[llvm-dev] minimal C code that would generate IR code using phi

[Peng Yu via llvm-dev]

Hi,

I am trying to understand phi better. I know what it means.

https://en.wikipedia.org/wiki/Static_single_assignment_form

But when I tried to create a minimal code using if-else with
unbalanced statements to change a variable in C, it still did not
generate IR code using phi.

Does anybody have a minimal C code that would generate IR code using
phi? Thanks.
