The Go programming language

Fixes #8348. Trying to work around clang's dodgy support for .arch by reverting to the external assembler didn't work out so well. Minux had a much better solution to encode the instructions we need as .word directives which avoids .arch altogether. I've confirmed with gdb that this form produces the expected machine code Dump of assembler code for function crosscall_arm1: 0x00000000 <+0>: push {r4, r5, r6, r7, r8, r9, r10, r11, r12, lr} 0x00000004 <+4>: mov r4, r0 0x00000008 <+8>: mov r5, r1 0x0000000c <+12>: mov r0, r2 0x00000010 <+16>: blx r5 0x00000014 <+20>: blx r4 0x00000018 <+24>: pop {r4, r5, r6, r7, r8, r9, r10, r11, r12, pc} There is another compilation failure that blocks building Go with clang on arm # ../misc/cgo/test # _/home/dfc/go/misc/cgo/test /tmp/--407b12.s: Assembler messages: /tmp/--407b12.s:59: Error: selected processor does not support ARM mode `blx r0' clang: error: assembler command failed with exit code 1 (use -v to see invocation) FAIL _/home/dfc/go/misc/cgo/test [build failed] I'll open a new issue for that LGTM=iant R=iant, minux CC=golang-codereviews https://golang.org/cl/158180047 |

Binary Distribution Notes
If you have just untarred a binary Go distribution, you need to set
the environment variable $GOROOT to the full path of the go
directory (the one containing this README). You can omit the
variable if you unpack it into /usr/local/go, or if you rebuild
from sources by running all.bash (see doc/install.html).
You should also add the Go binary directory $GOROOT/bin
to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might
put the following in your .profile:
export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin
See doc/install.html for more details.
