+Subject: [PATCH 2/9] cmd/go: make content-based hash generation less pedantic
+
+Upstream-Status: Inappropriate [OE specific]
+
+Go 1.10's build tool now uses content-based hashes to
+determine when something should be built or re-built.
+This same mechanism is used to maintain a built-artifact
+cache for speeding up builds.
+
+However, the hashes it generates include information that
+doesn't work well with OE, nor with using a shared runtime
+library.
+
+First, it embeds path names to source files, unless
+building within GOROOT. This prevents the building
+of a package in GOPATH for later staging into GOROOT.
+
+This patch adds support for the environment variable
+GOPATH_OMIT_IN_ACTIONID. If present, path name
+embedding is disabled.
+
+Second, if cgo is enabled, the build ID for cgo-related
+packages will include the current value of the environment
+variables for invoking the compiler (CC, CXX, FC) and
+any CGO_xxFLAGS variables. Only if the settings used
+during a compilation exactly match, character for character,
+the values used for compiling runtime/cgo or any other
+cgo-enabled package being imported, will the tool
+decide that the imported package is up-to-date.
+
+This is done to help ensure correctness, but is overly
+simplistic and effectively prevents the reuse of built
+artifacts that use cgo (or shared runtime, which includes
+runtime/cgo).
+
+This patch filters out all compiler flags except those
+beginning with '-m'. The default behavior can be restored
+by setting the CGO_PEDANTIC environment variable.
+
+Adapted to Go 1.13 from patches originally submitted to
+the meta/recipes-devtools/go tree by
+Matt Madison <matt@madison.systems>.

+
+Upstream-Status: Inappropriate [OE specific]
+
+Change the dist tool to allow for OE-style cross-
+and cross-canadian builds:
+
+ - command flags --host-only and --target only are added;
+ if one is present, the other changes mentioned below
+ take effect, and arguments may also be specified on
+ the command line to enumerate the package(s) to be
+ built.
+
+ - for OE cross builds, go_bootstrap is always built for
+ the current build host, and is moved, along with the supporting
+ toolchain (asm, compile, etc.) to a separate 'native_native'
+ directory under GOROOT/pkg/tool.
+
+ - go_bootstrap is not automatically removed after the build,
+ so it can be reused later (e.g., building both static and
+ shared runtime).
+
+Note that for --host-only builds, it would be nice to specify
+just the "cmd" package to build only the go commands/tools,
+the staleness checks in the dist tool will fail if the "std"
+library has not also been built. So host-only builds have to
+build everything anyway.

+Subject: [PATCH 7/9] cmd/go: make GOROOT precious by default
+
+Upstream-Status: Inappropriate [OE specific]
+
+The go build tool normally rebuilds whatever it detects is
+stale. This can be a problem when GOROOT is intended to
+be read-only and the go runtime has been built as a shared
+library, since we don't want every application to be rebuilding
+the shared runtime - particularly in cross-build/packaging
+setups, since that would lead to 'abi mismatch' runtime errors.
+
+This patch prevents the install and linkshared actions from
+installing to GOROOT unless overridden with the GOROOT_OVERRIDE
+environment variable.
+
+Adapted to Go 1.13 from patches originally submitted to
+the meta/recipes-devtools/go tree by
+Matt Madison <matt@madison.systems>.
