3.17.28 Options for System V

These additional options are available on System V Release 4 for compatibility with other compilers on those systems:

@gcctabopt -G

Create a shared object. It is recommended that ‘-symbolic’ or ‘-shared’ be used instead.

@gcctabopt -Qy

Identify the versions of each tool used by the compiler, in a .ident assembler directive in the output.

@gcctabopt -Qn

Refrain from adding .ident directives to the output file (this is the default).

@gcctabopt -YP,dirs

Search the directories dirs, and no others, for libraries specified with ‘-l’.

@gcctabopt -Ym,dir

Look in the directory dir to find the M4 preprocessor. The assembler uses this option.
