See e.g. config/arm/lib1funcs.S: #define SYM(x) CONCAT1 (__USER_LABEL_PREFIX__, x) (and the associated macro definition of CONCAT1 that uses, etc.). If you have .S sources that may be used on targets both with and without a prefix, you should do something similar. (The ELF gABI says "External C symbols have the same names in C and object files' symbol tables.", so ELF targets using leading underscores on C symbol names are going against the gABI.) -- Joseph S.
