Subject: [PATCH 6/9] cmd/dist: separate host and target builds
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>.

Subject: [PATCH 8/9] cmd/go: Use GOBUILDMODE to set buildmode
Upstream-Status: Denied [upstream choose antoher solution: `17a256b
cmd/go: -buildmode=pie for android/arm']
While building go itself, the go build system does not support
to set `-buildmode=pie' from environment.
Add GOBUILDMODE to support it which make PIE executables the default
build mode, as PIE executables are required as of Yocto

From a13ae484e41139094505d2834437e9262a5315f7 Mon Sep 17 00:00:00 2001

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>.
