21 # This is the libgcc host-specific configuration file
|
|
|
22 # where a configuration type is mapped to different system-specific
|
|
|
23 # definitions and files. This is invoked by the autoconf-generated
|
|
|
24 # configure script. Putting it in a separate shell file lets us skip
|
|
|
25 # running autoconf when modifying host-specific information.
|

26
|
|
|
27 # This file bears an obvious resemblance to gcc/config.gcc. The cases
|
|
|
28 # should be kept similar, to ease moving library-specific settings
|
|
|
29 # from config.gcc to this file. That is also why tmake_file is
|
|
|
30 # left as tmake_file, rather than hmake_file, even though this library
|
|
|
31 # switches on ${host}.
|
|
|
32
|
|
|
33 # This file switches on the shell variable ${host}, and also uses the
|
|
|
34 # following shell variables:

35 #
|
|
|
36 # with_* Various variables as set by configure.
