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