Class AsmIsUsed

An optional detector that highlights all the asm functions.

Why is it bad?

Using TVM Assembly is a potentially dangerous operation that requires additional attention from an auditor. This optional detector will highlight all its uses to assist in contract security audits.

Example

// Highlighted: the asm function use should be audited
asm fun getStorageFee(cells: Int, bits: Int, seconds: Int, is_masterchain: Bool): Int { GETSTORAGEFEE }

severity

severity: Severity = Severity.INFO

Gets the severity of the detector.

Accessors

id

  • get id(): string

  • Gets the short identifier of the detector, used in analyzer warnings.

    Returns string

    The unique identifier of the detector.

kind

shareImportedWarnings

  • get shareImportedWarnings(): WarningsBehavior

  • Defines the behavior of warnings generated by this detector when working with multiple projects within a single Tact configuration.

    Here are the available options:

    1. "union" Leave this value if you don't care about warnings generated in other projects.
    2. "intersect" If the warning is generated for some source location of the imported file, it should be generated by each of the projects. Example: Constants from an imported file should not be reported iff they are unused in all the projects, so you need "intersect".

    Returns WarningsBehavior

usesSouffle

  • get usesSouffle(): boolean

  • Checks whether this detector needs the Soufflé binary to be executed.

    Returns boolean
