982322769c cmd/dist: redo flag-passing for bootstrap
This ought to revert the bad effects of
https://go-review.googlesource.com/#/c/20775/
If you don't pass BOOT_GO_GCFLAGS, you get the
old behavior.

Tweaked to allow multiple space-separated flags in
BOOT_GO_GCFLAGS.

09a9ce60c7 cmd/compile: get gcflags to bootstrap; ssa debug opts for "all"
This is intended to help debug compiler problems that pop
up in the bootstrap phase of make.bash.  GO_GCFLAGS does not
normally apply there.  Options-for-all phases is intended
to allow crude tracing (and full timing) by turning on timing
for all phases, not just one.

Phase names can also be specified using a regular expression,
for example
BOOT_GO_GCFLAGS=-d='ssa/~^.*scc$/off' \
GO_GCFLAGS='-d=ssa/~^.*scc$/off' ./make.bash

I just added this because it was the fastest way to get
me to a place where I could easily debug the compiler.

50c38d46e8 cmd/go, go/build: add support for Fortran
This change adds support for Fortran files (.f, .F, .for, .f90) to the
go tool, in a similar fashion to Objective-C/C++. Only gfortran is
supported out of the box so far but leaves other Fortran compiler
toolchains the ability to pass the correct link options via CGO_LDFLAGS.
A simple test (misc/cgo/fortran) has been added and plugged into the
general test infrastructure. This test is only enabled when the $FC
environment variable is defined (or if 'gfortran' was found in $PATH.)

Derived from CL 4114.

096b294f21 [dev.cc] cmd/go: fix expansion of 'std', add 'cmd'
The wildcard 'std' is defined in documentation to be all the packages
in the Go standard library. It has also historically matched commands
in the main repo, but as we implement core commands in Go, that
becomes problematic. We need a wildcard that means just the library,
and since 'std' is already documented to have that definition, make it so.

Add a new wildcard 'cmd' for the commands in the main repo ($GOROOT).
Commands that want both can say 'std cmd' (or 'cmd std') to get the
effect of the old 'std'.

Update make.bash etc to say both std and cmd most of the time.

Exception: in race.bash, do not install race-enabled versions of
the actual commands. This avoids trying to write binaries while
using them, but more importantly it avoids enabling the race
detector and its associated memory overhead for the already
memory-hungry compilers.

db52315c88 [dev.cc] build: do not 'clean -i std' between dist and go_bootstrap
Executing 'clean -i std' removes installed Go programs,
including the toolchain binaries we need for building.
It's not clear why the 'clean -i std' is here in the first place.
cmd/dist just removed the entire pkg tree, so everything is new.
The only reason for 'clean -i std' would be if you don't trust
that dist compiled the packages properly. If that's true for
some reason, we can fix cmd/dist, or add -a to the install
commands that follow. Perhaps clean -i std should not
remove tools, or perhaps std should not expand to any tools.
Not sure.

Also remove banner from make.bat and make.rc that was
already removed from make.bash. cmd/dist prints it now.

Also fix array size error in liblink/objfile.c.

Fixes dev.cc build.

Bootstrap the Go parts of the Go toolchain using Go 1.4,
as described in https://golang.org/s/go15bootstrap.

The first Go part of the Go toolchain will be cmd/objwriter,
but for now that's just an empty program to test that this
new code works.

Once the build dashboard is okay with this change,
we'll make objwriter a real program depended upon by the build.

20a10e7ddd build: require old Go to build new Go (and convert cmd/dist to Go)
This CL introduces the bootstrap requirement that in order to
build the current release (or development version) of Go, you
need an older Go release (1.4 or newer) already installed.
This requirement is the whole point of this CL.

To enforce the requirement, convert cmd/dist from C to Go.

With this bootstrapping out of the way, we can move on to
replacing other, larger C programs like the Go compiler,
the assemblers, and the linker.

See golang.org/s/go15bootstrap for details.

3167c12eb2 cmd/dist: support building on debian/kFreeBSD
The debian/kFreeBSD project uses the FreeBSD kernel and the debian userspace. From our point of view, this is freebsd not linux as GOOS talks about the kernel syscall interface, not the userspace (although cgo alters that). As debian/kFreeBSD is experimental at this time, I do not think it is worth the effort of duplicating all the freebsd specific code so this is proposal represents a reasonable workaround.

Currently cgo is not supported, make.bash will detect this and disable cgo automatically during the build.

In addition to these fixes, all commands now take a list of

        go fix x.go
        go vet x.go
        go test x_test.go

Preliminary tests in test.bash.
Mainly testing things that the ordinary build does not.
I don't mind if the script doesn't run on Windows.

I expect that gccgo support is now broken, and I hope that
people will feel free to file issues and/or send CLs to fix it.  :-)

7b848c6964 cmd/dist: cross-compiling fixes
This CL makes it possible to run make.bash with
GOOS and GOARCH set to something other than
the native host GOOS and GOARCH.

As part of the CL, the tool directory moves from bin/tool/
to pkg/tool/goos_goarch where goos and goarch are
the values for the host system (running the build), not
the target.  pkg/ is not technically appropriate, but C objects
are there now tool (pkg/obj/) so this puts all the generated
binaries in one place (rm -rf $GOROOT/pkg cleans everything).
Including goos_goarch in the name allows different systems
to share a single $GOROOT on a shared file system.

b3750ff52d build: rename $GOROOT/bin/go-tool to $GOROOT/bin/tool.
The go- is redundant now that the directory is required
to be inside $GOROOT.  Rob LGTMed the idea.

2050a9e478 build: remove Make.pkg, Make.tool
Consequently, remove many package Makefiles,
and shorten the few that remain.

gomake becomes 'go tool make'.

Turn off test phases of run.bash that do not work,
flagged with $BROKEN.  Future CLs will restore these,
but this seemed like a big enough CL already.

79dc34413e cmd/go: first piece of tool rearrangement
1) create go-tool dir in make.bash
2) clean up stale binaries in make.bash
3) add 'tool' command to go
4) convert goyacc->yacc as a first test tool
Since goyacc stands alone, it's a safe trial.

ed936a3f22 cmd/go: implement go get + bug fixes
Move error information into Package struct, so that
a package can be returned even if a dependency failed
to load or did not exist.  This makes it possible to run
'go fix' or 'go fmt' on packages with broken dependencies
or missing imports.  It also enables go get -fix.
The new go list -e flag lets go list process those package
errors as normal data.

Change p.Doc to be first sentence of package doc, not
entire package doc.  Makes go list -json or
go list -f '{{.ImportPath}} {{.Doc}}' much more reasonable.

The go tool now depends on http, which means also
net and crypto/tls, both of which use cgo.  Trying to
make the build scripts that build the go tool understand
and handle cgo is too much work.  Instead, we build
a stripped down version of the go tool, compiled as go_bootstrap,
that substitutes an error stub for the usual HTTP code.
The buildscript builds go_bootstrap, go_bootstrap builds
the standard packages and commands, including the full
including-HTTP-support go tool, and then go_bootstrap
gets deleted.

Also handle the case where the buildscript needs updating
during all.bash: if it fails but a go command can be found on
the current $PATH, try to regenerate it.  This gracefully
handles situations like adding a new file to a package
used by the go tool.
