# Used by        : avr-gcc compiler driver
# Used for       : building command options for sub-processes

# See <https://gcc.gnu.org/onlinedocs/gcc/Spec-Files.html>

# If you intend to use an existing device specs file as a starting point
# for a new device spec file, make sure you are copying from a specs
# file for a device from the same core architecture and SP width.
# See <https://gcc.gnu.org/gcc-5/changes.html> for a description
# of how to use such own spec files.

# AVR-LibC's avr/io.h uses the device specifying macro to determine
# the name of the device header.  For example, -mmcu=atmega8a triggers
# the definition of __AVR_ATmega8A__ and avr/io.h includes the device
# header 'iom8a.h' by means of:
#
#     ...
#     #elif defined (__AVR_ATmega8A__)
#     #  include <avr/iom8a.h>
#     #elif ...
# 
# If no device macro is defined, AVR-LibC uses __AVR_DEV_LIB_NAME__
# as fallback to determine the name of the device header as
#
#     "avr/io" + __AVR_DEV_LIB_NAME__ + ".h"
#
# If you provide your own specs file for a device not yet known to
# AVR-LibC, you can now define the hook macro __AVR_DEV_LIB_NAME__
# as needed so that
#
#     #include <avr/io.h>
#
# will include the desired device header.  For ATmega8A the supplement
# to *cpp would read
#
#     -D__AVR_DEV_LIB_NAME__=m8a
