; The "bug" is in the level raising code, not correctly
|
|
; raising an array reference. As generated, the code will work, but does
|
|
; not correctly match the array type. In short, the code generated
|
|
; corresponds to this:
|
|
;
|
|
; int Array[100][200];
|
|
; ...
|
|
; Sum += Array[0][i*200+j];
|
|
;
|
|
; which is out of range, because, although it is correctly accessing the
|
|
; array, it does not match types correctly. LLI would pass it through fine,
|
|
; if only the code looked like this:
|
|
;
|
|
; Sum += Array[i][j];
|
|
;
|
|
; which is functionally identical, but matches the array bound correctly.
|
|
; The fix is to have the -raise pass correctly convert it to the second
|
|
; equivelent form.
