linux32/steamclient.so is the 32-bit build games load via ~/.steam/sdk32. tools/decompile_batch.sh batches many binaries per Ghidra JVM for the Steam runtimes, mirroring their paths under decomp/runtime/. Co-Authored-By: Claude Opus 5.5 <[email protected]>

# Batch-decompile many binaries listed in a file (paths under client/), several
|
|
# per Ghidra JVM and several JVMs in parallel. Output mirrors the path under
|
|
# client/, e.g. client/runtime/x/lib/libc.so.6 -> decomp/runtime/x/lib/libc.so.6/.
|
|
# Ghidra databases are not kept (-readOnly), and binaries whose output already
|
|
# exists are skipped, so re-running resumes. Chunks that die (e.g. OOM) are
|
|
# retried one binary per JVM at the end.
|
|
# Usage: tools/decompile_batch.sh <list-file>
|
|
# Knobs: CHUNK (binaries per JVM, 40), PARALLEL (JVMs at once, 4), plus the
|
|
# per-JVM WORKERS / GHIDRA_HEADLESS_MAXMEM / MEMLIMIT from ghidra-env.sh.
