llvm dev - Feb 2020 - Preserving the type of structure

Hello,

LLVM IR flattens out the structure with one integer element to i32. Is
there any way to disable this? I want to preserve the type information of
the structure. I tried compiling the program with O0, it maintains the type
for most of the instructions but for all.

Regards,
Sangeeta

No - if you really want this sort of information you'd likely find it in
the debug info https://llvm.org/docs/SourceLevelDebugging.html or maybe
TBAA data.

Hi David,

Thanks for the response. I was wondering if you have any concrete steps to
get this information from TBAA data?
If you can point me towards some source or example then it would be really
helpful.
