Lynn Boger ebe49f98c8 cmd/compile: inline constant sized memclrNoHeapPointers calls on PPC64 Update the function isInlinableMemclr for ppc64 and ppc64le to enable inlining for the constant sized cases < 512. Larger cases can use dcbz which performs better but requires alignment checking so it is best to continue using memclrNoHeapPointers for those cases. Results on p10: MemclrKnownSize1 2.07ns ± 0% 0.57ns ± 0% -72.59% MemclrKnownSize2 2.56ns ± 5% 0.57ns ± 0% -77.82% MemclrKnownSize4 5.15ns ± 0% 0.57ns ± 0% -89.00% MemclrKnownSize8 2.23ns ± 0% 0.57ns ± 0% -74.57% MemclrKnownSize16 2.23ns ± 0% 0.50ns ± 0% -77.74% MemclrKnownSize32 2.28ns ± 0% 0.56ns ± 0% -75.28% MemclrKnownSize64 2.49ns ± 0% 0.72ns ± 0% -70.95% MemclrKnownSize112 2.97ns ± 2% 1.14ns ± 0% -61.72% MemclrKnownSize128 4.64ns ± 6% 2.45ns ± 1% -47.17% MemclrKnownSize192 5.45ns ± 5% 2.79ns ± 0% -48.87% MemclrKnownSize248 4.51ns ± 0% 2.83ns ± 0% -37.12% MemclrKnownSize256 6.34ns ± 1% 3.58ns ± 0% -43.53% MemclrKnownSize512 3.64ns ± 0% 3.64ns ± 0% -0.03% MemclrKnownSize1024 4.73ns ± 0% 4.73ns ± 0% +0.01% MemclrKnownSize4096 17.1ns ± 0% 17.1ns ± 0% +0.07% MemclrKnownSize512KiB 2.12µs ± 0% 2.12µs ± 0% ~ (all equal) Change-Id: If1abf5749f4802c64523a41fe0058bd144d0ea46 Reviewed-on: https://go-review.googlesource.com/c/go/+/464340 Run-TryBot: Lynn Boger <laboger@linux.vnet.ibm.com> Reviewed-by: Jakub Ciolek <jakub@ciolek.dev> Reviewed-by: Archana Ravindar <aravind5@in.ibm.com> Reviewed-by: Ian Lance Taylor <iant@google.com> Reviewed-by: Carlos Eduardo Seo <carlos.seo@linaro.org> TryBot-Result: Gopher Robot <gobot@golang.org> Reviewed-by: Than McIntosh <thanm@google.com>		2023-02-23 18:57:27 +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 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.
