Compiler Command-line Options } result *= n--; return result; Compiling this code with the options --vectorize --cpu=Cortex-A8 -O3 -Otime --diag_warning=optimizations generates optimization warning messages. See also • --diag_suppress=optimizations on page 2-47 • --diag_warning=tag[,tag,...] on page 2-48 • -Onum on page 2-96 • -Otime on page 2-99. 2.1.55 --dllexport_all, --no_dllexport_all This option enables you to control symbol visibility when building DLLs. Default The default is --no_dllexport_all. Usage Use the option --dllexport_all to mark all extern definitions as __declspec(dllexport). See also • --apcs=qualifer...qualifier on page 2-4 • __declspec(dllexport) on page 4-24. 2.1.56 --dllimport_runtime, --no_dllimport_runtime This option enables you to control symbol visibility when using the runtime library as a shared library. Default The default is --no_dllimport_runtime. Usage Use the option --dllimport_runtime to mark: • all builtin symbols as __declspec(dllimport) 2-50 Copyright © 2007-2010 ARM. All rights reserved.

Compiler Command-line Options • RunTime Type Information (RTTI) generated in the cpprt runtime libraries for import • any optimized printf() and __hardfp_ functions for import, provided that the original function is marked as __declspec(dllimport). See also • --guiding_decls, --no_guiding_decls on page 2-70 • --rtti, --no_rtti on page 2-114 • __declspec(dllimport) on page 4-26. 2.1.57 --dollar, --no_dollar This option instructs the compiler to accept or reject dollar signs, $, in identifiers. Default If the options --strict or --strict_warnings are specified, the default is --no_dollar. Otherwise, the default is --dollar. See also • Dollar signs in identifiers on page 3-13 • --strict, --no_strict on page 2-119. 2.1.58 --dwarf2 This option instructs the compiler to use DWARF 2 debug table format. Default The compiler assumes --dwarf3 unless --dwarf2 is explicitly specified. See also • --dwarf3. 2.1.59 --dwarf3 This option instructs the compiler to use DWARF 3 debug table format. Default The compiler assumes --dwarf3 unless --dwarf2 is explicitly specified. ARM DUI 0348C Copyright © 2007-2010 ARM. All rights reserved. 2-51 ID101213 Non-Confidential,
