[llvm-dev] DemotePHIToStack + invoke

[Wehrli Johan via llvm-dev]

Hi,

When I was looking into the code of DemotePhiToStack, I noticed that the invokeInst are not handled.

Can someone tell me why this is not the case, if there are tricky case which I have not thought?

I tried to create something and it seems to work but I want some advice.

Long story short, I create a new basic block between the invoke and the normalDest.

In this new basic block I save the result of the invoke and replace all of its uses, then, I update the incoming block into the phi node.

I run the test of CryptoPP and openssl and it seems to work.

Greetings,

Johan
