Compiler Command-line Options • --diag_warning=tag[,tag,...] on page 2-48 • --remarks on page 2-111 • -W on page 2-134 • --wrap_diagnostics, --no_wrap_diagnostics on page 2-137 • Chapter 6 Diagnostic Messages in the Compiler User Guide. 2.1.64 --exceptions, --no_exceptions This option enables or disables exception handling. In C++, the --exceptions option enables the use of throw and try/catch, causes function exception specifications to be respected, and causes the compiler to emit unwinding tables to support exception propagation at runtime. In C++, when the --no_exceptions option is specified, throw and try/catch are not permitted in source code. However, function exception specifications are still parsed, but most of their meaning is ignored. In C, the behavior of code compiled with --no_exceptions is undefined if an exception is thrown through the compiled functions. You must use --exceptions, if you want exceptions to propagate correctly though C functions. Default The default is --no_exceptions. However, if you specify an ARM Linux configuration file on the command line and you use --translate_g++, the default changes to --exceptions. See also • --arm_linux_config_file=path on page 2-10 • --arm_linux_configure on page 2-12 • --exceptions_unwind, --no_exceptions_unwind. 2.1.65 --exceptions_unwind, --no_exceptions_unwind This option enables or disables function unwinding for exception-aware code. This option is only effective if --exceptions is enabled. When you use --no_exceptions_unwind and --exceptions then no exception can propagate through the compiled functions. std::terminate is called instead. 2-54 Copyright © 2007-2010 ARM.

Compiler Command-line Options Default The default is --exceptions_unwind. See also • --exceptions, --no_exceptions on page 2-54 • Function unwinding at runtime on page 5-18. 2.1.66 --export_all_vtbl, --no_export_all_vtbl This option controls how dynamic symbols are exported in C++. Mode This option is effective only if the source language is C++. Default The default is --no_export_all_vtbl. Usage Use the option --export_all_vtbl to export all virtual function tables and RTTI for classes with a key function. A key function is the first virtual function of a class, in declaration order, that is not inline, and is not pure virtual. Note You can disable export for specific classes by using __declspec(notshared). See also • __declspec(notshared) on page 4-29. 2.1.67 --export_defs_implicitly, --no_export_defs_implicitly This option controls how dynamic symbols are exported. Default The default is --no_export_defs_implicitly. ARM DUI 0348C Copyright © 2007-2010 ARM. All rights reserved. 2-55 ID101213 Non-Confidential,
