+# Check R_MIPS_GPREL32 relocation calculation if input file conatins
+# non-zero GP0 value in the .reginfo section.
+# FIXME: The only way to get an object file with non-zero GP0 value
+# is to link multiple object files with GOT relocations using '-r'
+# option. LLD does not calculate and generate GP0 correctly so we
+# use a binary input in this test. The input object file is a result
+# of linking two object files with R_MIPS_GPREL32 relocations.
