New Revision: 272476
URL: https://svnweb.freebsd.org/changeset/base/272476
Log:
Allow vld and vst instructions to use the canonical form from ARM ARM when
including an alignment. Previously binutils would only allow instructions
in the form "vld1.64 {d0, d1}, [r0, :128]" where the final comma should
not be there, instead the above instruction should be
"vld1.64 {d0, d1}, [r0:128]".
This change duplicates the alignment code from within the function to
handle this case.
