Compiler Command-line Options This option takes precedence if you include --pch on the same command line. Syntax --use_pch=filename Where: filename is the PCH file to be used as part of the current compilation. Restrictions The effect of this option is negated if you include --create_pch=filename on the same command line. Errors If the specified file does not exist, or is not a valid PCH file, then the compiler generates an error. See also • --create_pch=filename on page 2-18 • --pch on page 2-70 • --pch_dir=dir on page 2-71 • --[no_]pch_messages on page 2-72 • --[no_]pch_verbose on page 2-72 • Precompiled header files on page 2-16 in the Compiler User Guide. 2.1.119 --[no_]using_std This option enables or disables implicit use of the std namespace when standard header files are included in C++. Note This option is provided only as a migration aid for legacy source code that does not conform to the C++ standard. Its use is not recommended. Mode This option is effective only if the source language is C++. 2-90 Copyright © 2007, 2010 ARM Limited. All rights reserved. ARM DUI 0348A Non-Confidential
Compiler Command-line Options Default The default is --no_using_std. See also • Namespaces on page 5-16. 2.1.120 --[no_]vectorize This option enables or disables the generation of NEON vector instructions directly from C or C++ code. Default The default is --no_vectorize. Restrictions The following options must be specified for loops to vectorize: --cpu=name -Otime -Onum Target processor must have NEON capability. Type of optimization to reduce execution time. Level of optimization. One of the following must be used: • -O2 High optimization. This is the default. • -O3 Maximum optimization. Note NEON is an implementation of the ARM Advanced Single Instruction, Multiple Data (SIMD) extension. A separate FLEXnet license is needed to enable the use of vectorization. Example armcc --vectorize --cpu=Cortex-A8 -O3 -Otime -c file.c See also • --cpu=name on page 2-15 • -Onum on page 2-66 • -Otime on page 2-69 ARM DUI 0348A Copyright © 2007, 2010 ARM Limited.
