Description

When the ctftest-convert-no-dwarf.ksh and ctftest-convert-non-c.ksh tests generate C files, they have functions that never return anything. While gcc seems to ignore that by default, clang emits warnings about that. We should just fix the tests to have a dummy return value.

I tested this by running the CTF test suite against a number of different compilers with both -gdwarf-2 and -gdwarf-4 (when supported). The compilers were:

  • gcc 4.4.4
  • gcc 7.4.0
  • gcc 7.5.0
  • gcc 8.3.0
  • gcc 9.3.0
  • gcc 10.2.0
  • clang 8.0.1
  • clang 9.0.1
  • clang 10.0.1
  • clang 11.0.0
