# 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
