-ddump-json doesn't interact as expected with -ddump-to-file
Usually with dump flags, if you set ddump-to-file then the dumped file will be outputted in the current directory if -dumpdir or -ddump-file-prefix is not set. This doesn't work with -ddump-json, if you do not specify
-ddump-file-prefix then the output is always on stdout.
Clearly stated, here are the two problems which I think have the same solution.
-
-ddump-to-file -ddump-jsonshould output a file in the currect directory. -
-ddump-to-file -ddump-jsondoes not respect-dumpdir
It seems that a stale set of DynFlags is used to direct the output of -ddump-json. The relevant function is DynFlags.jsonLogFinaliser.
