InlineAssemblyDialect

public enum InlineAssemblyDialect

Enumerates the dialects of inline assembly LLVM’s parsers can handle.

  • att

    The dialect of assembly created at Bell Labs by AT&T.

    AT&T syntax differs from Intel syntax in a number of ways. Notably:

    • The source operand is before the destination operand
    • Immediate operands are prefixed by a dollar-sign ($)
    • Register operands are preceded by a percent-sign (%)
    • The size of memory operands is determined from the last character of the the opcode name. Valid suffixes include b for “byte” (8-bit), w for “word” (16-bit), l for “long-word” (32-bit), and q for “quad-word” (64-bit) memory references

    Declaration

    Swift

    case att

  • The dialect of assembly created at Intel.

    Intel syntax differs from AT&T syntax in a number of ways. Notably:

    • The destination operand is before the source operand
    • Immediate and register operands have no prefix.
    • Memory operands are annotated with their sizes. Valid annotations include byte ptr (8-bit), word ptr (16-bit), dword ptr (32-bit) and qword ptr (64-bit).
