+Android
+=======
+
+For details on developing Go for Android, see the documentation in the
+mobile subrepository:
+
+	https://github.com/golang/mobile
+
+To run the standard library tests, enable Cgo and use an appropriate
+C compiler from the Android NDK. For example,
+
+	CGO_ENABLED=1 \
+	GOOS=android \
+	GOARCH=arm64 \
+	CC_FOR_TARGET=$NDK/toolchains/llvm/prebuilt/linux-x86_64/bin/aarch64-linux-android21-clang \
+	./all.bash
+
+To run tests on the Android device, add the bin directory to PATH so the
+go tool can find the go_android_$GOARCH_exec wrapper generated by
+make.bash. For example, to run the go1 benchmarks
+
+	export PATH=$GOROOT/bin:$PATH
+	cd $GOROOT/test/bench/go1/
+	GOOS=android GOARCH=arm64 go test -bench=. -count=N -timeout=T
+

+An example of wrapping a C library in Go. This is the GNU
+multiprecision library gmp's integer type mpz_t wrapped to look like
+the Go package big's integer type Int.
+
+This is a syntactically valid Go program—it can be parsed with the Go
+parser and processed by godoc—but it is not compiled directly by gc.
+Instead, a separate tool, cgo, processes it to produce three output
+files.  The first two, 6g.go and 6c.c, are a Go source file for 6g and
+a C source file for 6c; both compile as part of the named package
+(gmp, in this example).  The third, gcc.c, is a C source file for gcc;
+it compiles into a shared object (.so) that is dynamically linked into
+any 6.out that imports the first two files.
+
+The stanza
+
+	// #include <gmp.h>
+	import "C"
+
+is a signal to cgo.  The doc comment on the import of "C" provides
+additional context for the C file.  Here it is just a single #include
+but it could contain arbitrary C definitions to be imported and used.
+
+Cgo recognizes any use of a qualified identifier C.xxx and uses gcc to
+find the definition of xxx.  If xxx is a type, cgo replaces C.xxx with
+a Go translation.  C arithmetic types translate to precisely-sized Go
+arithmetic types.  A C struct translates to a Go struct, field by
+field; unrepresentable fields are replaced with opaque byte arrays.  A
+C union translates into a struct containing the first union member and
+perhaps additional padding.  C arrays become Go arrays.  C pointers
+become Go pointers.  C function pointers become Go's uintptr.
+C void pointers become Go's unsafe.Pointer.
+
+For example, mpz_t is defined in <gmp.h> as:
+
+	typedef unsigned long int mp_limb_t;
+
+	typedef struct
+	{
+		int _mp_alloc;
+		int _mp_size;
+		mp_limb_t *_mp_d;
+	} __mpz_struct;
+
+	typedef __mpz_struct mpz_t[1];
+
+Cgo generates:
+
+	type _C_int int32
+	type _C_mp_limb_t uint64
+	type _C___mpz_struct struct {
+		_mp_alloc _C_int;
+		_mp_size _C_int;
+		_mp_d *_C_mp_limb_t;
+	}
+	type _C_mpz_t [1]_C___mpz_struct
+
+and then replaces each occurrence of a type C.xxx with _C_xxx.
+
+If xxx is data, cgo arranges for C.xxx to refer to the C variable,
+with the type translated as described above.  To do this, cgo must
+introduce a Go variable that points at the C variable (the linker can
+be told to initialize this pointer).  For example, if the gmp library
+provided
+
+	mpz_t zero;
+
+then cgo would rewrite a reference to C.zero by introducing
+
+	var _C_zero *C.mpz_t
+
+and then replacing all instances of C.zero with (*_C_zero).
+
+Cgo's most interesting translation is for functions.  If xxx is a C
+function, then cgo rewrites C.xxx into a new function _C_xxx that
+calls the C xxx in a standard pthread.  The new function translates
+its arguments, calls xxx, and translates the return value.
+
+Translation of parameters and the return value follows the type
+translation above except that arrays passed as parameters translate
+explicitly in Go to pointers to arrays, as they do (implicitly) in C.
+
+Garbage collection is the big problem.  It is fine for the Go world to
+have pointers into the C world and to free those pointers when they
+are no longer needed.  To help, the Go code can define Go objects
+holding the C pointers and use runtime.SetFinalizer on those Go objects.
+
+It is much more difficult for the C world to have pointers into the Go
+world, because the Go garbage collector is unaware of the memory
+allocated by C.  The most important consideration is not to
+constrain future implementations, so the rule is that Go code can
+hand a Go pointer to C code but must separately arrange for
+Go to hang on to a reference to the pointer until C is done with it.

