  "message": "gdb/dwarf: use gdb::unordered_set for seen_names\n\nDirect replacement of an htab with a gdb::unordered_set.\n\nUsing a large test program, I see a small but consistent performance\nimprovement.  The \"file\" command time goes on average from 7.88 to 7.73\nseconds (~2%).  To give a rough estimate of the scale of the test\nprogram, the 8 seen_names hash tables (one for each worker thread) had\nbetween 173846 and 866961 entries.\n\nChange-Id: I0157cbd04bb55338bb1fcefd2690aeef52fe3afe\nApproved-By: Tom Tromey \u003ctom@tromey.com\u003e\n",
