# Written by B. Watson (urchlay@slackware.uk)
# Licensed under the WTFPL. See http://www.wtfpl.net/txt/copying/ for details.
# 20251214 bkw: updated for v4.32c. This isn't the latest version, but
# it's the latest version that will build on 15.0 *with* afl-clang-lto
# support. >= 4.33c would need a newer clang. It wouldn't be utterly
# useless without afl-clang-lto, but it's upstream's recommended way
# to build fuzzable binaries, so I don't want to drop it.

# "make all" doesn't include qemu_mode (which gets built separately,
# below). The other modes aren't built because they're a lot of effort
# to build for not much gain:
# coresight_mode: ARM64-only. Beyond the scope of this SBo build.
# frida_mode: New and missing a lot of features. Also a PITA to build.
# nyx_mode: Written in Rust. Too fast-moving of a target for me, sorry.
# unicorn_mode: Looks interesting, but I don't need it, do you?
# Anyone who wants to is welcome to submit SlackBuilds for the other
# modes, though it'll take some care to keep them from conflicting
# with this one: your script will have to build the main aflplusplus
# stuff (make all), because the "modes" require it to be built first,
# but your package should only install the mode-specific stuff (so you
# can't just use "make install").
