# Enhanced Makefile for ISO 26262 test suite
# Common usage:
#   make              # build (with optional sanitizers via SAN=...)
#   make test         # run the tests
#   make clean        # remove binaries/objects
#   make coverage     # build with gcov coverage and generate .gcov files
#   make asan         # convenient Address/UBSan build
#   make zip          # create a zip of source + Makefile
#
# You can tune constants at compile-time, e.g.:
#   make CPPFLAGS="-DFUZZ_ITERS=5000 -DDEADLINE_MS=10"
