1# REQUIRES: mips2## Check that we ignore R_MIPS_JALR relocations agains non-function symbols.3## Older versions of clang were erroneously generating them for function pointers4## loaded from any table (not just the GOT) as well as against TLS function5## pointers (when using the local-dynamic model), so we need to ignore these6## relocations to avoid generating binaries that crash when executed.7 8# RUN: llvm-mc -filetype=obj -triple=mips64-unknown-linux %s -o %t.o9## Link in another object file with a .bss as a regression test:10## Previously LLD asserted when skipping over .bss sections when determining the11## location for a warning/error message.
