recipes-devtools/go/go/0001-cmd-go-make-content-based-hash-generation-less-pedan.patch

+From 51c04a9a19dec5a48fa0f38324dc2480b7a859e4 Mon Sep 17 00:00:00 2001
+From: Khem Raj <raj.khem@gmail.com>
+Date: Sat, 22 Feb 2025 03:24:48 -0800
+Subject: [PATCH 01/11] cmd/go: make content-based hash generation less
+ pedantic
+
+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.
+
+Upstream-Status: Inappropriate [OE specific]

recipes-devtools/go/go/0005-cmd-dist-separate-host-and-target-builds.patch

+From 12bf824f8b7e85f05434aa00e866e883a551aaeb Mon Sep 17 00:00:00 2001
+From: Alex Kube <alexander.j.kube@gmail.com>
+Date: Fri, 28 Feb 2025 19:09:17 -0800
+Subject: [PATCH 05/11] cmd/dist: separate host and target builds
+
+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.
+
+Adapted to Go 1.13 from patches originally submitted to
+the meta/recipes-devtools/go tree by
+Matt Madison <matt@madison.systems>.
+
+Rework the patch to avoid identation, it breaks formatting rules but
+makes the changes more obvious and maintainable.

+Subject: [PATCH 06/11] cmd/go: make GOROOT precious by default
+
+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>.
+
+Upstream-Status: Inappropriate [OE specific]
