Subject: [Bug rtl-optimization/112525] fail to eliminate unused store
Date: Tue, 14 Nov 2023 07:01:17 +0000	[thread overview]
Message-ID: <bug-112525-4-0zkeF7YExf@http.gcc.gnu.org/bugzilla/> (raw)

--- Comment #3 from Jiu Fu Guo <guojiufu at gcc dot gnu.org> ---
One possible method is fixing DSE to let is able to remove those 'store's.
(but need to take care of the case that is using 'arg_pointer' to pass
parameters.)


Another method: there is a patch
https://gcc.gnu.org/pipermail/gcc-patches/2023-October/634500.html which
introduces lighter-expander-sra (this patch is only for struct parameter now).
We may enhance this patch to avoid storing the unused parameters.
