Compiler Command-line Options Note Do not rely on the implementation details of these optimizations, because they might change in future releases. Default If you do not specify -Onum, the compiler assumes -O2. See also • --autoinline, --no_autoinline on page 2-17 • --debug, --no_debug on page 2-37 • --forceinline on page 2-58 • --fpmode=model on page 2-59 • --inline, --no_inline on page 2-75 • --ltcg on page 2-88 • --multifile, --no_multifile on page 2-92 • -Ospace on page 2-99 • -Otime on page 2-99 • Optimizing code on page 5-2 in the Compiler User Guide. 2.1.121 --old_specializations, --no_old_specializations This option controls the acceptance of old-style template specializations in C++. Old-style template specializations do not use the template syntax. Note The option --old_specializations 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++. Default The default is --no_old_specializations. 2-98 Copyright © 2007-2010 ARM. All rights reserved.

Compiler Command-line Options 2.1.122 -Ospace This option instructs the compiler to perform optimizations to reduce image size at the expense of a possible increase in execution time. Use this option if code size is more critical than performance. For example, when the -Ospace option is selected, large structure copies are done by out-of-line function calls instead of inline code. If required, you can compile the time-critical parts of your code with -Otime, and the rest with -Ospace. Default If you do not specify either -Ospace or -Otime, the compiler assumes -Ospace. See also • -Otime • -Onum on page 2-96 • #pragma Onum on page 4-67 • #pragma Ospace on page 4-68 • #pragma Otime on page 4-68. 2.1.123 -Otime This option instructs the compiler to perform optimizations to reduce execution time at the expense of a possible increase in image size. Use this option if execution time is more critical than code size. If required, you can compile the time-critical parts of your code with -Otime, and the rest with -Ospace. Default If you do not specify -Otime, the compiler assumes -Ospace. Example When the -Otime option is selected, the compiler compiles: while (expression) body; as: ARM DUI 0348C Copyright © 2007-2010 ARM. All rights reserved. 2-99 ID101213 Non-Confidential,
