Integer constant propagation #18

Closed envp closed 6 years ago

envp commented 6 years ago

TODO

Cases considered

[x] Assignment to int types
[x] <UNRESOLVED> when passed to foo(int*)
[x] <UNRESOLVED> when passed to foo(int&)
[x] const qualified pointers and references must be skipped

envp commented 6 years ago

Update: Only compound assignment operators remain for this (not sure if clang will allow this because it considers XValues as side-effects that won't be evaluated as RValues)

Alternatively, since the common operations for most numeric types will be the same, shall I modify this PR to cover all numeric types instead of just integral ones?
