-qsaveopt

Command-line compiler options information is copied as a string into the object file, using the following format:

>>-@(#)--opt--+-f-+--invocation--options-----------------------><
              +-c-+                        
              '-C-'                        

>>-@(#)--cfg----config_file_options_list-----------------------><

>>-@(#)--env----env_var_definition-----------------------------><

where:

f

Signifies a Fortran language compilation.

c

Signifies a C language compilation.

C

Signifies a C++ language compilation.

invocation

Shows the command used for the compilation, for example, xlc.

options

The list of command line options specified on the command line, with individual options separated by space.

config_file_options_list

The list of options specified by the options attribute in all configuration files that take effect in the compilation, separated by space.

env_var_definition

The environment variables that are used by the compiler. Currently only XLC_USR_CONFIG is listed.

Note: You can always use this option, but the corresponding information is only generated when the environment variable XLC_USR_CONFIG is set.

For more information about the environment variable XLC_USR_CONFIG, see Compile-time and link-time environment variables.

Compiler version and release information, as well as the version and level of each component invoked during compilation, are also saved to the object file in the format:

>>-@(#)--------------------------------------------------------->

   .-------------------------------------------------------------------------------------------------------------.   
   V                                                                                                             |   
>----version--+-Version-- : -VV.RR.MMMM.LLLL-------------------------------------------------------------------+-+-><
              '-component_name--Version--:--VV.RR--(--product_name--)--Level--:--YYMMDD--:--component_level_ID-'     

where:

V

Represents the version.

R

Represents the release.

M

Represents the modification.

L

Represents the level.

component_name

Specifies the components that were invoked for this compilation, such as the low-level optimizer.

product_name

Indicates the product to which the component belongs (for example, C/C++ or Fortran).

YYMMDD

Represents the year, month, and date of the installed update. If the update installed is at the base level, the level is displayed as BASE.

component_level_ID

Represents the ID associated with the level of the installed component.
