Cherry Zhang f5efa5a313 cmd/compile: load results into registers on open defer return path
When a function panics then recovers, it needs to return to the
caller with named results having the correct values. For
in-register results, we need to load them into registers at the
defer return path.

For non-open-coded defers, we already generate correct code, as
the defer return path is part of the SSA CFG and contains the
instructions that are the same as an ordinary return statement,
including putting the results to the right places.

For open-coded defers, we have a special code generation that
emits a disconnected block that currently contains only the
deferreturn call and a RET instruction. It leaves the result
registers unset. This CL adds instructions that load the result
registers on that path.

Updates #40724.

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.
