[matu3ba]

SYSTEM V APPLICATION BINARY INTERFACE SPARC Processor Supplement Third Edition

Support Routines Besides operating system services, libsys contains the following processor-specific support routines.

Figure 6-1: libsys Support Routines docs are not very specific on which are needed and glibc is unreadable) These dould be the regular SPARC symbols and the other the 64bit symbols. TODO: investigate more.
