protoc dependency files, at least for C++ outputs, uses the form of: a/b.c \ a/b.h: <dep1> <dep2>... Ninja will fail the command when it parses a dep file and there's more than one output file (even though it doesn't care what the output file name is). So this tool will parse the original file, and output a version with only a single output file. Bug: 67329638 Test: NINJA_ARGS="-t deps ...pb.c" m Test: NINJA_ARGS="-t deps ...srcjar" m Test: NINJA_ARGS="-t deps ...srcszip" m Test: Run dep_fixer across all of taimen's dep files, no failures. Test: Run dep_fixer against the processed files, no changes. Test: Run androidmk across all of our Android.mk files, inspect the diffs Change-Id: I4263b7d5faea37285afa6b24dedf5964aa7d19dc
