[LLVMdev] The target independence of IR

[Hao Wang]

Hi,

Can anyone help me understand that LLVM IR has "target independence" ?

1. When we talk about "target", we mean something like Instruction Set
Architecture ?

2. The front-end may generate IR code such as x86_fp80, so the IR is
actually not fully target-independent? It contains information about the
target, and the front-end should also be aware of this?

Thank you!

Hao
