Hi,
It appears that the code in engines/e_aep.c has an "#ifdef
SIXTY_FOUR_BIT_LONG" to decide on things like BigNumSize (right shift by
3 or by 2, etc.).
However, there is also the macro SIXTY_FOUR_BIT, which is another way to
change BN_BYTES to 8 instead of 4. Should the #ifdefs in
engines/e_aep.c be checking both SIXTY_FOUR_BIT_LONG and SIXTY_FOUR_BIT?
I've just started looking at the code so could be very wrong =)
The reason I started looking into this, is that I have a target which is
ILP32, but does actually support 64-bit loads/stores and arithmetic. So,
I wanted to use the SIXTY_FOUR_BIT configuration for better performance.
Here's a diff for changing e_aep.c:
If we are to do something about e_aep.c, then I'd be something
#ifdef-free like
