Convert to an int16 (on the stack as int32) and throw an exception on overflow. Base instruction 0x83 conv.ovf.i2.un: Convert unsigned to an int16 (on the stack as int32) and throw an exception on overflow. Base instruction 0xB7 conv.ovf.i4: Convert to an int32 (on the stack as int32) and throw an exception on overflow. Base instruction 0x84
The location (in memory) of the code for handling an exception need not be located within (or even near) the region of memory where the rest of the function's code is stored. So if an exception is thrown then a performance hit – roughly comparable to a function call [24] – may occur if the necessary exception handling code needs to be ...
In this C# example, all exceptions are caught regardless of type, and a new generic exception is thrown, keeping only the message of the original exception. The original stacktrace is lost, along with the type of the original exception, any exception for which the original exception was a wrapper, and any other information captured in the ...
Exceptions are defined by different layers of a computer system, and the typical layers are CPU-defined interrupts, operating system (OS)-defined signals, programming language-defined exceptions. Each layer requires different ways of exception handling although they may be interrelated, e.g. a CPU interrupt could be turned into an OS signal.
C does not provide direct support to exception handling: it is the programmer's responsibility to prevent errors in the first place and test return values from the functions.
Exception safety is the state of code working correctly when exceptions are thrown. [1] To aid in ensuring exception safety, C++ standard library developers have devised a set of exception safety levels , contractual guarantees of the behavior of a data structure's operations with regards to exceptions.

Processor exceptions generated by the CPU have fixed mapping to the first up to 32 interrupt vectors. [1] While 32 vectors (0x00-0x1f) are officially reserved (and many of them are used in newer processors), the original 8086 used only the first five (0-4) interrupt vectors and the IBM PC IDT layout did not respect the reserved range.
