X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7558b5da13685f701cbe7a9ca804e95e01e38e63;p=mesa.git compiler: Add a note about how num_ssbos works in the program info. These numbers are always confusing, and it's particularly so for this field where it has a different meaning in different info structs.
