Bootstrapped and regtested on s390x-redhat-linux. Ok for master?
The destination register is only partially overwritten, so + should be
used instead of =.
gcc/ChangeLog:
2021-01-08 Ilya Leoshkevich <i...@linux.ibm.com>
* config/s390/vector.md (*tf_to_fprx2_0): Rename from
*mov_tf_to_fprx2_0 for consistency, fix constraint.
(*tf_to_fprx2_1): Rename from *mov_tf_to_fprx2_1 for
consistency, fix constraint.
