21 The intention of this file is to supply definitions that work with
|
|
|
22 avr-gcc's -mint8 that sets int to an 8-bit type.
|
|
|
23
|
|
|
24 This file is intended to yield the same results as newlib-stdint.h,
|
|
|
25 but there are some differences to newlib-stdint.h:
|
|
|
26
|
|
|
27 - AVR is an 8-bit architecture that cannot access 16-bit values
|
|
|
28 atomically, this SIG_ATOMIC_TYPE is "char".
|
|
|
29
|
|
|
30 - For the same reason, [u]int_fast8_t is defined as 8-bit type.
