I don't know, maybe we can try to ask rvv-intrinsic-doc define so many tuple types and try to make them reduce the api && tuple types?
I am going to remove all FP16 vector to see whether we can reduce machine modes <= 256. I think it may be probably helping to fix that. juzhe.zh...@rivai.ai From: Jeff Law Date: 2023-04-11 04:36 To: Jakub Jelinek CC: juzhe.zhong; gcc-patches; kito.cheng; palmer; richard.sandiford; rguenther Subject: Re: [PATCH] machine_mode type size: Extend enum size from 8-bit to 16-bit On 4/10/23 09:18, Jakub Jelinek wrote: > On Mon, Apr 10, 2023 at 08:54:12AM -0600, Jeff Law wrote: >> This is likely going to be very controversial.

To put it another way. Why does RISC-V have so many more modes than AArch64. Jeff
