Subject: [Bug tree-optimization/114908] fails to optimize avx2 in-register permute written with std::experimental::simd
Date: Tue, 07 May 2024 03:09:16 +0000	[thread overview]
Message-ID: <bug-114908-4-EWMi1F6naE@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #8 from Imple Lee <lee.imple at gmail dot com> ---
I tried another way to permute the register.
Although GCC does generate simd instructions, the generated code is
sub-optimal.
I opened PR114966 for that.
