Hello,
Is there a way (i.e. a trace flag) to print the very-low whirl which is
used internally in the code generator?
-Wb,-trlow will print out the whirl as it is lowered, with the last dump
showing the whirl that enters CG. Note that CG itself takes whirl input
and immediately translates it to instructions and then operates on the
instructions. -Wb,-ttexp:7 will show the translation of whirl into
CG's instruction format (TOPs). -Wb,-trexp will show show the TOPs after
cgexp, which is the first phase of CG.
Is it possible to print out information about register content,: for
exampe: register Ri has the address of array a, etc.
Not really, because the same register can hold multiple values at different
times. The .s file has comments that show what object a memory location
refers to, which is also in dumps like -Wb,-tremt (the final representation
of TOPs).
