Hello,
Is it true that in a SET, a search for a _use_ of a register
in the LHS should be done only inside a memory address?
Also within the second and third arguments of a ZERO_EXTRACT. And its
first argument may be a MEM, in which case you should look into it.
Look at df_uses_record in df.c for more information.
But you can simply use the data flow info you compute, and just avoid
uses that have the DF_REF_READ_WRITE flag set (because they occur in the
LHS, or within an autoincrement/autodecrement)?
