What rationale are you referring to?  There hasn't been an official ISO
C Rationale document since C99.

Why would pointers to _BitInt types be a problem?  A _BitInt object is
a fixed-size chunk of memory, similar to a struct object.

Why is that a problem?  If you don't want odd-sized types, don't use them.

The upper limit is specified by the implementation as BITINT_MAXWIDTH, a
macro defined in <limits.h>.

For gcc 15.2.0 on x86_64, BITINT_MAXWIDTH is 65535 (2**16-1).
For clang 21.1.5 it's 8388608 (2**23 bits, 1048576 bytes).

clang seems to have some problems with _BitInt(8388608).  For example,
this program:

#include <limits.h>

_BitInt(BITINT_MAXWIDTH) n = 42;

int main(void) {
    n *= n;
}

takes a *long* time to compile with clang.  I believe it's generating
inline code to do the 8388608 by 8388608 bit multiplication.

> So what is the result type of multiplying values of those two types?

_BitInt types are exempt from the integer promotion rules (so _BitInt(3)
doesn't promote to int), but the usual arithmetic conversions apply.
If you multiply values of two _BitInt types, the result is the wider of
the two types.

N3220 is a draft of C23.

_BitInt(n) objects are fixed-size.  Addition and subtraction should be
fairly straightforward.  For multiplication and division, gcc generates
calls to __mulbitint3 and __divmodbitint4, and clang generates huge
amounts of inline code.  My guess is that future llvm/clang releases
will handle _BitInt types more efficiently.
