# newlib second-part options
config LIBC_NEWLIB_IO_C99FMT
bool
prompt "Enable IOs on C99 formats"
help
Enable support for IOs on C99 formats.
config LIBC_NEWLIB_IO_LL
bool
prompt "Enable IOs on long long"
help
Enable support for IOs on long long integers.
config LIBC_NEWLIB_IO_FLOAT
bool
prompt "Enable IOs on floats and doubles"
help
Enable support for IOs on floating point
values (float and double).
config LIBC_NEWLIB_IO_LDBL
bool
prompt "Enable IOs on long doubles"
depends on LIBC_NEWLIB_IO_FLOAT
help
Enable support for IOs on long doubles.
config LIBC_NEWLIB_DISABLE_SUPPLIED_SYSCALLS
bool
prompt "Disable the syscalls supplied with newlib"
help
Disable the syscalls that come with newlib. You
will have to implement your own _sbrk, _read,
_write... If you plan to port newlib to a new
platform/board, say Yes.
config LIBC_NEWLIB_ENABLE_TARGET_OPTSPACE
bool
prompt "Optimize newlib for size"
default y
help
Pass --enable-target-optspace to newlib configure.
This will compile newlib with -Os.
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.
config LIBC_NEWLIB_EXTRA_CONFIG_ARRAY
string
prompt "Extra config for newlib"
default ""
help
Extra flags to pass onto ./configure when configuring the newlib.
