History

eric fang e0ceba8139 cmd/compile: enhance tighten pass for memory values [This is a roll-forward of CL 458755, which was reverted due to make.bash being broken on GOAMD64=v3. But it turned out that the problem was caused by wrong bswap/load rewrite rules, and it was fixed in CL 492616.] This CL enhances the tighten pass. Previously if a value has memory arg, then the tighten pass won't move it, actually if the memory state is consistent among definition and use block, we can move the value. This CL optimizes this case. This is useful for the following situation: b1: x = load(...mem) if(...) goto b2 else b3 b2: use(x) b3: some_op_not_use_x For the micro-benchmark mentioned in #56620, the performance improvement is about 15%. There's no noticeable performance change in the go1 benchmark. Fixes #56620 Change-Id: I36ea68bed384986cd3ae81cb9e6efe84bb213adc Reviewed-on: https://go-review.googlesource.com/c/go/+/492895 Reviewed-by: Keith Randall <khr@golang.org> TryBot-Result: Gopher Robot <gobot@golang.org> Reviewed-by: Heschi Kreinick <heschi@google.com> Reviewed-by: Keith Randall <khr@google.com> Run-TryBot: Eric Fang <eric.fang@arm.com>		2023-05-16 01:01:38 +00:00

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.
