1# compiler-rt Library Info

3# This should be included once the subdirectory information has been loaded, and
4# uses the utilities in 'util.mk'.
5#
6# This defines the following variables describing compiler-rt:
7#   AvailableFunctions   - The entire list of function names (unmangled) the
8#                          library can provide.
9#   CommonFunctions      - The list of generic functions available.
10#   ArchFunctions.<arch> - The list of functions commonly available for
11#                          'arch'. This does not include any config specific
12#                          functions.
13#
14#   AvailableIn.<function> - The list of subdir keys where 'function' is
15#                            defined.
