* i965/fs: Implement texture projection support.Kenneth Graunke2015-03-251-1/+10
| | | | | | | | | | | | | Our fragment program backend implements support for TXP directly, and there's no NIR lowering pass to remove the projection. When we switch fragment program support over to NIR, we need to support it somehow. It's easy enough to support directly. v2: Split out offset/tex_offset rename (requested by Jordan).

| | | | | | | | | | fs_visitor::nir_emit_texture() created an fs_reg variable called offset, which shadowed the offset() helper function in brw_ir_fs.h.

| | | | | | | | | | | try_copy_propagate() was checking the bit of the saturate mask for the arg-th component of the source to decide whether the whole source should be saturated (WTF?). We need to swizzle the original saturate mask and check that for all enabled channels the saturate flag is either set or unset, as we cannot saturate a subset of destination components only.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies the src_reg/dst_reg conversion constructors using the swizzle utils introduced in a previous patch. It also makes them more useful by changing their semantics slightly: dst_reg(src_reg) used to set the writemask to XYZW if the src_reg swizzle was anything other than XXXX, which was almost certainly not what the caller intended if the swizzle was non-trivial. After this patch the same components that are present in the swizzle will be enabled in the resulting writemask. src_reg(dst_reg) used to set the first components of the swizzle to the enabled components of the writemask and then replicate the last enabled component to fill the swizzle, which, in cases where the writemask didn't have exactly the first n components set, would in general not be compatible with the original dst_reg. E.g.: | ADD(tmp, src_reg(tmp), src_reg(1)); would *not* do what one would expect (add one to each of the enabled components of tmp) if tmp didn't have a writemask of the described form (e.g. YZ, YW, XZW would all fail). This pattern actually occurs in many different places in the VEC4 back-end, it's a wonder that it hasn't caused piglit failures until now. After this patch src_reg(dst_reg) will construct a swizzle with each enabled component at its natural position (e.g. Y at the second position, Z at the third, and so on). The resulting swizzle will behave like the identity when used in any instruction with the original writemask. I've manually verified that *none* of the callers of both conversion constructors were relying on the previous broken semantics. There are no piglit regressions on any generation.

This is going to be useful because the Gen7+ uniform and varying pull constant, texturing, typed and untyped surface read, write, and atomic generation code on the vec4 and fs back-end all require the same logic to handle conditionally indirect surface indices. In pseudocode: | if (surface.file == BRW_IMMEDIATE_VALUE) { | inst = brw_SEND(p, dst, payload); | set_descriptor_control_bits(inst, surface, ...); | } else { | inst = brw_OR(p, addr, surface, 0); | set_descriptor_control_bits(inst, ...); | inst = brw_SEND(p, dst, payload); | set_indirect_send_descriptor(inst, addr); | } This patch abstracts out this frequently recurring pattern so we can now write: | inst = brw_send_indirect_message(p, sfid, dst, payload, surface) | set_descriptor_control_bits(inst, ...); without worrying about handling the immediate and indirect surface index cases explicitly. v2: Rebase.
