match lowering: make false edges more precise

When lowering match expressions, we add false edges to hide details of the lowering from borrowck. Morally we pretend we're testing the patterns (and guards) one after the other in order. See the tests for examples. Problem is, the way we implement this today is too coarse for deref patterns.

In deref patterns, a pattern like `deref [1, x]` matches on a `Vec` by creating a temporary to store the output of the call to `deref()` and then uses that to continue matching. Here the pattern has a binding, which we set up after the pre-binding block. Problem is, currently the false edges tell borrowck that the pre-binding block can be reached from a previous arm as well, so the `deref()` temporary may not be initialized. This triggers an error when we try to use the binding `x`.

We could call `deref()` a second time, but this opens the door to soundness issues if the deref impl is weird. Instead in this PR I rework false edges a little bit.

What we need from false edges is a (fake) path from each candidate to the next, specifically from candidate C's pre-binding block to next candidate D's pre-binding block. Today, we link the pre-binding blocks directly. In this PR, I link them indirectly by choosing an earlier node on D's success path. Specifically, I choose the earliest block on D's success path that doesn't make a loop (if I chose e.g. the start block of the whole match (which is on the success path of all candidates), that would make a loop). This turns out to be rather straightforward to implement.

This folder contains tests for MIR optimizations.

The mir-opt test format emits MIR to extra files that you can automatically update by specifying --bless on the command line (just like ui tests updating .stderr files).

--blessable test format

By default 32 bit and 64 bit targets use the same dump files, which can be problematic in the presence of pointers in constants or other bit width dependent things. In that case you can add

// EMIT_MIR_FOR_EACH_BIT_WIDTH

to your test, causing separate files to be generated for 32bit and 64bit systems.

Unit testing

If you are only testing the behavior of a particular mir-opt pass on some specific input (as is usually the case), you should add

// unit-test: PassName

to the top of the file. This makes sure that other passes don't run which means you'll get the input you expected and your test won't break when other code changes.

Emit a diff of the mir for a specific optimization

This is what you want most often when you want to see how an optimization changes the MIR.

// EMIT_MIR $file_name_of_some_mir_dump.diff

Emit mir after a specific optimization

Use this if you are just interested in the final state after an optimization.

// EMIT_MIR $file_name_of_some_mir_dump.after.mir

Emit mir before a specific optimization

This exists mainly for completeness and is rarely useful.

// EMIT_MIR $file_name_of_some_mir_dump.before.mir

FileCheck directives

The LLVM FileCheck tool is used to verify the contents of output MIR against CHECK directives present in the test file. This works on the runtime MIR, generated by --emit=mir, and not on the output of a individual passes.

Use // skip-filecheck to prevent FileCheck from running.

To check MIR for function foo, start with a // CHECK-LABEL fn foo( directive.

{{regex}} syntax allows to match regex.

[[name:regex]] syntax allows to bind name to a string matching regex, and refer to it as [[name]] in later directives, regex should be written not to match a leading space. Use [[my_local:_.*]] to name a local, and [[my_bb:bb.*]] to name a block.

Documentation for FileCheck is available here: https://www.llvm.org/docs/CommandGuide/FileCheck.html
