it doesn't help. `jmp .L2` skips catch block :)
main:
pushq %rbx
movl $_Z13signalHandleri, %esi
movl $11, %edi
call signal
movl $0, 0
jmp .L2
.L8:
cmpq $1, %rdx
je .L3
movq %rax, %rdi
call _Unwind_Resume
.L3:
movq %rax, %rdi
call __cxa_begin_catch
movl (%rax), %eax
call __cxa_end_catch
jmp .L2
.L7:
movq %rax, %rbx
.L4:
call __cxa_end_catch
movq %rbx, %rdi
call _Unwind_Resume
.L2:
movl $0, %eax
popq %rbx
ret
