12:05 Triang3l: gerddie: What happens if the control flow exceeds the hardware stack space in SFN? SPIR-V requires a maximum depth of at least 1023, but I think that's much bigger than what the hardware can provide?
12:06 Triang3l: I'd imagine that would need a fallback from pred_set to pred_set_push and using GPRs instead of the stack for nesting on very deep levels, but I can't find any predicate pushing in the R600 code
12:08 Triang3l: or is that just a distant TODO for now?
12:10 Triang3l: also, can excess GPRs be spilled to the scratch already?
