Hi,
I am reading the code of autovect branch and curious about how to deal
with the dependencies of virtual defs/uses. In the function
vect_analyze_scalar_cycles( ), I found the statement "Skip virtual
phi's. The data dependences that are associated with virtual defs/uses
( i.e., memory accesses) are analyzed elsewhere." But where is the
code? I tried to search for "vect_induction_def" and
"vect_reduction_def" and found that they are not used to assign
elsewhere. Is the analysis not implemented yet? Thanks in advance!
