Hi all,
This patch adds support for the vrint builtins. It also gathers the unspec
definitions in the various .md files in one file: unspecs.md.
A new iterator is defined that iterates over some new unspecs, in a similar
way to the scalar vrint implementation.
No regressions on arm-none-eabi.
Ok for trunk?
Thanks,
Kyrill
