Hum. So, not entirely incompatible with the gnu ifunc extension, but certainly not exactly like it either. Off and on I've been pondering, post-toplevel-libgcc-move, whether it would make sense to implement the functions therein with different ISAs and either select the proper version with pre-processor macros (generating a target-specific libgcc) or with ifuncs if available. What support does the Solaris 11 assembler have for this feature? The documentation only mentions the compiler... r~
