    r1099 r1700  
    77  subset of the MIPS assembly language[2].

    9   We wrote 3 compiler passes: one from Clight to Cminor, another from
    10   Cminor to an abstract register transfer language (RTLabs), and a
    11   last one from RTLabs to an RTL that uses MIPS instructions. We
    12   extended interpreters for the intermediate languages to output a
    13   list of labels which denote key control points of the program that
    14   have been crossed during the interpretation. These labels are the
    15   places where the code can be instrumented to obtain a precise cost
    16   annotation. Thus, in that experiment, the annotation function is the
    17   composition of a labelling function followed by an instrumentation
    18   function.
     9  We rewrote the whole chain from Clight down to ASM, targetting the
     10  8051 architecture. We extended interpreters for the intermediate
     11  languages to output a list of labels which denote key control points
     12  of the program that   have been crossed during the interpretation.
     13  These labels are the places where the code can be instrumented to
     14  obtain a precise cost annotation. Thus, in that experiment, the
     15  annotation function is the composition of a labelling function
     16  followed by an instrumentation function. Labels are moreover indexed
     17  by iterations in loop, so that some loop transformations can be
     18  carried out without impacting the approach. Other implemented
     19  optimizations are constant propagation, copy propagation and partial
     20  redundancy elimination.
