Adds two integers, performs an overflow check, and pushes the result onto the evaluation stack.

The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
Format | Assembly Format | Description |
---|---|---|
D6 | add.ovf | Adds two signed integer values with an overflow check. |
The stack transitional behavior, in sequential order, is:
value1
is pushed onto the stack.value2
is pushed onto the stack.value2
andvalue1
are popped from the stack;value1
is added tovalue2
with a check for overflow.The result is pushed onto the stack.
OverflowException is thrown if the result is not represented in the result type.
You can perform this operation on signed integers. For floating-point values, use Add.
The acceptable operand types and their corresponding result data type are listed in the table below. If there is no entry for a particular type combination (for example, int32
and float
; int32
and int64
), it is an invalid Microsoft Intermediate Language (MSIL) instruction and generates an error.
