To make the vx-insn.h more versatile avoid cpp preprocessor macros
and allow to use plain numbers for vector and general purpose register
operands. With that you can emit an .include from a C file into the
assembler text and then use the vx-insn macros in inline assemblies.

For example:

asm (".include \"asm/vx-insn.h\"");

static inline void xor_vec(int x, int y, int z)
{
	asm volatile("VX %0,%1,%2"
		     : : "i" (x), "i" (y), "i" (z));
}
