# ghidra_analyze.sh - import a library into a Ghidra project and run the full
# auto-analysis once. The project is kept, so later decompilations are cheap:
#
# scripts/ghidra_decompile_project.sh <hex-vaddr> [outfile]
#
# Full analysis of a ~70 MB library can take a long time; run it in the
# background and log to run/ghidra-analyze.log.
#
# Usage: scripts/ghidra_analyze.sh <binary>
# env: GHIDRA_HOME (default /snap/ghidra/current/ghidra)
# PROJECT_DIR (default ../run/ghidra-proj)
# PROJECT_NAME (default cuda-analysis)
