The fix is just that getOther had not been updated for packing the st_other values in fewer bits and could return spurious values: - unsigned Other = (getFlags() & (0x3f << ELF_STO_Shift)) >> ELF_STO_Shift; + unsigned Other = (getFlags() & (0x7 << ELF_STO_Shift)) >> ELF_STO_Shift; Original message: Pack the MCSymbolELF bit fields into MCSymbol's Flags. This reduces MCSymolfELF from 64 bytes to 56 bytes on x86_64. While at it, also make getOther/setOther easier to use by accepting unshifted STO_* values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@239012 91177308-0d34-0410-b5e6-96231b3b80d8
