Correct.  For those of you keeping score at home, here's the list of the DECC$ functions that are linked into the system base image (some are the same objects as what's in DECC$SHR, others have been compiled a 2nd time to remove code that won't function in the kernel like 'locale support')

        DECC$ATOI                       = PROCEDURE,-

        DECC$SRAND                      = PROCEDURE,-
        DECC$STRTOL                     = PROCEDURE,-

        DECC$MEMSET                     = PROCEDURE,-
        DECC$ABS                        = PROCEDURE,-
        DECC$LABS                       = PROCEDURE)

        DECC$STRNLEN                    = PROCEDURE)

and the matching "W" wide-char flavors (although I'm not sure how much that was necessary other than both forms come in the same .OBJ files)

And a bunch of the OTS$ routines which are from GEM-generated code.

For x86, the OTS$ set is greatly reduced since it isn't GEM as the code generator.  The GEM-to-LLVM converter does turn various GEM IR tuples into OTS$ routine calls just like GEM on Alpha/Itanium does (although at different points in the conversion)
