1 # This class exists to provide information about the targets that
2 # may be needed by other classes and/or recipes. If you add a new
3 # target this will probably need to be updated.
6 # Returns information about 'what' for the named target 'target'
7 # where 'target' == "<arch>-<os>"
10 # * target: Returns the target name ("<arch>-<os>")
11 # * endianess: Return "be" for big endian targets, "le" for little endian
12 # * bits: Returns the bit size of the target, either "32" or "64"
13 # * libc: Returns the name of the c library used by the target
15 # It is an error for the target not to exist.
16 # If 'what' doesn't exist then an empty value is returned
