* glsl: Strip arrayness from ir_type_dereference_variable tooIan Romanick2014-09-261-1/+1
| | | | | | | | | | | | If the thing being dereferenced is a record or an array of records, it should be treated as row-major. The ir_type_derference_record path already does this, and I think I intended to do the same for this path in b17a4d5d.

* glsl: Make sure row-major array-of-structure get correct layoutIan Romanick2014-09-261-1/+8
| | | | | | | | | | | Whether or not the field is row-major (because it might be a bvec2 or something) does not affect the array itself. We need to know whether an array element in its entirety is row-major.

* glsl: Make sure fields after small structs have correct paddingIan Romanick2014-09-261-0/+22
| | | | | | | | | | | Previously the linker would correctly calculate the layout, but the lower_ubo_reference pass would not apply correct alignment to fields following small (less than 16-byte) nested structures.

* glsl: Do not add extra padding to structuresIan Romanick2014-08-041-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This code was attemping to align the base of the structure to the required alignment of the structure. However, it had two problems: 1. It was aligning the target structure member, not the base of the structure. 2. It was calculating the alignment based on the members previous to the target member instead of all the members of the structure.

* glsl: Fix lack of i2u in lower_ubo_reference.Kenneth Graunke2014-04-081-3/+7
| | | | | | | | | | | | | | | | | ir_binop_ubo_load takes unsigned integer operands. However, the array index used to compute these offsets may be a signed integer. (For example, see Piglit's spec/glsl-1.40/uniform_buffer/fs-bvec-array). For some reason, we were missing an ir_binop_i2u cast, and ir_validator was failing to catch that. Without this change, ir_builder's type inference code broke for me when writing a new optimization pass.
