# Usage: cd $(builddir)/mpn

#        $(srcdir)/x86/t-zdisp.sh

#

# 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).
