Module layout 

Struct layout computation for AIR types.

Reimplements LLVM’s StructLayout algorithm for computing field byte offsets, sizes, and alignment. Uses System V AMD64 ABI defaults which cover ~99% of x86-64 C/C++ code.

Functions

abi_alignment

Returns the ABI alignment in bytes for a type under System V AMD64 rules.

abi_alignment_with_ptr

Returns the ABI alignment in bytes for a type, using the specified pointer width.

align_up 🔒

Round value up to the next multiple of align.

alloc_size

Returns the allocation size in bytes for a type.

alloc_size_with_ptr

Returns the allocation size in bytes for a type, using the specified pointer width.

compute_struct_layout

Computes struct layout: field byte offsets and total size (including tail padding).

compute_struct_layout_with_ptr

Computes struct layout: field byte offsets and total size (including tail padding), using the specified pointer width.
