From 1a6c0efa116e7427e3ee5f24db2000e3edb66047 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 3 Sep 2013 16:55:37 -0700 Subject: glsl: Expose IR builder support for arbitrary swizzling. IR builder already offers a lot of swizzling functions, such as swizzle_xxxx, swizzle_z, or swizzle_for_size. The swizzle_xxxx style is convenient if you statically know which components you want. swizzle_for_size is great if you want to select the first few components. However, if you want to select components based on, say, a loop counter, none of those are sufficient. IR builder actually already had support for arbitrary swizzling, but didn't expose it. This patch exposes that API.
