+# REQUIRES: mips

+# Conditions:
+# a) Object file contains microMIPS instructions.
+# b) There is a relocation refers arbitrary symbols and requires a PLT entry.
+# Check:
+# a) PLT contains a compressed entry.

+# FIXME (simon): Check the disassembler output when llvm-objdump starts
+#                to support microMIPS instruction encoding.
