Detailed Description

Options to control the LLVM lowering.

The struct is used to share lowering options between passes, patterns, and type converter.

Member Enumeration Documentation

◆ AllocLowering


Use malloc for for heap allocations.


Use aligned_alloc for heap allocations.


Do not lower heap allocations.

Users must provide their own patterns for AllocOp and DeallocOp lowering.

Member Data Documentation

◆ allocLowering

AllocLowering mlir::LowerToLLVMOptions::allocLowering = AllocLowering::Malloc

◆ dataLayout
