/* These are the printf/scanf related newlib functions present in ESP32 ROM.
These functions are compiled with newlib "nano" format option.
As such, they don's support 64-bit integer formats.
Floating point formats are supported by setting _printf_float and
_scanf_float entries in syscall table. This is done automatically
by startup code.
These functions should not be used when compiling with PSRAM cache workaround enabled.
See also esp32.rom.newlib-data.ld for the list of .data/.bss symbols
used by newlib functions, and esp32.rom.newlib-funcs.ld for the list
of general newlib functions.
Unlike other ROM functions which are exported using PROVIDE, which declares
weak symbols, newlib related functions are exported using assignment,
which declares strong symbols. This is done so that ROM functions are always
used instead of the ones provided by libc.a.
