◆ PostAllocationPasses
Post-allocation passes.
These passes are called on the graph after memory has been allocated and defined nodes have been assigned their final addresses, but before the context has been notified of these addresses. At this point externals have not been resolved, and symbol content has not yet been copied into working memory.
Notable use cases: Setting up data structures associated with addresses of defined symbols (e.g. a mapping of __dso_handle to JITDylib* for the JIT runtime) – using a PostAllocationPass for this ensures that the data structures are in-place before any query for resolved symbols can complete.

◆ PostFixupPasses
◆ PostPrunePasses
Post-prune passes.
These passes are called on the graph after dead stripping, but before memory is allocated or nodes assigned their final addresses.
Notable use cases: Building GOT, stub, and TLV symbols.

◆ PreFixupPasses
Pre-fixup passes.
These passes are called on the graph after memory has been allocated, content copied into working memory, and all nodes (including externals) have been assigned their final addresses, but before any fixups have been applied.
Notable use cases: Late link-time optimizations like GOT and stub elimination.

◆ PrePrunePasses
Pre-prune passes.
These passes are called on the graph after it is built, and before any symbols have been pruned. Graph nodes still have their original vmaddrs.
Notable use cases: Marking symbols live or should-discard.
