<div dir="auto">Hi,<br />
<br />
<span style="white-space:pre"> I think it’s a common issue for multi version for all ISAs</span><br />
<span style="white-space:pre"> if we want to implement it.</span><br />
<br />
<span style="white-space:pre"> I do not find any code to record the version of isa feature also,</span><br />
<span style="white-space:pre"> the llvm use the default version by hardcode just only by now :(</span><br />
<span style="white-space:pre"> Is it reasonable ?</span><br />
<br />
<span style="white-space:pre"> From gcc developer view, it records the version in gcc internal from</span><br />
<span style="white-space:pre"> command line of isa feature and deal with different purpose of multi versions. </span></div>

<div dir="ltr">Hello everyone. RVV 0.10 is now supported on the upstream LLVM RISC-V backend. However, because some RISC-V-based chip manufacturers chose RVV 0.71 version as the vector extension at the beginning, and a large number of chips that supported RVV 0.71 version are taped out. So can the community explore a way or framework to support different versions of RVV?<br />
Best wishes.<br /></div>
