Consider the test:

$ cat test.cpp
#include <stdio.h>

int main(void)
{
    try {
        throw 1;
    }
    catch(int x) {
        printf("%d\n", x);
    }
    return 0;
}

Exception handling-related debug info is not emmited in clang
(DW_TAG_try_block, DW_TAG_catch_block). Bitcode file produced by clang is
attached.

Compilation line: clang -S  -O0 -g  test.cpp -emit-llvm -o test.bc
