# 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).
