[cfg] rename iCFG to cfg in dotty files Summary: Not sure what an "iCFG" is but the dotty is only about CFGs anyway. Diff obtained by mass-`sed`. Reviewed By: sblackshear Differential Revision: D6324280 fbshipit-source-id: b7603bb

Sort nodes when printing cfg to dot file Summary: Currently cfg nodes are written into dot files in whatever order they appear in a hash table. This seems unnecessarily sensitive, so this diff sorts the nodes. Reviewed By: dulmarod Differential Revision: D4232377 fbshipit-source-id: a907cc6

[preanalysis] do not delay killing variables taken by reference Summary: Before, the liveness pre-analysis would place extra instructions in the CFG for either: 1. marking an `Ident.t` as dead, or 2. marking a `Pvar.t` as `= 0` But we have no way of marking pvars dead without setting them to 0. This is bad because setting pvars to 0 is not possible everywhere they are dead. Indeed, we only do it when we haven't seen their address being taken anyway. This prevents the following situation, recorded in our tests: ``` int address_taken() { int** x; int* y; int i = 7; y = &i; x = &y; // if we don't reason about taken addresses while adding nullify instructions, // we'll add // `nullify(y)` here and report a false NPE on the next line return **x; } ``` So we want to mark pvars as dead without nullifying them. This diff extends the `Remove_temps` SIL instruction to accept pvars as well, and so renames it to `ExitScope`. Reviewed By: da319 Differential Revision: D13102953 fbshipit-source-id: aa7f03a52

[SIL] change `variable_initialization()` builtin to a new auxiliary instruction Summary: Instead of emitting an ad-hoc builtin on variable declaration emit a new metadata instruction. This allows us to remove the code matching on that ad-hoc builtin that had to be inserted in several checkers. Inferbo & pulse used that information meaningfully and had to undergo some minor changes to cope with the new metada instruction.
