Helps to provide 1:1 build experience between git-managed and tarball sources. Signed-off-by: onur-ozkan <work@onurozkan.dev>
this prepares the code structure for adding logical edges to the graph next
Instead of materializing `Locations::All` constraints as physical edges at all the points in the CFG, we record them as logical edges and only materialize them during traversal as successors for a given node. This fixes the slowness/hang in the `saturating-float-casts.rs` test.

Mention the IEEE function by name and create a doc alias of the same.
const-eval: detect more pointers as definitely not-null This fixes rust-lang#133523 by making the `scalar_may_be_null` check smarter: for instance, an odd offset in any 2-aligned allocation can never be null, even if it is out-of-bounds. More generally, if an allocation with unknown base address B is aligned to alignment N, and a pointer is at offset X inside that allocation, then we know that `(B + X) mod N = B mod N + X mod N = X mod N`. Since `0 mod N` is definitely 0, if we learn that `X mod N` is *not* 0 we can deduce that `B + X` is not 0. This is immediately visible on stable, via `ptr.is_null()` (and, more subtly, by not raising a UB error when such a pointer is used somewhere that a non-null pointer is required). Therefore nominating for `@rust-lang/lang.`
…kh726 Encode constraints that hold at all points as logical edges in location-sensitive polonius Currently, with the full setup in rust-lang#134980 (but is from rust-lang#134268), the polonius location-sensitive analysis converts `Locations::All` typeck constraints as edges at all points in the CFG. This was temporary. There's a FIXME about that already, and this PR implements it: we now use the constraints that hold at all points during traversal instead of eagerly materializing them as physical edges. Another easy one `@jackh726.` This fixes the slowness that was happening on the big CFG from the `saturating-float-casts` test (because of its 12M materialized edges) without, AFAICT, simply moving this overhead to traversal: materializing the logical edges is done on-demand. r? `@jackh726` (no rush either)
Run clippy for rustc_codegen_gcc on CI Requested on [Zulip](https://rust-lang.zulipchat.com/#narrow/channel/242791-t-infra/topic/Run.20clippy.20for.20rustc_codegen_gcc.20in.20the.20Rust.20CI). Opening as a draft, since it's not clear which rules should be applied to it. r? `@ghost`
