           Summary: SetLE/GE/LT/GT On Loaded Long Arguments Always Returns
                    FALSE
           Product: libraries

The attached test case loads two longs from global constants (7 and 49),
compares them with SetLE, casts them to int, and returns the value from main.
This should give a program with a result value of 0 or 1. However, it always
returns 0. It should return 1 because 7 <= 49.

Here's the test case:

%global_long_1 = linkonce global long 7
%global_long_2 = linkonce global long 49
                                                                               
                                                            
implementation   ; Functions:
                                                                               
                                                            
declare void %exit(int)
                                                                               
                                                            
int %main() {
        %long_1 = getelementptr long* %global_long_1, long 0
        %long_2 = getelementptr long* %global_long_2, long 0
                                                                               
                                                            
        %l1 = load long* %long_1
        %l2 = load long* %long_2
                                                                               
                                                            
        %cond = setle long %l1, %l2
        %cast2 = cast bool %cond to int
        ret int %cast2
}
