Here's a patch for gas in binutils that makes it use libdiagnostics
(with some nasty hardcoded paths to specific places on my hard drive
to make it easier to develop the API).
For now this hardcodes adding two sinks: a text sink on stderr, and
also a SARIF output to stderr (which happens after all regular output).
For example, without this patch:
gas testsuite/gas/all/warn-1.s
emits:
VVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVVV

which I see:
- drops the leading "Assembler messages" warning,
- changes the capitalization of the "Warning" -> "warning" etc
- quotes the pertinent line in the .s file
All of the locations are just lines; does gas do column numbers at all?
(or ranges?)
For reference, running the above SARIF through "python -m json.tool" to
prettyify it gives:
