/* These are the printf/scanf related newlib functions present in ESP32-S2 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.
|
||
|
|
See also esp32s2.rom.newlib-data.ld for the list of .data/.bss symbols
|
||
|
|
used by newlib functions, and esp32s2.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.
