+------- Additional Comments From bmaurer at users.sf.net  2005-07-03 11:15 -------
+There are 4 variables inside the loop. The design of our register
+allocator only allows us to use 3 registers for global registers. MSFT
+is able to use eax, ecx, edx for global variables.
+
+Fixing this will require a new regalloc.
+
+Am marking as INVALID because the new regalloc doesn't really need a
+bugzilla entry. We know about it, and will do it in the future.
