intrinsic

Hi,all.
I’ve been reading the llvm source code for some days.
Here is my problem:
what does instrinsic / intrinsic function really means?

Are these “the function belong to llvm and just belong to llvm”?

Thanks.

like gcc built-in func.

  You probably need to look at http://llvm.org/docs/ExtendingLLVM.html.
Simply put, when you want to extend LLVM IR, say adding a new LLVM
instruction, you have better try to add a intrinsic function [1] which has
the same effect as the instruction you want to add.

  I don't think they are the same as GCC built-in.

So much Thanks!!!
I’ve read your articles about llvm and qemu when I started to research s2e(It contains qemu klee llvm).Your views are very helpful to me!
Best wishes!
