excluding visibility bits. Generic STO handling at the Target level. The st_other field of the ELF symbol table is one byte in size. The first 2 bytes are used for generic visibility and are currently handled by llvm. The other six bits are processor specific and need to be set at the target level. A couple of notes: The new static methods for accessing and setting the "other" flags in include/llvm/MC/MCELF.h match the style guide and not the other methods in the file. I don't like the inconsistency, but feel I should follow the prescribed lowerUpper() convention. STO_ value definitions are not specified in gnu land as consistently as the STT_ and STB_ fields. Probably because the latter were defined in a standards doc and the former defined partially in code. I have stuck with the full byte definition of the flags.
