# Rules:
# * Types, allocators, and classes can be declared.
# * Types, allocators, classes, and descriptions can only contain
#   alphanumeric characters.
# * Allocators and classes have to be declared before they are used in
#   type declarations.
# * Descriptions have only one name space (i.e. class descriptions,
#   allocator descriptions, and type descriptions are all in the same
#   name space).
# * Types, allocators, classes, and descriptions have different name
#   spaces.
# * The type, allocator, and class names INVALID are reserved and can
#   not be used.
# * The descriptions invalid_allocator, invalid_class, and invalid_type
#   are reserved and can not be used.
# * Declarations can be done conditionally by use of a
#     +if <boolean_variable>
#
#     +else
#
#     +endif
#   or a
#     +ifnot <boolean_variable>
#
#     +else
#
#     +endif
#   construct (else branches are optional). The boolean variable X is
#   true after a "+enable X" statement or if it has been passed as a
#   command line argument to make_alloc_types. The variable X is false
#   after a "+disable X" statement or if it has never been mentioned.


# --- Allocator declarations -------------------------------------------------
#
# If, and only if, the same thread performes *all* allocations,
# reallocations and deallocations of all memory types that are handled
# by a specific allocator (<ALLOCATOR> in type declaration), set 
# <MULTI_THREAD> for this specific allocator to false; otherwise, set
# it to true.

# --- Type declarations ------------------------------------------------------
# 
# Syntax: type <TYPE> <ALLOCATOR> <CLASS> <DESCRIPTION>
#
# Use ERTS_ALC_T_<TYPE> as first parameter to erts_alloc(), erts_alloc_fnf(),
# erts_realloc(), erts_realloc_fnf() or erts_free() in order to allocate,
# reallocate or deallocate a memory block of type <TYPE>.
#
# NOTE: Only use temp_alloc for memory types that *really* are *temporarily*
#	allocated. A good thumb rule: all memory allocated by temp_alloc
#       should be deallocated before the emulator starts executing Erlang
#       code again.
#
# NOTE: When adding or removing a type which uses the FIXED_SIZE allocator,
#       also add or remove initialization of the type in erts_alloc_init()
#       (erl_alloc.c).
