  "message": "Make .d file analysis properly mark used module (.pcm) files.\n\nPreviously, we thought this wouldn\u0027t be necessary, as a change in .pcm would\nalways be accompanied by a corresponding change in a header. However, in the\ncurrent compile module this isn\u0027t true. Modules currently require all\ntransitive modules as inputs even though they might not use a single header\nfrom them. Thus, if a module //a depends on a module //b, any change to //b\u0027s\nheaders will currently require //a to be rebuilt unless those headers are\nactually included by //a. This leads to false positive cache results.\n\n--\nMOS_MIGRATED_REVID\u003d135134348\n",
