What is the best method to enumerate all xrefs to addresses in a particular segment? I came up with a brute-force approach (as seen below). The code scans each address in a segment and checks for an XrefTo the address.
seg_list =  for seg in Segments(): seg_list.append(seg) # logic will be added to remove section that are code later seg_list.reverse() for seg in seg_list: start = SegStart(seg) end = SegEnd(seg) while start < end: gen_xrefs = XrefsTo(start, 0) for xx in gen_xrefs: print hex(start), hex(xx.frm) start += 1
This approach is very time consuming if I have multiple large segments. IDA adds
DATA XREF comments when viewing the data manually. Are these xrefs stored in an accessible way from IDAPython or is there another more practical approach to find the xrefs to a segment?
mem_15d:00973000 dd 1C8h dup(0) mem_15d:00973720 dword_973720 dd 101011Ch, 1000h ; DATA XREF: mem_f08:00970678o mem_15d:00973728 off_973728 dd offset off_970178 ; DATA XREF: mem_f08:off_970178o mem_15d:00973728 ; mem_f08:0097017Co
Note: Enumerating all xrefs from the code is not an option.
