  32 # Usage: cd $(builddir)/mpn
  33 #        $(srcdir)/x86/t-zdisp.sh
  34 #
  35 # Run the Zdisp() macro instructions through the assembler to check
  36 # the encodings used.  Mismatches are printed, no output means all ok.
  37 #
  38 # This program is only meant for use during development.  It can be
  39 # run in the mpn build directory of any x86 configuration.
  40 #
  41 # For this test the assembler needs to generate byte sized 0
  42 # displacements when given something like 0(%eax).  Recent versions of
  43 # gas are suitable (eg. 2.9.x or 2.10.x).
