File containing the variable definition

If the attached .ll files are compiled and linked with

llc -O1 tls_reloc.ll -filetype=obj
llc -O1 tls_reloc_main.ll -filetype=obj
gcc tls_reloc.o tls_reloc_main.o

then the linker shows the error message

/usr/bin/ld: nextIdx: TLS definition in tls_reloc_main.o section .tbss
mismatches non-TLS reference in tls_reloc.o
tls_reloc_main.o: could not read symbols: Bad value
