Bug ID: 115662
Summary: Feature request: support for linking SARIF files
together
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Keywords: SARIF
Severity: enhancement
Priority: P3
Component: analyzer
Assignee: dmalcolm at gcc dot gnu.org
Reporter: egallager at gcc dot gnu.org
Target Milestone: ---
I brought this up on IRC previously, but since I can't remember when, I'll
rewrite it the best I can here:
Basically, there are cases where one might want to combine a bunch of SARIF
files together into a single one. Previously I thought it might be possible to
simply `cat` them together, but apparently it involves something a little bit
more complex, like json-ld: https://json-ld.org/
So basically, my proposal is this: if a build has taken place where
-fdiagnostics-format=sarif-file has been used for some of the individual
compilations, and then the gcc driver is invoked for the linking step with that
same flag, and it can still find all the SARIF files, it should then invoke
json-ld (or possibly our own implementation) to link all of the SARIF files
together into a new one. This would be helpful for applications that might want
to just read a single SARIF file at a time.
