# REQUIRES: mips
# Check addend adjustment in case of generating a relocatable object
# if some input files have non-zero GP0 value.
# We have to use GNU as and ld.bfd 2.28 to generate relocatable object
# files with non-zero GP0 value using the following command lines:
#
# as -mips32 -o test.o \
# && ld.bfd -m elf32btsmip -r test.o -o mips-gp0-non-zero.o
# as -mips64 -o test.o \
# && ld.bfd -m elf64btsmip -r test.o -o mips-n64-gp0-non-zero.o
