Specifies the architecture for code generation on ARM. See also /arch (x86) and /arch (x64).

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 is not 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.
