Compiler Command-line Options Example typedef enum { red, white, blue } tricolor; inline tricolor operator++(tricolor c, int) { int i = static_cast(c) + 1; return static_cast(i); } void foo(void) { tricolor c = red; c++; // okay ++c; // anachronism } Compiling this code with the option --anachronisms generates a warning message. Compiling this code without the option --anachronisms generates an error message. See also • --cpp on page 2-30 • --strict, --no_strict on page 2-119 • --strict_warnings on page 2-120 • Anachronisms on page 5-14. 2.1.5 --apcs=qualifer...qualifier This option controls interworking and position independence when generating code. By specifying qualifiers to the --apcs command-line option, you can define the variant of the Procedure Call Standard for the ARM architecture (AAPCS) used by the compiler. Syntax --apcs=qualifer...qualifier Where qualifier...qualifier denotes a list of qualifiers. There must be: • at least one qualifier present • no spaces separating individual qualifiers in the list. 2-4 Copyright © 2007-2010 ARM. All rights reserved. ARM DUI 0348C Non-Confidential, ID101213
Compiler Command-line Options Each instance of qualifier must be one of: /interwork, /nointerwork /ropi, /noropi /rwpi, /norwpi /fpic, /nofpic Generates code with or without ARM/Thumb interworking support. The default is /nointerwork, except for ARMv6 and later where the default is /interwork. Enables or disables the generation of Read-Only Position-Independent (ROPI) code. The default is /noropi. /[no]pic is an alias for /[no]ropi. Enables or disables the generation of Read/Write Position-Independent (RWPI) code. The default is /norwpi. /[no]pid is an alias for /[no]rwpi. Enables or disables the generation of read-only position-independent code where relative address references are independent of the location where your program is loaded. Note You can alternatively specify multiple qualifiers. For example, --apcs=/nointerwork/noropi/norwpi is equivalent to --apcs=/nointerwork --apcs=noropi/norwpi. Default If you do not specify an --apcs option, the compiler assumes --apcs=/nointerwork/noropi/norwpi/nofpic. Usage /interwork, /nointerwork By default, code is generated: • without interworking support, that is /nointerwork, unless you specify a --cpu option that corresponds to architecture ARMv5T or later • with interworking support, that is /interwork, on ARMv5T and later. Interworking happens automatically on ARMv5T and later ARM architectures. /ropi, /noropi If you select the /ropi qualifier to generate ROPI code, the compiler: • addresses read-only code and data PC-relative ARM DUI 0348C Copyright © 2007-2010 ARM.
