[LLVMdev] where are my phi-nodes?

[Maarten Faddegon]

Hi,

I am interested in SSA and read llvm uses SSA in its ir. I decided to write a simple program and compile it with llvm to the human readable assembly language representation of the ir. I expected phi nodes all over the place. However, I could not find a single one! Could you tell my why that is so?

I compiled with "llvm-gcc -emit-llvm test.c -S -o test.ll". Attached to this message are the source and the resulting ll output.

Thanks in advance,
