Three reversing capabilities on the win32 surface plus a pure sig-gen handler:
- vmie_win32_functions enumerates a module's functions from the exception
directory (.pdata RUNTIME_FUNCTION), folding unwind chain continuations into
their primary - authoritative non-leaf boundaries, not prologue heuristics.
- vmie_win32_exports resolves the export table to {name, rva, ordinal,
forwarded}: named functions with no PDB or network. vmie_win32_pdb_ref pulls
the CodeView/RSDS {guid, age, pdb} from the debug directory - the symbol-server
key for any module (full PDB parsing stays out of scope).
- sig_generate (siggen.h) builds a unique masked signature for a code span,
wildcarding the rel/RIP-relative displacement bytes the x86 decoder locates and
growing until it matches the scope exactly once - the dual of sigscan.
The decoder now also reports disp_off/disp_len so a caller can mask the floating
bytes. The MZ/PE walk gains one shared data-directory accessor and one shared
CodeView/RSDS parser; the kernel bootstrap is moved onto both, removing its
private copies - one PE parser in the tree.
