This feature is possibly - unnecessary for embedded systems which won't change file buffering - with functions like `setbuf' or `setvbuf'. The buffering mechanism - still acts as default for STDIN/STDOUT/STDERR even if this option - is specified. - -config LIBC_NEWLIB_UNBUF_STREAM_OPT - bool - prompt "Optimize fprintf to unbuffered unix file" - default y - help - NEWLIB does optimization when `fprintf to write only unbuffered unix - file'. It creates a temorary buffer to do the optimization that - increases stack consumption by about `BUFSIZ' bytes. Disabling this option - disables the optimization and saves size of text and stack. - -config LIBC_NEWLIB_FSEEK_OPTIMIZATION - bool - prompt "Fseek optimisation" - default y - help - Disabling fseek optimisation can decrease code size. - -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_REGISTER_FINI - bool - prompt "Enable finalization function registration using atexit" - help - Enable finalization function registration using atexit. - -config LIBC_NEWLIB_ATEXIT_DYNAMIC_ALLOC - bool - prompt "Enable dynamic allocation of atexit entries" - default y - help - Enable dynamic allocation of atexit entries. - -config LIBC_NEWLIB_GLOBAL_ATEXIT - bool - prompt "Enable atexit data structure as global variable" - help - Enable atexit data structure as global variable. By doing so it is - move out of _reent structure, and can be garbage collected if atexit - is not referenced. - -config LIBC_NEWLIB_LITE_EXIT - bool - prompt "Enable lite exit" - help - Enable lite exit, a size-reduced implementation of exit that doesn't - invoke clean-up functions such as _fini or global destructors. - -config LIBC_NEWLIB_REENT_SMALL - bool - prompt "Enable small reentrant struct support" - help - Enable small reentrant struct support. - -config LIBC_NEWLIB_MULTITHREAD - bool - prompt "Enable support for multiple threads" - default y - help - Enable support for multiple threads. - -config LIBC_NEWLIB_EXTRA_SECTIONS - bool - prompt "Place each function & data element in their own section" - help - Place each function & data symbol in their own section. This allows - the linker to garbage collect unused symbols at link time. - -config LIBC_NEWLIB_WIDE_ORIENT - bool - prompt "Allow wide C99 stream orientation" - default y - help - C99 states that each stream has an orientation, wide or byte. This - feature is possibly unnecessary for embedded systems which only do - byte input/output operations on stream. Disabling this feature can - decrease code size. - -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_LTO - bool - prompt "Enable Link Time Optimization" - depends on CC_GCC_USE_LTO - help - Builds the libraries with -flto to enable more aggressive link time - optimization. You will need to add -flto-partition=one to your - application's link line to keep the RETURN assembler macro together - with it's consumers. - -config LIBC_NEWLIB_NANO_MALLOC - bool - prompt "Enable Nano Malloc" - depends on NEWLIB_HAS_NANO_MALLOC - 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 NEWLIB_HAS_NANO_FORMATTED_IO - 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. |
