Ronnie,
Why do you change all function argumentns to use _U_ ?
_U_ is only used to mark a parameter as unused so that the compiler
will not emit any warnings "parameter foo is never used".
You only set this _U_ for arguments that are indeed never used inside
the function to suppress these kinds of compiler warnings.
Can you resubmit the patch after removing and reviewing these _U_ changes?
The problem here is that we are generating the code. In case we want to
remove obsolete _U_s we would have to do generation in 2 passes (1st
pass collects all the variables that will be actually used in the code,
2nd pass generates the code). Is the issue critical for you?
Martin
