Paul E. Murphy 6ce543d137 [release-branch.go1.19] cmd/compile: on PPC64, fix sign/zero extension when masking 
This backport required manual cleanup as go1.20 combined the
ANDCCconst and ANDconst opcodes into one. Similarly, CL 456736
introduced a suble bug by using (Select1 (ANDCCconst ...)). This
usually worked because the same rule quietly changes the type
of the newly created ANDCCconst to a tuple. This change exposed
the bug, so fix it too.

(ANDconst [y] (MOV.*reg x)) should only be merged when zero
extending. Otherwise, sign bits are lost on negative values.

(ANDconst [0xFF] (MOVBreg x)) should be simplified to a zero
extension of x. Likewise for the MOVHreg variant.

Fixes #61319

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.
