Tested as follows:

$ out/Debug/gm --config gpudebug --writePath tmp --verbose --match xfermodes2
--writeJsonSummaryPath tmp/out.json
Non-default runtime configuration options:
GM: These configs will be run: gpudebug
GM: writing to tmp
GM: drawing... xfermodes2 [455 475]
GM: Ran 1 GMs
GM: ... over  1 configs ["gpudebug"]
GM: ...  and  7 modes   ["pipe", "pipe cross-process", "pipe cross-process,
shared address", "replay", "rtree", "serialize", "tilegrid"]
GM: ... so there should be a total of 8 tests.
GM: Ran 8 tests: NoGpuContext=0 IntentionallySkipped=1 RenderModeMismatch=0
ExpectationsMismatch=0 MissingExpectations=0 WritingReferenceImage=0
GM: [*] 0 NoGpuContext:
