config LIBC_NEWLIB_NANO_MALLOC
bool
prompt "Enable Nano Malloc"
depends on LIBC_NEWLIB_2_1_or_later
help
NEWLIB has two implementations of malloc family's functions, one in
`mallocr.c' and the other one in `nano-mallocr.c'. This options
enables the nano-malloc implementation, which is for small systems
with very limited memory. Note that this implementation does not
support `--enable-malloc-debugging' any more.
config LIBC_NEWLIB_NANO_FORMATTED_IO
bool
prompt "Enable Nano Formatted I/O"
depends on LIBC_NEWLIB_2_2_or_later
help
This builds NEWLIB with a special implementation of formatted I/O
functions, designed to lower the size of application on small systems
with size constraint issues. This option does not affect wide-char
formatted I/O functions.
