3e50372f1f test: change index.go to test size of int, not GOARCH == "amd64"
Fixes the test to work correctly on other platforms with
64-bit ints, like Alpha.

761830f481 cmd/gc: fix export of inlined function body with type guard
When exporting a body containing
        x, ok := v.(Type)

the definition for Type was not being included, so when the body
was actually used, it would cause an "unknown type" compiler error.

Fixes #4370.

71282131a1 cmd/gc: fix escape analysis bug
The code assumed that the only choices were EscNone, EscScope, and EscHeap,
so that it makes sense to set EscScope only if the current setting is EscNone.
Now that we have the many variants of EscReturn, this logic is false, and it was
causing important EscScopes to be ignored in favor of EscReturn.

cb856adea9 cmd/gc: annotate local variables with unique ids for inlining
Avoids problems with local declarations shadowing other names.
We write a more explicit form than the incoming program, so there
may be additional type annotations. For example:

        int := "hello"
        j := 2

would normally turn into

        var int string = "hello"
        var j int = 2

but the int variable shadows the int type in the second line.

This CL marks all local variables with a per-function sequence number,
so that this would instead be:

        var int·1 string = "hello"
        var j·2 int = 2

Fixes #4326.

arrays and slices.

0b2353edcb cmd/5g, cmd/6g: fix out of registers with array indexing.
Compiling expressions like:
    s[s[s[s[s[s[s[s[s[s[s[s[i]]]]]]]]]]]]
make 5g and 6g run out of registers. Such expressions can arise
if a slice is used to represent a permutation and the user wants
to iterate it.

This is due to the usual problem of allocating registers before
going down the expression tree, instead of allocating them in a
postfix way.

The functions cgenr and agenr (that generate a value to a newly
allocated register instead of an existing location), are either
introduced or modified when they already existed to allocate
the new register as late as possible, and sudoaddable is disabled
for OINDEX nodes so that igen/agenr is used instead.

Update #4207.

507fcf37d2 cmd/gc: escape analysis to track flow of in to out parameters.
includes step 0: synthesize outparams, from 6600044
includes step 1,2: give outparams loopdepth 0 and verify unchanged results
         generate esc:$mask tags, but still tie to sink if a param has mask != 0
from 6610054

adds final steps:
- have esccall generate n->escretval, a list of nodes the function results flow to
- use these in esccall and ORETURN/OAS2FUNC/and f(g())
- only tie parameters to sink if tag is absent, otherwise according to mask, tie them to escretval

51e8fe5b1b cmd/gc: don't dereference a nil Type pointer in widstruct
The nil dereference in the next few lines doesn't seem

func main() {

Without this change only the following is caught:

typecheck.go:4: undefined: b

with it, we catch all the errors:

typecheck.go:3: undefined: b
typecheck.go:4: undefined: b

ebb0e5db75 test: Add rundir, rundircmpout and errorcheckdir commands to testlib and run.go
rundir will compile each file in the directory in lexicographic order, link the last file as the main package and run the resulting program. rundircmpout is an related command, that will compare the output of the program to an corresponding .out file

errorcheckdir will compile each file in a directory in lexicographic order, running errorcheck on each file as it compiles. All compilations are assumed to be successful except for the last file. However, If a -0 flag is present on the command, the last compilation will also be assumed successful

This CL also includes a small refactoring of run.go. It was getting unwieldy and the meaning of the run commands was hidden behind argument line formatting.

Today, if run.go doesn't understand a test header line it just ignores
the test, making it too easy to write or edit tests that are not actually
being run.

- expand errorcheck to accept flags, so that bounds.go and escape*.go can run.
- create a whitelist of skippable tests in run.go; skipping others is an error.
- mark all skipped tests at top of file.

Surrogate halves are part of UTF-16 and should never appear in UTF-8.

Encoding: encode as RuneError.
Decoding: convert to RuneError, consume one byte.

        runtime for range over string

6363fc5aa6 cmd/gc: fix type checking loop
CL 4313064 fixed its test case but did not address a
general enough problem:

type T1 struct { F *T2 }
type T2 T1
type T3 T2

could still end up copying the definition of T1 for T2
before T1 was done being evaluated, or T3 before T2
was done.

In order to propagate the updates correctly,
record a copy of an incomplete type for re-execution
once the type is completed. Roll back CL 4313064.

Fixes #3709.

6423682019 test/bench/go1: add go/parser benchmark
As discussed in

https://groups.google.com/d/msg/golang-dev/Na9XE6mcQyY/zbeBI7R-vnoJ

Here is a static copy of the go/parser benchmark. I ended up using
fancy encodings because the original parser.go had a number of `s
scattered throughout which made it hard to embed the source directly.

Curiously on my laptop this benchmark always scores roughly 10% higher
than the standalone benchmark. This may be down to the generation of
the fasta data set triggering the cpu governor to raise the cpu speed.
However the benchmark is consistent with itself across multiple runs.

5eb007dede runtime: work around false negative in deadlock detection
Not a complete fix for issue 3342, but fixes the trivial case.
There may still be a race in the instants before and after
a scavenger-induced garbage collection.

Intended to be "obviously safe": a call to runtime·gosched
before main.main is no different than a call to runtime.Gosched
at the beginning of main.main, and it is (or had better be)
safe to call runtime.Gosched at any point during main.

They are broken and hard to make work.

They have never worked: if you import "/tmp/x"
from "/home/rsc/p.c" then the compiler rewrites
this into import "/home/rsc/tmp/x", which is
clearly wrong.

Also we just disallowed the : character in import
paths, so import "c:/foo" is already not allowed.

Finally, in order to support absolute paths well in
a build tool we'd have to provide a mechanism to
instruct the compiler to resolve absolute imports
by looking in some other tree (where the binaries live)
and provide a mapping from absolute path to location
in that tree.  This CL avoids adding that complexity.

This is not part of the language spec (and should not be),
so no spec change is needed.

If we need to make them work later, we can.

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.

Fixes #2920.
