--- Comment #6 from Uroš Bizjak <ubizjak at gmail dot com> --- Created attachment 51879 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=51879&action=edit Improve HI/HFmode scalar insert The attached patch further improves HFmode -> SFmode conversion. HFmode values are passed in XMM registers, but PINSRW insn inserts only from memory or GPR. The patch introduces *vec_set<V8_128:mode>_0 insn pattern that also adds PBLENDW instruction that handles insert to element 0 from XMM source.
