Hello:
I am using GreenCard to
import some C code into Haskell. The code I want to import uses
"long" in a lot of places. I tried to write my own DIS for it
and I also write a very simple test program. However, the DIS
does not work properly. My program and test result are as following:
--------------------------------------------------------------------------
module TLong where
import Foreign.GreenCard
type Long = Int64
%dis long x = int64 x %dis int64 x = %%Int64 ({HsInt64}
x)
%fun tslong :: Long -> Long
%call (long a1) %code long a2; % a2 = a1; % printf("the long integer is %d the original is %d \n", a2, a1); %result (long (a2)) ------------------------------------------------------------------------------ .....
TLong>tslong 1
the long integer is -1073752653 the original is
-10173752653
-4611732526480752641
------------------------------------------------------------------------------
I know it is caused
by my DIS, but I have no idea what is the right way to do it. Does anyone
know the right way to do it?
Best Regards
Liwen |
