Hello Eric,
bswapdi2 is implemented in libgcc2.c as follows:
#ifdef L_bswapdi2
DItype
__bswapdi2 (DItype u)
{
...
}
#endif
One way to avoid compilation of this function is to add condition macros
like: #if LONG_LONG_TYPE_SIZE > 32
However, libgcc2.h does not have such facility and declaration will be
included unconditionally. This will cause compilation failure if DItype
is not supported. I guess, libgcc2.h does not declare most of functions
with explicit SItype or DItype, it mostly uses Wtype and DWtype. Please
correct me if I am wrong. It would be very helpful to conditionally
declare such functions in libgcc2.h.
Thanks a lot for looking into this matter. I will be waiting for you
next mail.
Regards,
Pompa

Hello Eric,
The target I am working on is 16-bit target and cannot support 64-bit
data types (DI mode).
How about conditionally declare the function?
#if LONG_LONG_TYPE_SIZE > 32
extern DItype __bswapdi2 (DItype);
#endif
You'll want to do it where the function is compiled, see other
functions that use DItype. :)
Or, I'll probably get to it in a day or two...
