/arch (ARM)

Specifies the architecture for code generation on ARM. These switches apply to the ARM targeting version of the compiler. For more information on /arch for other target architectures, see /arch (ARM64), /arch (x64), and /arch (x86)

Syntax

/arch:[ARMv7VE|VFPv4]

Arguments

/arch:ARMv7VE
Enables the use of ARMv7VE Virtualization Extensions instructions.

/arch:VFPv4
Enables the use of ARM VFPv4 instructions. If this option isn't specified, VFPv3 is the default.

Remarks

The _M_ARM_FP macro (for ARM only) indicates which, if any, /arch compiler option was used. For more information, see Predefined macros.

When you use /clr to compile, /arch has no effect on code generation for managed functions. /arch only affects code generation for native functions.

To set the /arch:ARMv7VE or /arch:VFPv4 compiler option in Visual Studio

  1. Open the Property Pages dialog box for the project. For more information, see Set C++ compiler and build properties in Visual Studio.

  2. Select the Configuration Properties > C/C++ > Command Line property page.

  3. In the Additional options box, add /arch:ARMv7VE or /arch:VFPv4.
