959237e8d2 C++: Fix missing type for Phi nodes. 2023-03-02 22:48:10 +00:00
Mathias Vorreiter Pedersen
2963dc1cb1 C++: Include phi read nodes in SSA. 
There's a small fix to the mapping from 'global def -> use'.

Finally, this commit also accepts a test failure related to new missing
types for phi nodes. The fix for that is in the next commit.

1db24dd28d C++: Fix missing types. We now assign the node corresponding to **p 
an `UnknownType`.
 2023-02-27 14:57:36 +00:00
Mathias Vorreiter Pedersen
4e16bb65e3 C++: Accept test changes. Because we now allocate _three_ indirect nodes 
for a value of type `void*` (i.e., `p`, `*p` and `**p`) we need to decide
on a type for the `**p` value. We will do this in the next commit.

09df318e9e C++: Also track flow out of indirect sources. 2023-02-27 14:57:35 +00:00
Mathias Vorreiter Pedersen
a806569b5f C++: The next commit is going to track flow out of both direct and indirect sources. This means we'll get a lot of duplication since there'll be flow from indirect source -> indirect sink and direct source -> direct sink (which both map to the same expressions). This commit changes the testing so that we only report a duplication when they're at different locations. 2023-02-27 14:57:35 +00:00
