# Some useful compiler options for internal tests:
# -DLUAI_ASSERT turns on all assertions inside Lua.
# -DHARDSTACKTESTS forces a reallocation of the stack at every point where
# the stack can be reallocated.
# -DHARDMEMTESTS forces a full collection at all points where the collector
# can run.
# -DEMERGENCYGCTESTS forces an emergency collection at every single allocation.
# -DEXTERNMEMCHECK removes internal consistency checking of blocks being
# deallocated (useful when an external tool like valgrind does the check).
# -DMAXINDEXRK=k limits range of constants in RK instruction operands.
# -DLUA_COMPAT_5_3

# -pg -malign-double
# -DLUA_USE_CTYPE -DLUA_USE_APICHECK

# The following options help detect "undefined behavior"s that seldom
# create problems; some are only available in newer gcc versions. To
# use some of them, we also have to define an environment variable
# ASAN_OPTIONS="detect_invalid_pointer_pairs=2".
# -fsanitize=undefined  (you may need to add "-lubsan" to libs)
# -fsanitize=pointer-subtract -fsanitize=address -fsanitize=pointer-compare

# Test mode: Add test library, turn on asserts, redefine several
# constants ("to give some bugs a chance"), track memory use, and add
# debug information.
