|
* /brief processes a node from the export trie, and its children.
|
|
*
|
|
* To my knowledge there is no documentation of the encoded format of this data
|
|
* other than in the heads of the Apple linker engineers. To that end hopefully
|
|
* this comment and the implementation below can serve to light the way for
|
|
* anyone crazy enough to come down this path in the future.
|
|
*
|
|
* This function reads and preserves the trie structure of the export trie. To
|
|
* my knowledge there is no code anywhere else that reads the data and preserves
|
|
* the Trie. LD64 (sources available at opensource.apple.com) has a similar
|
|
* implementation that parses the export trie into a vector. That code as well
|
|
* as LLVM's libObject MachO implementation were the basis for this.
|
|
*
|
|
* The export trie is an encoded trie. The node serialization is a bit awkward.
|
|
* The below pseudo-code is the best description I've come up with for it.
|
|
*
|
|
* struct SerializedNode {
|
|
* ULEB128 TerminalSize;
|
|
* struct TerminalData { <-- This is only present if TerminalSize > 0
|
|
* ULEB128 Flags;
|
|
* ULEB128 Address; <-- Present if (! Flags & REEXPORT )
|
|
* ULEB128 Other; <-- Present if ( Flags & REEXPORT ||
|
|
* Flags & STUB_AND_RESOLVER )
|
|
* char[] ImportName; <-- Present if ( Flags & REEXPORT )
|
|
* }
|
|
* uint8_t ChildrenCount;
|
|
* Pair<char[], ULEB128> ChildNameOffsetPair[ChildrenCount];
|
|
* SerializedNode Children[ChildrenCount]
|
|
* }
|
|
*
|
|
* Terminal nodes are nodes that represent actual exports. They can appear
|
|
* anywhere in the tree other than at the root; they do not need to be leaf
|
|
* nodes. When reading the data out of the trie this routine reads it in-order,
|
|
* but it puts the child names and offsets directly into the child nodes. This
|
|
* results in looping over the children twice during serialization and
|
|
* de-serialization, but it makes the YAML representation more human readable.
|
|
*
|
|
* Below is an example of the graph from a "Hello World" executable:
|
|
*
|
|
* -------
|
|
* | '' |
|
|
* -------
|
|
* |
|
|
* -------
|
|
* | '_' |
|
|
* -------
|
|
* |
|
|
* |----------------------------------------|
|
|
* | |
|
|
* ------------------------ ---------------------
|
|
* | '_mh_execute_header' | | 'main' |
|
|
* | Flags: 0x00000000 | | Flags: 0x00000000 |
|
|
* | Addr: 0x00000000 | | Addr: 0x00001160 |
|
|
* ------------------------ ---------------------
|
|
*
|
|
* This graph represents the trie for the exports "__mh_execute_header" and
|
|
* "_main". In the graph only the "_main" and "__mh_execute_header" nodes are
|
|
* terminal.
