MC/DC's reliance on the existing branch coverage types is making it much harder to improve branch coverage.
This clears the way for larger changes to how branches are handled by the coverage instrumentor, in order to support branch coverage for more language constructs.
checked_ilog: improve performance Addresses rust-lang#115874. (This PR replicates the original rust-lang#115875, which I accidentally closed by deleting my forked repository...)
…-obk [cleanup] [llvm backend] Prevent creating the same `Instance::mono` multiple times Just a little thing I came across while going through the code. r? ```@oli-obk```
…, r=oli-obk Stop taking `ParamTy`/`ParamConst`/`EarlyParamRegion`/`AliasTy` by ref It's unnecessary and is annoying when we have it by value.
coverage: Prepare for improved branch coverage When trying to rebase my new branch coverage work (including rust-lang#124154) on top of the introduction of MC/DC coverage (rust-lang#123409), I found it a lot harder than anticipated. With the benefit of hindsight, the branch coverage code and MC/DC code have become more interdependent than I'm happy with. This PR therefore disentangles them a bit, so that it will be easier for both areas of code to evolve independently without interference. --- This PR also includes a few extra branch coverage tests that I had sitting around from my current branch coverage work. They mostly just demonstrate that certain language constructs listed in rust-lang#124118 currently don't have branch coverage support. ``@rustbot`` label +A-code-coverage
…e, r=dtolnay Stabilize generic `NonZero`. Tracking issue: rust-lang#120257 r? `@dtolnay`
…read-ice, r=oli-obk Improve ICE message for forbidden dep-graph reads. The new message mentions the main context that the ICE might occur in and it mentions the query/dep-node that is being read. cc rust-lang#123781, where this would have been helpful.
