The Oracle Solaris x86 assembler as translates Oracle Solaris x86 assembly language into Executable and Linking Format (ELF) relocatable object files that can be linked with other object files to create an executable file or a shared object file. (See Chapter 14, Object File Format in Oracle Solaris 11.4 Linkers and Libraries Guide for a complete discussion of ELF object file format.) The assembler supports macro processing by the C preprocessor (cpp) or the m4 macro processor.
