From: Jason Ekstrand Date: Fri, 23 Mar 2018 01:48:01 +0000 (-0700) Subject: spirv/cfg: Make the builder fully capable for both walks X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=58799b6a5b3e281365bce91fac2e54903fbd2c41;p=mesa.git spirv/cfg: Make the builder fully capable for both walks We were only initializing vtn_builder::func for the pre-walk where we build the CFG. We were only initializing the nir_builder for the later walk through the instructions even though were were setting b->cursor for the pre-walk. Let's set both both places so that everything is consistent. This useful because we handle OpFunctionParameter in the pre-walk and we're going to need to be able to emit instructions.
