+ild

The +ild option specifies incremental linking. If the output file does not exist, or if it was created

without the +ild option, the linker performs an initial incremental link. The output file produced

is suitable for subsequent incremental links. The incremental link option is valid for both executable

and shared library links. It is not valid for relocatable links, options or tools that strip the output

module, and certain optimization options.

When sum reduction optimization is enabled, the compiler may evaluate intermediate partial sums

of float or double precision terms using (wider) extended precision, which reduces variation in the

result caused by different optimization strategies and generally produces a more accurate result.

See ld(1) manpage for more information.

+ildrelink

The +ildrelink option performs an initial incremental link, regardless of the output load module.

In certain situations during incremental linking (for example, internal padding space is exhausted),

the incremental linker is forced to perform an initial incremental link. The +ildrelink option

allows you to avoid such unexpected initial incremental links by periodically rebuilding the output

file.

See ld(1) manpage for more information.

Options for Naming the Output File

These options allow you to name the compilation output file something other than the default name.

-o

-o outfile

The outfile parameter is the name of the file containing the output of the compilation. This option

causes the output of the compilation to be placed in outfile.

Without this option the default name is a.out. When compiling a single source file with the -c

option, you can use the -o option to specify the name and location of the object file.

-.suffix

The suffix parameter represents the character or characters to be used as the output file name

suffix. suffix cannot be the same as the original source file name suffix. Using this option causes

the compiler to direct output from the -E option into a file with the corresponding .suffix instead

of into a corresponding .c file.

Example:

aCC -E -.i prog.C

This command preprocesses the code in prog.C and puts the resulting code in the file prog.i.

Native Language Support Option

The following is an option to enable native language support:

-Y

The -Y option enables Native Language Support (NLS) of 8-bit, 16-bit and 4-byte EUC characters

in comments, string literals, and character constants.
