21    Compilers that generate assembly code may produce  global labels
22    whose value is resolved at link time. The various peephole optimization
23    modules did not take this in account.
24    
25    TODO. The Labels.addrOf function should really return an option
26    type so that clients are forced to deal with this issue, rather
27    than an exception being raised.

35    1. A bug fix from Allen.
36    
37        A typo causes extra fstp %st(0)'s to be generated at compensation
38        edges, which might cause stack underflow traps at runtime.  This
39        occurs in fft where there are extraneous fstps right before the 'into'
40        trap instruction (in this case they are harmless since none of the
41        integers overflow.)
42    
43    2. Pulled out various utility modules that were embedded in the modules
44       of the register allocator. I need these modules for other purposes, but
45       they are not complete enough to put into a library (just yet).
