Hi TI-Experts,

 I am using TI Clang v1.3.0.LTS to compile my C code, and I try unwind stack by .ARM.exidx section, but why the  .ARM.exidx section are empty? How to enable it ?

Thanks

    The section .ARM.exidx is related to C++ exceptions.  At present, the tiarmclang compiler does not support C++ exceptions.  That is why the ARM.exidx section is empty.  This feature will be added in a future release.  The entry EXT_EP-10343 is already filed for this issue.

    Thanks and regards,
