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
Thanks,
Pompa

Hello,
Current function declaration of __bswapdi2 in libgcc2.h is:
DItype __bswapdi2 (DItype u)
Since this declaration does not check if DItype is supported, it is
bound for compilation failure for targets that do not support DItype.
Would it be ok to change the DItype to DWtype as in:
DWtype __bswapdi2 (DWtype u)
Is the above declaration more safer for all targets?
No, probably best would be a check to make sure DItype is defined. In
this case it's not a double word operation it is explicitly a 64-bit
operation.
