2## Check that we ignore R_MIPS_JALR relocations agains non-function symbols.
3## Older versions of clang were erroneously generating them for function pointers
4## loaded from any table (not just the GOT) as well as against TLS function
5## pointers (when using the local-dynamic model), so we need to ignore these
6## relocations to avoid generating binaries that crash when executed.

12## section before the actual %t.o we can reproduce this case.
