Russ Cox 1d66144bfd build: update comments about Go 1.4 in make.bash, make.bat, make.rc
A few lingering references to Go 1.4 remain.
Fix them, and document the ones that should stay.

For #44505.
Fixes #54301.

Russ Cox 3315066f46 cmd/link: detect glibc vs musl ldso at link time
Doing the test at link time lets us distribute one Linux toolchain
that works on both glibc-based and musl-based Linux systems.
The old way built a toolchain that only ran on one or the other.

Fixes #54197.

Bryan C. Mills 69756b38f2 cmd/dist: move more environment logic into cmd/dist from make and run scripts
'go tool dist env' outputs different (and fewer) environment variables
than 'go env'. The 'go tool dist env' variables should be
authoritative, whereas many printed by 'go env' are merely
informational (and not intended to be overridden in the actual
environment).

Fixes #52009

Russ Cox ef55053354 make.bash: disable GOEXPERIMENT when using bootstrap toolchain
When using Go 1.4 this doesn't matter, but when using Go 1.17,
the bootstrap toolchain will complain about unknown GOEXPERIMENT settings.
Clearly GOEXPERIMENT is for the toolchain being built, not the bootstrap.

Already submitted as CL 395879 on the dev.boringcrypto branch,
but needed on master to set up GOEXPERIMENT=boringcrypto
builder ahead of merge.

For #51940.

Dilyn Corner 9f2a71b6e7 make.bash: this change modifies Go to correctly select a dyamic linker
Alpine Linux is not the only musl-based Linux distribution. Checking for
/etc/alpine-release excludes many other distributions (Oasis, KISS,
Sabotage, sta.li). Not having the correct GO_LDSO set during go builds will
result in the wrong linker/loader on nonalpine musl systems for pie builds.
Instead, the dynamic loader should be checked for every system and set. This
results in the correct dynamic linker being found on glibc systems
(/lib/ld-linux-x86-64.so.2) and musl systems (/lib/ld-musl-x84_64.so.1).

Austin Clements eda1d40544 make.bash: avoid warning when bootstrap doesn't support GOOS/GOARCH
Currently, if make.bash is run with a GOOS or GOARCH that the
bootstrap toolchain doesn't support, it will print an ominous but
harmless warning like:

  2020/09/21 09:05:27 unsupported GOARCH arm64

This comes from the invocation of "go version" to get the exact
bootstrap toolchain version.

Since the GOOS and GOARCH don't matter for this purpose, this CL
simply clears them on the invocation of the bootstrap toolchain's "go
version".

Fixes #41525.

Russ Cox c1a4fc3b36 cmd/go: add $GOFLAGS environment variable
People sometimes want to turn on a particular go command flag by default.
In Go 1.11 we have at least two different cases where users may need this.

1. Linking can be noticeably slower on underpowered systems
due to DWARF, and users may want to set -ldflags=-w by default.

2. For modules, some users or CI systems will want vendoring always,
so they want -getmode=vendor (soon to be -mod=vendor) by default.

This CL generalizes the problem to “set default flags for the go command.”

$GOFLAGS can be a space-separated list of flag settings, but each
space-separated entry in the list must be a standalone flag.
That is, you must do 'GOFLAGS=-ldflags=-w' not 'GOFLAGS=-ldflags -w'.
The latter would mean to pass -w to go commands that understand it
(if any do; if not, it's an error to mention it).

For #26074.
For #26318.
Fixes #26585.

POSIX Shell only supports = to compare variables inside '[' tests. But
this is Bash, where == is an alias for =. In practice they're the same,
but the current form is inconsisnent and breaks POSIX for no good
reason.

Ian Lance Taylor 135ce43c87 cmd/go: when expanding "cmd", skip vendored main packages
We are vendoring pprof from github.com/google/pprof, which comes with
a main package. If we don't explicitly skip that main package, then
`go install cmd` will install the compiled program in $GOROOT/bin.

Fixes #19441.

David Chase 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.

kortschak 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.

Russ Cox 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.

Russ Cox 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.

Russ Cox 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.