+//    (concrete type / interface type).  This itab goes in hash bucket 0x111.
+// 2) The plugin adds that same itab again.  That makes a cycle in the itab

+// 3) The main binary then asks for the itab for *dynamodbstreamsevt.Event /
+//    json.Unmarshaler.  This itab happens to also live in bucket 0x111.
+//    The lookup code goes into an infinite loop searching for this itab.
+// The code is carefully crafted so that the two itabs are both from the
+// same bucket, and so that the second itab doesn't exist in
+// the itab hashmap yet (so the entire linked list must be searched).

+Go on iOS
+=========
+
+To run the standard library tests, run all.bash as usual, but with the compiler
+set to the clang wrapper that invokes clang for iOS. For example, this command runs
+ all.bash on the iOS emulator:
+
+	GOOS=ios GOARCH=amd64 CGO_ENABLED=1 CC_FOR_TARGET=$(pwd)/../misc/ios/clangwrap.sh ./all.bash
+
+If CC_FOR_TARGET is not set when the toolchain is built (make.bash or all.bash), CC
+can be set on the command line. For example,
+
+	GOOS=ios GOARCH=amd64 CGO_ENABLED=1 CC=$(go env GOROOT)/misc/ios/clangwrap.sh go build
+
+Setting CC is not necessary if the toolchain is built with CC_FOR_TARGET set.
+
+To use the go tool to run individual programs and tests, put $GOROOT/bin into PATH to ensure
+the go_ios_$GOARCH_exec wrapper is found. For example, to run the archive/tar tests:
+
+	export PATH=$GOROOT/bin:$PATH
+	GOOS=ios GOARCH=amd64 CGO_ENABLED=1 go test archive/tar
+
+The go_ios_exec wrapper uses GOARCH to select the emulator (amd64) or the device (arm64).
+However, further setup is required to run tests or programs directly on a device.
+
+First make sure you have a valid developer certificate and have setup your device properly
+to run apps signed by your developer certificate. Then install the libimobiledevice and
+ideviceinstaller tools from https://www.libimobiledevice.org/. Use the HEAD versions from
+source; the stable versions have bugs that prevents the Go exec wrapper to install and run
+apps.
+
+Second, the Go exec wrapper must be told the developer account signing identity, the team
+id and a provisioned bundle id to use. They're specified with the environment variables
+GOIOS_DEV_ID, GOIOS_TEAM_ID and GOIOS_APP_ID. The detect.go program in this directory will
+attempt to auto-detect suitable values. Run it as
+
+	go run detect.go
+
+which will output something similar to
+
+	export GOIOS_DEV_ID="iPhone Developer: xxx@yyy.zzz (XXXXXXXX)"
+	export GOIOS_APP_ID=YYYYYYYY.some.bundle.id
+	export GOIOS_TEAM_ID=ZZZZZZZZ
+
+If you have multiple devices connected, specify the device UDID with the GOIOS_DEVICE_ID
+variable. Use `idevice_id -l` to list all available UDIDs. Then, setting GOARCH to arm64
+will select the device:
+
+	GOOS=ios GOARCH=arm64 CGO_ENABLED=1 CC_FOR_TARGET=$(pwd)/../misc/ios/clangwrap.sh ./all.bash
+
+Note that the go_darwin_$GOARCH_exec wrapper uninstalls any existing app identified by
+the bundle id before installing a new app. If the uninstalled app is the last app by
+the developer identity, the device might also remove the permission to run apps from
+that developer, and the exec wrapper will fail to install the new app. To avoid that,
+install another app with the same developer identity but with a different bundle id.
+That way, the permission to install apps is held on to while the primary app is
+uninstalled.

+## Resources for Go's trace viewer
+
+Go execution trace UI (`go tool trace`) embeds
+Chrome's trace viewer (Catapult) following the 
+[instructions](
+https://chromium.googlesource.com/catapult/+/refs/heads/master/tracing/docs/embedding-trace-viewer.md). This directory contains
+the helper files to embed Chrome's trace viewer.
+
+The current resources were generated/copied from
+[`Catapult@9508452e18f130c98499cb4c4f1e1efaedee8962`](
+https://chromium.googlesource.com/catapult/+/9508452e18f130c98499cb4c4f1e1efaedee8962).
+
+### Updating `trace_viewer_full.html`
+
+The file was generated by catapult's `vulcanize_trace_viewer` command.
+```
+$ git clone https://chromium.googlesource.com/catapult
+$ cd catapult
+$ ./tracing/bin/vulcanize_trace_viewer --config=full
+$ cp tracing/bin/trace_viewer_full.html $GOROOT/misc/trace/trace_viewer_full.html
+```
+
+We are supposed to use --config=lean (produces smaller html),
+but it is broken at the moment:
+https://github.com/catapult-project/catapult/issues/2247
+
+### Updating `webcomponents.min.js`
+
+`webcomponents.min.js` is necessary to let the trace viewer page
+to import the `trace_viewer_full.html`.
+This is copied from the catapult repo.
+
+```
+$ cp third_party/polymer/components/webcomponentsjs/webcomponents.min.js $GOROOT/misc/trace/webcomponents.min.js
+```
