1Title: Test multilib
2
3Description:
4
5Some architectures support different ISA variants, each backed a different
6multilib in a same compiler. Selecting wrong multilib may have adverse
7effects on performance, or sometime produce broken executables altogether
8(for example, ARM Cortex-M requires thumb2 multilib and will be broken with
9default ("arm") multilib or "thumb" multlib). This app is a smoke-test
10for selecting non-wrong multilib - it uses operation(s) which guaranteedly
11will call support routine(s) in libgcc and checks for expected result.

13Sample failure output ("thumb" used on Cortex-M instead of "thumb2"):
