[llvm-dev] Structure transformations (splitting/peeling, field reordering) in LLVM

[chuanqi.xcq via llvm-dev]

Hi,

   AFAIK, there is SROA pass in LLVM to split structure. But I don't remember there are pass to reorder fields.

Thanks,
Chuanqi

Subject:[llvm-dev] Structure transformations (splitting/peeling, field reordering) in LLVM

Hello! 
I want to implement data layout optimizations, such as structure splitting/peeling, field reordering, etc. I know that such optimizations have not been implemented in LLVM (despite several research works in this field). But maybe somebody knows, whether at least transformations themselves (I mean splitting/peeling/reordering) are implemented in LLVM? I feel that some time ago I saw somewhere these transformations were implemented, maybe in some experimental part of LLVM, but now I can't find it despite my best efforts.
