| [BACKEND] Add LLVM pre-processing pass to break struct types (#2285)
Add infrastructure to be able to add and test custom LLVM passes in the
backend. This will allow use to apply some low level optimizations and
cleanup on LLVM IR.
Add a first pass that breaks up phi of struct created by lowering to
LLVM. Those can often pessimise the optimizer as it would block
optimizations going through phi nodes. | 2 年前 |
