Lu <hjl.tools at gmail dot com> --- We can extend STV pass to 64-bit mode to convert load and store of 128-bit ntegers to 128-bit SSE load and store, which is implemented on hjl/pr70155/master branch. As a follow-on optimization, we can add TImode bitwise patterns to use SSE for TImode bitwise operation.
