# REQUIRES: mips
# MIPS TLS variables that are marked as local by a version script were
# previously writing values to the GOT that caused runtime crashes. This
# was happending when linking jemalloc_tsd.c in FreeBSD libc. Check that
# we do the right thing now:
# RUN: llvm-mc -filetype=obj -triple=mips64-unknown-freebsd %s -o %t.o
# RUN: echo "{ global: foo; local: *; };" > %t.script
# RUN: echo "SECTIONS { \
# RUN: . = 0x10000; .text : { *(.text) } \
# RUN: . = 0x20000; .got : { *(.got) } \
# RUN: }" > %t.script1
# RUN: ld.lld --version-script %t.script -script %t.script1 -shared %t.o -o %t.so
# RUN: llvm-objdump --section=.got -s %t.so | FileCheck %s --check-prefix GOT
# RUN: llvm-readobj -r %t.so | FileCheck %s -check-prefix RELOCS
# GOT: Contents of section .got:
# GOT-NEXT: 20000 00000000 00000000 80000000 00000000
# GOT-NEXT: 20010 00000000 00000000 00000000 00000000
# GOT-NEXT: 20020 ffffffff ffff8000
# RELOCS: Section ({{.+}}) .rel.dyn {

# RELOCS-NEXT: }
