Anders Fugmann b4706a3152 kotlin extractor: fold unaryMinus(IrConst) into a signed literal in K2
In K2 mode the frontend emits `-123L` as IrCall(unaryMinus, IrConst(123L))
rather than IrConst(-123L) as in K1. Queries that search for negative numeric
literals therefore need to match both a UnaryMinusExpr wrapping a literal and a
plain literal, depending on language mode.

Fix: when extractCallExpression encounters an isNumericFunction(unaryMinus) call
whose dispatchReceiver is already an IrConst, fold the negation into the constant
before extracting. The resulting literal node is identical to what K1 emits.

Location: extend the span one character to the left to cover the `-` sign.
In K2 the IrCall's startOffset equals the receiver's startOffset, so we recover
the minus by subtracting one from the receiver offset.

K1 is unaffected: the K1 frontend folds the sign into the constant before IR
generation, so this new branch never triggers when compiling with -language 1.9.

Expected output changes:
- test-kotlin2/library-tests/literals/literals.expected: negative long, float and
  double literals now appear as plain typed literals instead of as UnaryMinus nodes.
  The file is now byte-identical to test-kotlin1/library-tests/literals/literals.expected.

CodeQL

This open source repository contains the standard CodeQL libraries and queries that power GitHub Advanced Security and the other application security products that GitHub makes available to its customers worldwide.

How do I learn CodeQL and run queries?

There is extensive documentation about the CodeQL language, writing CodeQL using the CodeQL extension for Visual Studio Code and using the CodeQL CLI.

Contributing

We welcome contributions to our standard library and standard checks. Do you have an idea for a new check, or how to improve an existing query? Then please go ahead and open a pull request! Before you do, though, please take the time to read our contributing guidelines. You can also consult our style guides to learn how to format your code for consistency and clarity, how to write query metadata, and how to write query help documentation for your query.

For information on contributing to CodeQL documentation, see the "contributing guide" for docs.

License

The CodeQL CLI (including the CodeQL engine) is hosted in a different repository and is licensed separately. If you'd like to use the CodeQL CLI to analyze closed-source code, you will need a separate commercial license; please contact us for further help.

Visual Studio Code integration

If you use Visual Studio Code to work in this repository, there are a few integration features to make development easier.

CodeQL for Visual Studio Code

You can install the CodeQL for Visual Studio Code extension to get syntax highlighting, IntelliSense, and code navigation for the QL language, as well as unit test support for testing CodeQL libraries and queries.

Tasks

The .vscode/tasks.json file defines custom tasks specific to working in this repository. To invoke one of these tasks, select the Terminal | Run Task... menu option, and then select the desired task from the dropdown. You can also invoke the Tasks: Run Task command from the command palette.
