--- Comment #7 from David Binderman <dcb314 at hotmail dot com> --- I tried: $ git fetch --shallow-since=1/1/2021 and the blame still has ^ on the front of it. ^abca670596 libcpp/lex.c (Ian Lance Taylor 2020-12-31 11:23:30 -0800 869) /* Align the source pointer. */ ^abca670596 libcpp/lex.c (Ian Lance Taylor 2020-12-31 11:23:30 -0800 870) misalign = (uintptr_t)s & 15; ^abca670596 libcpp/lex.c (Ian Lance Taylor 2020-12-31 11:23:30 -0800 871) p = (const uint8_t *)((uintptr_t)s & -16); ^abca670596 libcpp/lex.c (Ian Lance Taylor 2020-12-31 11:23:30 -0800 872) data = vld1q_u8 (p); IMHO, most ARM bugs seem to land in the in-tray of Richard Sandiford. Maybe Richard might recognise the code ?
