David Green eecba95067 [ARM] Replace arm vendor with none. NFC 2020-04-22 18:19:35 +01:00
Anna Welker 394974111b [ARM][MVE] Restrict allowed types of gather/scatter offsets 
The MVE gather instructions smaller than 32bits zext extend the values
in the offset register, as opposed to sign extending them. We need to
make sure that the code that we select from is suitably extended, which
this patch attempts to fix by tightening up the offset checks.
