Alpha, IA-64, MIPS, HP-PA, > SPARC and a few others have an override for ASM_GENERATE_INTERNAL_LABEL. I am aware of these cases. And when I took at look at them it seemed to me that these base target headers where you see those defines either do not get used alongside elfos.h or will come before elfos.h in the tmake file listing, thus the elfos.h definition will take precedence. On the other hand, on Sparc, the overrides occur in OS specific target headers which appear after elfos.h in the tmake header file list. >> The normal thing to do is to use the elfos.h defines as-is. > > Target macros are meant to be overridden though.
