Subject: Fix protobuf backend build dependencies
X-Git-Tag: yosys-0.10~7^2
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c25122e33993b6634280bd1babef4b329c112921;p=yosys.git

Fix protobuf backend build dependencies

backends/protobuf/protobuf.cc depends on the source and header files
generated by protoc, but this dependency wasn't explicitly declared. Add
a rule to the Makefile to fix intermittent build failures when the
protobuf header/source file isn't built before protobuf.cc.
