thepudds 988a20c8c5 cmd/compile/internal/escape: evaluate any side effects when rewriting with literals 
CL 649035 and CL 649079 updated escape analysis to rewrite
certain operands in OMAKE and OCONVIFACE nodes from non-constant
expressions to basic literals that evaluate to the same value.

However, when doing that rewriting, we need to evaluate any
side effects prior to replacing the expression, which is what
this CL now does.

Issue #74379 reported a problem with OCONVIFACE nodes due to CL 649079.
CL 649035 has essentially the same issue with OMAKE nodes. To illustrate
that, we add a test for the OMAKE case in fixedbugs/issue74379b.go,
which fails without this change. To avoid introducing an unnecessary
temporary for OMAKE nodes, we also conditionalize the main work of
CL 649035 on whether the OMAKE operand is already an OLITERAL.

CL 649555 and CL 649078 were related changes that created read-only
global storage for composite literals used in an interface conversion.
This CL adds a test in fixedbugs/issue74379c.go to illustrate
that they do not have the same problem.

Updates #71359
Fixes #74379

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 test cmd/internal/testdir

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

../bin/go test cmd/internal/testdir -run='Test/(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.
