Hello,
the ARM Optimizing C/C++ Compiler v18.1.0.LTS maual states in section 5.7:
Using the --exceptions option causes the compiler to insert exception handling code. This code will
increase the size of the program, but EABI does not increase the code size much, and has a minimal
execution time cost if exceptions are never thrown. It slightly increases the data size for the exception-
handling tables.
Please, what kind of data is the term "exception-handling tables" referring to?
Is it related to stack unwinding tables?
Can it be assumed that no stack unwinding tables are generated if the --exceptions option is not used?
Thank you in advance.
Hi Carlos,
Can you please refer below thread once:
The exception handling tables are specially-encoded information about the functions and objects in those functions that need to be considered when propagating C++ exceptions. They are read by special functions in the RTS and are not meant for the user to read directly. For documentation, see infocenter.arm.com/.../IHI0038B_ehabi.pdf
