The test currently expects to be run in a directory named 'clang' but
that's not valid for our release tarballs. We don't actually care what
base directory the test is run from, so this removes the path component
entirely.
Refactor StaticAnalyzer to use clang::SarifDocumentWriter for
serializing sarif diagnostics.
Uses clang::SarifDocumentWriter to generate SARIF output in the
StaticAnalyzer.
Various bugfixes are also made to clang::SarifDocumentWriter.
Summary of changes:
clang/lib/Basic/Sarif.cpp:
* Fix bug in adjustColumnPos introduced from prev move, it now uses
FullSourceLoc::getDecomposedExpansionLoc which provides the correct
location (in the presence of macros) instead of
FullSourceLoc::getDecomposedLoc.
* Fix createTextRegion so that it handles caret ranges correctly,
this should bring it to parity with the previous implementation.
clang/test/Analysis/diagnostics/Inputs/expected-sarif:
* Update the schema URL to the offical website
* Add the emitted defaultConfiguration sections to all rules
* Annotate results with the "level" property
clang/lib/StaticAnalyzer/Core/SarifDiagnostics.cpp:
* Update SarifDiagnostics class to hold a clang::SarifDocumentWriter
that it uses to convert diagnostics to SARIF.
The rule IDs are not stable, so this uses a regex for the rule ids
instead of concrete values. It also moves the CHECK lines below the
code so that it's easier to modify the test in the future. It also
breaks the CHECK lines into multiple lines to improve the performance
of the test and aid in debugging failures. Finally, it adds a comment
to the top of the test explaining that things are still rather fragile.
Enables Clang to emit diagnostics in SARIF format when
`-fdiagnostics-format=sarif`. Adds a new DiagnosticConsumer named
SARIFDiagnosticPrinter and a new DiagnosticRenderer named SARIFDiagnostic
to constuct and emit a SARIF object containing the run's basic diagnostic info.
