-g

Instructs both the compiler and the linker to prepare the file or program for debugging.

The tasks include:

• Producing detailed information, known as stabs, in the symbol table of the object files and the executable

• Producing some "helper functions," which the debugger can call to implement some of its features

• Disabling the inline generation of functions

• Disabling certain levels of optimization

Interactions

You can use this option with -xO to get the optimization level that you desire.

If you use this option with -xO, you will get limited debugging information.

When you specify this option, the +d option is specified automatically.

This option makes -xildon the default incremental linker option in order to speed up the compile-edit-debug cycle.

This option invokes ild in place of ld unless any of the following are true:

• The -G option is present

• The -xildoff option is present

• Any source files are named on the command line
