# # Two bugs make its output unusable:                                      #
# #  1. It passes FILE virtual addresses to Ghidra, which loads these       #
# #     binaries at image base 0x100000. Every address is 0x100000 too low, #
# #     so the decompiled "functions" are the wrong ones.                   #
# #  2. `-analysisTimeoutPerFile 0` does not mean "no timeout" in this      #
# #     Ghidra build: it aborts auto-analysis immediately, producing an     #
# #     analysed-looking project with no analysis at all.                   #
# #                                                                         #

# 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>
