2.18. Command File Option

Sometimes the list of command-line options that are used during the invocation of a compiler can become unwieldy. The @ option described below provides a mechanism for collecting command-line options and input file specifications into a text file that can be fed into the compiler as a sort of extension of the compiler invocation command.

armcl Option	tiarmclang Option
--cmd_file=<file> (-@=<file>)	@<file>

Both the armcl and tiarmclang compilers provide an option that allows the use of a the specified <file>’s contents as an extension for the command-line used to invoke the compiler. The tiarmclang version of the option should not be preceded with a hyphen.
