Ping #4: [PATCH] PR 99293: Optimize splat of a V2DF/V2DI extract with constant element

This patch seems to have been over looked. https://gcc.gnu.org/pipermail/gcc-patches/2024-September/663101.html I ran a set of spec 2017 benchmarks with this patch applied and compared it to a run without the patch applied. There were no regressions, but 3 benchmarks had slight improvement in ru

[PATCH] PR 99293: Optimize splat of a V2DF/V2DI extract with constant element

This is an old patch that I first wrote in 2021, and in the press of other work, the patch got lost. We had optimizations for splat of a vector extract for the other vector types, but we missed having one for V2DI and V2DF. This patch adds a combiner insn to do this optimization. In looking at t
