SDCC has had memset_explicit since SDCC 4.2.0 (released 2021), and this
is the implementation:
#include <string.h>
void *memset_explicit (void *s, int c, size_t n)
{
return(memset(s, c, n));
}
Since SDCC does not have link-time optimization, and the implementation
resides in its own source file by itself, this is sufficient to ensure
that it does not get optimized out.
