If you are compiling multiple source files, this option tells the driver

to pass all the source files to the compiler at once (for those

languages for which the compiler can handle this). This will allow

intermodule analysis (IMA) to be performed by the compiler. Currently the only
|
||||
language for which this is supported is C@. If you pass source files for
|
||||
multiple languages to the driver, using this option, the driver will invoke
|
||||
the compiler(s) that support IMA once each, passing each compiler all the
|
||||
source files appropriate for it. For those languages that do not support
|
||||
IMA this option will be ignored, and the compiler will be invoked once for
|

each source file in that language. If you use this option in conjunction
