...These operations that provide access to another thread's register storage pose a particular challenge to the compiler, particularly when combined with the use of predication for control flow. Consider the following example: // texture lookup that computes gradient of r0, last use of r0 r1 = texture2D(..., r0, ...) if (...) { // r0 used as temporary here r0 = ... r2 = r0 + ... } else { // only use of r1 r2 = r1 + ... } In this example, various optimizations might try to sink the texture2D operation into the else block, like so: if (...) { r0 = ... r2 = r0 + ... } else { r1 = te...

Why is this a regalloc problem? I assume in the example below the "r0" is somehow forced by the ABI? Because otherwise moving the texture2d operation into the branch wouldn't matter as long as we assign different registers to the two branches and use a technique like lib/Target/R600/SIFixSGPRLiveRanges.cpp. - Matthias > On May 13, 2015, at 6:00 PM, Philip Reames <listmail at philipreames.com> wrote: > > LGTM.

...ying logic triggered by it. Christoph, I spoke with Marek earlier on IRC, and he thought it was probably an issue in our ->blit routine. I agree that this makes sense, however that's the only piglit test that fails in tests/shaders (well, related to textures), and there are plenty of other texture2D-using tests. I looked at the mmt traces, and they seem pretty reasonable. What's unique about this test is that it uses a 0.01 value in the texture rather than the more common 1/-1. FWIW the failure looks like: $ bin/shader_runner tests/shaders/glsl-fs-lots-of-tex.shader_test -auto Probe colo...
