Datasheet

C and C++ Compilers

debug-options

This specifies whether or not debug tables are generated, and their

format. See Generating debug information on page 2-22 for

details.

code-generation-options

This specifies options such as optimization, byte order, and

alignment of data produced by the compiler. See Controlling code

generation on page 2-24 for details.

warning-options

This specifies whether specific warning messages are generated.

See Controlling warning messages on page 2-31 details.

additional-checks

This specifies several additional checks that can be applied to your

code, such as checks for data flow anomalies and unused

declarations. See Specifying additional checks on page 2-35 for

details.

error-options

This enables you to turn off specific recoverable errors or

downgrade specific errors to warnings. See Controlling error

messages on page 2-37 for details.

source

This provides the filenames of one or more text files containing C

or C++ source code. By default, the compiler looks for source

files, and creates output files, in the current directory.

If a source file is an assembly file (that is, one with an

extension) the assembler activates to process the source file.

Reading compiler options from a file

When the operating system restricts the command line length, use the following option

to read additional command-line options from a file:

-via filename

This opens a file and reads additional command-line options from it. You can nest

-via

calls within via files by including

-via filename2

in the file.

In the following example, the options specified in

input.txt

are read as the

command-line is parsed:

armcpp -via input.txt source.c

See Appendix A Via File Syntax for more information on writing via files.
