Hi, Richard, Thanks a lot for your suggestion. Actually, I like this idea. My understanding of your suggestion is: 1. During gimplification phase: For each auto-variable that does not have an explicit initializer, insert the following initializer for it: X = DEFERRED_INIT (X, INIT) In

Re: How to traverse all the local variables that declared in the current routine?

Hi, Richard, Could you please comment on the following approach: Instead of adding the zero-initializer quite late at the pass “pass_expand”, we can add it as early as during gimplification. However, we will mark these new added zero-initializers as “artificial”. And passing this

How to traverse all the local variables that declared in the current routine?

Hi, Does gcc provide an iterator to traverse all the local variables that are declared in the current routine? If not, what’s the best way to traverse the local variables? Thanks. Qing
