[LLVMdev] clang/g++ frontend: can __cxa_end_catch throw?
...' with termination in case of exception. clang++
always just calls __cxa_end_catch with 'call' instruction.
Which way is correct?
--- c.cpp ---
#include <stdio.h>

E();

void mythrowing2();
void mycatching(E *e);
void myfunc() {
try {

mythrowing1();
mythrowing2();
} catch (E *e) {
mycatching(e);
}
