# 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).
