// DefineFunctions.java — headless: disassemble + create a function at each address listed in
|
|
// ~/bfm-decomp/.run/<prog>_funcs.txt (one 0xADDR per line). Raw-binary auto-analysis (no entry
|
|
// points) finds only the reachable subset of functions; splat's linear sweep finds them all, so
|
|
// this seeds the Ghidra program with splat's VALIDATED boundaries — mechanical, NOT manual RE.
|
|
// Used in Phase 10 to complete the `resident` program (23 auto-found -> all 143). analyzeHeadless
|
|
// commits + saves on a clean exit (run WITHOUT -readOnly).
