David Chase 612da32fb5 [release-branch.go1.20] cmd/compile: in expandCalls, move all arg marshalling into call block
For aggregate-typed arguments passed to a call, expandCalls
decomposed them into parts in the same block where the value
was created.  This is not necessarily the call block, and in
the case where stores are involved, can change the memory
leaving that block, and getting that right is problematic.

Instead, do all the expanding in the same block as the call,
which avoids the problems of (1) not being able to reorder
loads/stores across a block boundary to conform to memory
order and (2) (incorrectly, not) exposing the new memory to
consumers in other blocks.  Putting it all in the same block
as the call allows reordering, and the call creates its own
new memory (which is already dealt with correctly).

Fixes #62056.
Updates #61992.

README.md

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.
