Description:

The xlC and related commands compile C and C++ source files.

The xlC and related commands compile C and C++ source files.

They also processes assembler source files and object files. Unless the -c option is specified, xlC calls the linkage editor to produce a

single object file. Input files may be any of the following:

1. file name with .C suffix: C++ source file

2. file name with .i suffix: preprocessed C or C++ source file

3. file name with .c suffix: C source file

4. file name with .o suffix: object file for ld command

5. file name with .s suffix: assembler source file

6. file name with .so suffix: shared object file

Options:

Options can be flag options or keyword options:

1. Flag options:

-# Display language processing commands but do

not invoke them; output goes to stdout.

-+ Treat .c files as C++ source code.

-bdynamic, -bstatic

Determines which types of library files are searched by

the linkage editor.

-brtl Tells the linkage editor to accept both .so and .a

library file types.

-B

Construct alternate compiler/assembler/linkage editor

program names. is added to the beginning of

the standard program names.

-c Do not send object files to the linkage editor.

-C Write comments to output when doing preprocessing,

used with -E and -P.

-D[=]

Define as in #define directive. If is

not specified, 1 is assumed.

-E Preprocess but do not compile; output goes to stdout

-f

Passes to the linkage editor the filename of a file

containing a list of input files to be processed.

-F[:]

Use alternate configuration file with optional

. If is not specified, the assumed stanza is the name of the command used to invoke the compiler.

-g Produce information for the debugger.

-G Tells the linkage editor to create a dynamic library.

-I

Search in directory for include files that

do not start with an absolute path.

-l Search the specified library file,

where selects the file lib.a.

-L

Search in directory for files specified by -l. -ma Generate inline calls to the "alloca" function as if

"#pragma alloca" directives were in the source file.

-M Generate information to be included in a "make"

description file; output goes to .u file.

-o Name the executable file instead of a.out.

When used with the -c option and one source file,

name the object file instead of filename.o.

If is the name of a directory, files generated by the compiler will be placed into that directory.

-O Optimize generated code.

-O2 Same as -O.

-O3 Perform some memory and compile time intensive

optimizations in addition to those executed with -O2.

The -O3 specific optimizations have the potential to
