// Entry:
-// Arguments are passed on the stack:

-// 2nd pushed: dividend (QWORD)
+// EDX:EAX - long value to be shifted
+// CL - number of bits to shift by
//
// Exit:
-// EDX:EAX contains the quotient (dividend/divisor)
-// NOTE: this routine removes the parameters from the stack.

-// ullshr - long shift right
-//
-// Purpose:
-// Does a unsigned Long Shift Right
-// Shifts a long right any number of bits.
-//
-// Entry:
-// EDX:EAX - long value to be shifted
-// CL - number of bits to shift by
-//
-// Exit:
-// EDX:EAX - shifted value
-//
-// Uses:
-// CL is destroyed.
-//
-
-__aullshr:
-
-//
-// Handle shifts of 64 bits or more (if shifting 64 bits or more, the result
-// depends only on the high order bit of edx).
-//
- cmp cl,64
- jae short ..RETZERO
-
-//
-// Handle shifts of between 0 and 31 bits
-//
- cmp cl, 32
- jae short ..MORE32
- shrd eax,edx,cl
- shr edx,cl
- ret
-
-//
-// Handle shifts of between 32 and 63 bits
-//
-..MORE32:
- mov eax,edx
- xor edx,edx
- and cl,31
- shr eax,cl
- ret
-
-//
-// return 0 in edx:eax
-//
-..RETZERO:
- xor eax,eax
- xor edx,edx
- ret
