I think I used the wrong data structure :) I reproduced the problem you were having and then got tired of thinking about how to memmove elements. I rewrote the annotation code yesterday to use a linked list, which is much more natural. I just sent the patches. Attached is a patch you can squash into your series in order to make it work on top of my series. > However, once this is done, the build does assert() on some shaders that I > have; this is because it fails to understand some registers. I think that's a result of the disassembler not knowing how to disassemble sends/sendsc. Both Toni and Neil have written patches for that. I'll see if I can rebase them.
