----------------
The location maybe if the diagnostic's source is located in the scratch buffer.
Likely for macro expansions where token pasting is involved. Another case would
be errors on the command line.
I'm not entirely sure how the SARIF spec would handle this case, it might
require an extension.
A few ways that might work could be:
Using the [[
https://docs.oasis-open.org/sarif/sarif/v2.0/csprd02/sarif-v2.0-csprd02.html#_Toc10127692
| logicalLocations ]] property to specify ([[
https://docs.oasis-open.org/sarif/sarif/v2.0/csprd02/sarif-v2.0-csprd02.html#_Toc10127910
| logicalLocation object ]]), this might need an extension for kind: "macro",
another case that might need extension is diagnostics about invalid command
line flags which are also diagnostics without a valid
The parentIndex for these logical locations could be set to the physical
location that produced them.
I think this definitely warrants some discussion since the spec doesn't provide
a clear way to express these cases.
