Compiler Command-line Options 2.1.168 --vsn This option displays the version information and the license details. See also • --help on page 2-71. 2.1.169 -W This option instructs the compiler to suppress all warning messages. See also • --brief_diagnostics, --no_brief_diagnostics on page 2-19 • --diag_error=tag[,tag,...] on page 2-44 • --diag_remark=tag[,tag,... ] on page 2-45 • --diag_style={arm|ide|gnu} on page 2-46 • --diag_suppress=tag[,tag,...] on page 2-47 • --diag_warning=tag[,tag,...] on page 2-48 • --errors=filename on page 2-53 • --remarks on page 2-111 • --wrap_diagnostics, --no_wrap_diagnostics on page 2-137 2.1.170 --wchar, --no_wchar This option permits or forbids the use of wchar_t. It does not necessarily fault declarations, providing they are unused. Usage Use this option to create an object file that is independent of wchar_t size. Restrictions If --no_wchar is specified: • wchar_t fields in structure declarations are faulted by the compiler, regardless of whether or not the structure is used • wchar_t in a typedef is faulted by the compiler, regardless of whether or not the typedef is used. 2-134 Copyright © 2007-2010 ARM.

Compiler Command-line Options Default The default is --wchar. See also • --wchar16 • --wchar32. 2.1.171 --wchar16 This option changes the type of wchar_t to unsigned short. Selecting this option modifies both the type of the defined type wchar_t in C and the type of the native type wchar_t in C++. It also affects the values of WCHAR_MIN and WCHAR_MAX. Default The compiler assumes --wchar16 unless --wchar32 is explicitly specified. See also • --wchar, --no_wchar on page 2-134 • --wchar32 • Predefined macros on page 4-198. 2.1.172 --wchar32 This option changes the type of wchar_t to unsigned int. Selecting this option modifies both the type of the defined type wchar_t in C and the type of the native type wchar_t in C++. It also affects the values of WCHAR_MIN and WCHAR_MAX. Default The compiler assumes --wchar16 unless --wchar32 is explicitly specified, or unless you specify an ARM Linux configuration file on the command line. Specifying an ARM Linux configuration file on the command line turns --wchar32 on. See also • --arm_linux_config_file=path on page 2-10 • --arm_linux_configure on page 2-12 • --signed_bitfields, --unsigned_bitfields on page 2-116 • --wchar, --no_wchar on page 2-134 ARM DUI 0348C Copyright © 2007-2010 ARM.
