Hello,
There is an mapping alias tag bug when Creating NystromAliasAnalyzer for PU
in IPA phase.
curFilePUIdx() returns a UINT32 which is inconsistance of UINT64 for
cg_st_idx. All these leads to incorrect mapping to an alias tag
The fixed patch is as follows:

cg = _constraintGraph;
if (ipaMode()) {
- cg_st_idx = IPA_CG_ST_st_idx(curFilePUIdx(), st);
+ cg_st_idx = IPA_CG_ST_st_idx((UINT64)curFilePUIdx(), st);
}
else {
cg_st_idx = CG_ST_st_idx(st);
Could a gate keeper check this?
