Detailed Description

Options to control the LLVM lowering.

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

Definition at line 30 of file LoweringOptions.h.

Member Enumeration Documentation

◆ AllocLowering

enum mlir::LowerToLLVMOptions::AllocLowering

strong

Enumerator

Malloc

Use malloc for heap allocations.

AlignedAlloc

Use aligned_alloc for heap allocations.

None

Do not lower heap allocations.

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

Definition at line 37 of file LoweringOptions.h.
