NoException Attribute

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = false)]
public class NoExceptionAttribute : Attribute
{
    public NoExceptionAttribute() { ... }
}

It forces compiler to disable Exception check

• After calling a function, Compiler checks if ECX is NULL or not. NoException Attribute disables this feature
• It is useful for non-Atomixilc build code. like C-Library and other stuffs.
• It is recommended to Add NoException Attribute where ever Assembly(false) is used.

Label Attribute

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false)]
public class LabelAttribute : Attribute
{
    public readonly string RefLabel;
    public LabelAttribute(string label) { ... }
}

• Assign an identifier to the Method function

• It does not change symbol name.
• Resolved internally by Compiler.

• Usage

[Label("Hello")]
internal static void Test() { ... }

// somewhere in assembly stub
new Call { DestinationRef = "Hello", IsLabel = true };

Plug Attribute

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false)]
public class LabelAttribute : Attribute
{
    public readonly string RefLabel;
    public LabelAttribute(string label) { ... } 
}

• To manipulate generated symbol name

• Basically It changes global symbol name for given method function.

• Example

• C# Code (without plug attribute)

internal static void Test() { ... }

• Output

System_Void_Test__:
    ; ...

• C# Code (with plug attribute)

[Plug("Hello")]
internal static void Test() { ... }

• Output

Hello:
    ; ...
