# This shell script handles all target based configuration for libstdc++.
|
|
# It sets various shell variables based on the the target and the

|
# configuration options. You can modify this shell script without
|
|
# needing to rerun autoconf.
|

# This shell script should be invoked as

|
# . configure.target
|
|
# If it encounters an error, it will exit with a message.

# It uses the following shell variables:
|
|
# target The configuration target
|
|
# target_cpu The configuration target CPU
|
|
# target_os The configuration target OS
|
|

|
# It possibly modifies the following shell variables:
|
|
# cpu_include_dir CPU-specific include directory, relative to srcdir
|
|
#
|
|
# os_include_dir OS-specific include directory, relative to srcdir
|
|
#
|
|
# c_model the model to use for "C" headers, defaults to c_std.
