Entries *can* have a "?" to indicate they are optional (although avoiding the PLT reference is better - see how include/string.h does asm redirection of mempcpy and stpcpy, or likewise in sysdeps/wordsize-32/divdi3-symbol-hacks.h, for example). > ARC historically has supported both LE/BE, but we are kind of moving > away from BE and as far as I know, there's no-one actively working with > BE (except 1 specific customer with legact cores).

In that case, there should be a #error in bits/endian.h, or a configure-time error, or something like that, to make clear the glibc port does not support BE. -- Joseph S. Myers joseph@codesourcery.com
