+ bool "Enable tiny printf() version"
help
- Since sprintf() can overflow its buffer, it is common to use
- snprintf() instead, which knows the buffer size and can avoid
- overflow. However, this does increase code size slightly (for
- Thumb-2, about 420 bytes). Enable this option for safety when
- using sprintf() with data you do not control.
+ This option enables a tiny, stripped down printf version.
+ This should only be used in space limited environments,
+ like SPL versions with hard memory limits. This version
+ reduces the code size by about 2.5KiB on armv7.

+ The supported format specifiers are %c, %s, %u/%d and %x.
