How to optimize out the duplicated memory load instructions?
Hi Johannes,
Thanks for your help. I tried with something like below and nothing
changes. Maybe I am doing something wrong?
246001 check_exce_succ59: ; preds =
%check_exce_succ40
**246002 %mem_base60 = load i8*, i8** %mem_base_addr_ptr, align 8,
!alias.scope !3
246003 %offset161 = add i32 %call56, 4
246004 %12 = sext i32 %offset161 to i64
246005 %maddr62 = getelementptr inbounds i8, i8* %mem_base60, i64 %12
246006 %data_ptr63 = bitcast i8* %maddr62 to i64*
**24600...

How to optimize out the duplicated memory load instructions?
...nstruct llvm optimization pass to optimize out
the %mem_base66 and make the subsequent code reuse the %mem_base60? I
tried with metadata 'alias.scope' and 'noalias' and it doesn't help. Thanks
for any advice.
