subsequent GPU hang).

| | | | | | | | | | | | | non-renderbuffers. Null surfaces are going to be useful to have something to point unbound image units to, as the ARB_shader_image_load_store extension requires us to behave deterministically in cases where some shader tries to access an unbound image unit: Invalid stores and atomics are supposed to be discarded and invalid loads are supposed to return zero, which is precisely what the null surface does.

| | | | | | | | | | | | One should be able to manipulate i965 IR without pulling the whole FS/VEC4 visitor classes -- Optimization passes and other transformations would ideally be visitor-agnostic.

| | | | | | | | | | | | | Right now virtual GRF book-keeping and allocation is performed in each visitor class separately (among other hundred different things), leading to duplicated logic in each visitor and preventing layering as it forces any code that manipulates i965 IR and needs to allocate virtual registers to depend on the specific visitor that happens to be used to translate from GLSL IR. v2: Use realloc()/free() to allocate VGRF book-keeping arrays (Connor).

| | | | | | | | | | | | The old way made it impossible for the optimizer to reason about what was going on. The new way is the same number of instructions (the neg gets folded into the cvt) but enables the optimizer to be cleverer if comparing to a constant (most common case). [The optimizer is presently not sufficiently clever to work this out, but it could relatively easily be made to be.
