David Chase 90ec257735 cmd/compile: make the stack allocator more careful about register args.
Assignment between input parameters causes them to have more than
one "Name", and running this backwards from names to values can end
up confusing (conflating) parameter spill slots.

Around 105a6e9518, this cases a stack overflow running
go test -race encoding/pem
because two slice parameters spill (incorrectly) into the same
stack slots (in the AB?I-defined parameter spill area).

This also tickles a failure in cue, which turned out to be
easier to isolate.

Fixes #45851.
Updates #40724.

zerodivide.go

The test directory contains tests of the Go tool chain and runtime. It includes black box tests, regression tests, and error output tests. They are run as part of all.bash.

To run just these tests, execute:

../bin/go run run.go

To run just tests from specified files in this directory, execute:

../bin/go run run.go -- file1.go file2.go ...

Standard library tests should be written as regular Go tests in the appropriate package.

The tool chain and runtime also have regular Go tests in their packages. The main reasons to add a new test to this directory are:

  • it is most naturally expressed using the test runner; or
  • it is also applicable to gccgo and other Go tool chains.
