readOffset.1774_91 is defined  in BB94, by:
readOffset.1774_91 = readOffset_2297
It is also live-on-entry to entry BB 0 So it appears to have multiple defs.
readOffset.1774_2298 is defined  in BB87, by:
readOffset.1774_2298 = readOffset_2299
It is also live-on-entry to entry BB 0 So it appears to have multiple defs.
