Compiler Command-line Options 2.1 Command-line options This section lists the command-line options supported by the compiler in alphabetical order. 2.1.1 -Aopt This option specifies command-line options to pass to the assembler when it is invoked by the compiler to assemble either .s input files or embedded assembly language functions. Syntax -Aopt Where: opt is a command-line option to pass to the assembler. Note Some compiler command-line options are passed to the assembler automatically whenever it is invoked by the compiler. For example, if the option --cpu is specified on the compiler command line, then this option is passed to the assembler whenever it is invoked to assemble .s files or embedded assembler. To see the compiler command-line options passed by the compiler to the assembler, use the compiler command-line option -A--show_cmdline. Example armcc -A--predefine="NEWVERSION SETL {TRUE}" main.c Restrictions If an unsupported option is passed through using -A, an error is generated. See also • --cpu=name on page 2-30 • -Lopt on page 2-79 • --show_cmdline on page 2-116. 2-2 Copyright © 2007-2010 ARM. All rights reserved. ARM DUI 0348C Non-Confidential, ID101213
Compiler Command-line Options 2.1.2 --allow_null_this, --no_allow_this These options allow and disallow null this pointers in C++. Usage Allowing null this pointers gives well-defined behavior when a nonvirtual member function is called on a null object pointer. Disallowing null this pointers enables the compiler to perform optimizations, and conforms with the C++ standard. Default The default is --no_allow_null_this. See also • --gnu_defaults on page 2-68. 2.1.3 --alternative_tokens, --no_alternative_tokens This option enables or disables the recognition of alternative tokens in C and C++. Usage In C and C++, use this option to control recognition of the digraphs. In C++, use this option to control recognition of operator keywords, for example, and and bitand. Default The default is --alternative_tokens. 2.1.4 --anachronisms, --no_anachronisms This option enables or disables anachronisms in C++. Mode This option is effective only if the source language is C++. Default The default is --no_anachronisms. ARM DUI 0348C Copyright © 2007-2010 ARM.
