Structured byte- and relocation-level diff of a data symbol, target vs the decompiled build. objdiff's normal output diffs code; --include-data handles data: vtables, RTTI, pointer/jump tables, string pools, and static initializers.
Run the data diff against a data symbol with the command bin/objdiff-cli diff -p . -u <unit> "<symbol>" -f json-pretty --include-data

To find data symbol divergences, compare the target symbol against the decompiled build using objdiff with the --include-data flag to reveal byte- and relocation-level mismatches in vtables, RTTI, and string pools.
Yes, you can diff vtables and RTTI structures slot by slot by running a structured data symbol comparison to pinpoint exact layout mismatches between the target binary and the decompiled build.
The best way to validate static initializers during decompilation is to inspect byte- and relocation-level divergences in the data symbol using a structured JSON diff to validate data layout accuracy.
Yes, objdiff works with data symbols below 100% by comparing the target against the decompiled build to expose remaining byte-level divergences in pointer tables and string pools.
Get structured JSON output for binary data analysis by running the diff command with the -f json-pretty flag, which reads data_diff.relocations and data_diff.segments to pinpoint exact mismatches.
Your decompiled data layout may not match due to byte- and relocation-level divergences in static initializers or vtables, which you can identify by comparing the target symbol against the decompiled build.
