[LLVMdev] what's meaning of the last field of an LLVM intrinsic instrucation

[zhi chen]

The intrinsic instructions always have an number in the end, what's meaning
of it?

For example,   %2 = call <2 x double> @llvm.x86.sse2.sqrt.pd(<2 x double>
%1) #2

What does this #2 mean? Can I ignore it when I create the instruction?
Thanks.

Best,
Zhi
