+#
+# Run the Zdisp() macro instructions through the assembler to check
+# the encodings used.  Mismatches are printed, no output means all ok.
+#
+# This program is only meant for use during development.  It can be
+# run in the mpn build directory of any x86 configuration.
+#
+# For this test the assembler needs to generate byte sized 0
+# displacements when given something like 0(%eax).  Recent versions of
+# gas are suitable (eg. 2.9.x or 2.10.x).
