I read LLVM manual, and have a question in the LLVM IR.
The IR is low-level SSA based instruction set.
I want to know what the difference between the LLVM IR and SSA form?
They are same, similar to tree-ssa of GCC convertion GIMPLE tree to SSA and convert back when optimizations finish?
or just attach the SSA info in the LLVM IR?
Thanks for your feedback.
