[cmake] Add dependency on llvm-dwarfdump to llvm-locstats

Authored by DavidSpickett on Dec 19 2019, 7:08 AM.



Though llvm-locstat is a "util" it requires llvm-dwarfdump
to be useful. So what happens now is that unless LLVM_BUILD_TOOLS
is ON llvm-locstats won't be part of the "all" target.

However given that it requires llvm-dwarfdump, this is less
confusing/build time consuming than suddenly having llvm-dwarfdump
build when all other tools are disabled.

Please make sure the tool name is llvm-locstats instead of llvm-covstat.

(This patch is follow up for the, where is the rest of the conversation).


Please describe, once again, why you decided to use the LLVM_BUILD_UTILS instead of the LLVM_BUILD_TOOLS here.

I was testing both and got confused along the way. LLVM_BUILD_TOOLS is what I intended.

Reasoning being that though llvm-locstats requires llvm-dwarfdump, it would be a bigger problem to start building llvm-dwarfdump when LLVM_BUILD_TOOLS is OFF, than it is to not build llvm-locstats when LLVM_BUILD_UTILS is ON.

(from the point of view of someone trying to trim their build time)
