+# Generated by   : ./gcc/config/avr/gen-avr-mmcu-specs.c
+# Generated from : ./gcc/config/gcc.c
+#                  ./gcc/config/avr/specs.h
+#                  ./gcc/config/avr/avrlibc.h
+# Used by        : avr-gcc compiler driver
+# Used for       : building command options for sub-processes

+# file for a device from the same core architecture and SP width.
+# See <https://gcc.gnu.org/gcc-5/changes.html> for a description

+# 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
