1d6eb2e9fa cmd/gc: fix handling of struct padding in hash/eq.
The test case of issue 4585 was not passing due to
miscalculation of memequal args, and the previous fix
does not handle padding at the end of a struct.

Handling of padding at end of structs also fixes the case

8fff2525cb cmd/gc: add space to export data to match linker expectations
The linker split PKGDEF into (prefix, name, def) pairs,
and defines def to begin after a space following the identifier.
This is totally wrong for the following export data:

        func "".FunctionName()
        var SomethingCompletelyUnrelated int

The linker would parse
    name=`"".FunctionName()\n\tvar`
    def=`SomethingCompletelyUnrelated int`
since there is no space after FunctionName.

9aef20e823 cmd/gc: fix wrong interaction between inlining and embedded builtins.
The patch makes the compile user an ordinary package-local
symbol for the name of embedded fields of builtin type.

This is incompatible with the fix delivered for issue 2687
(revision 3c060add43fb) but fixes it in a different way, because
the explicit symbol on the field makes the typechecker able to
find it in lookdot.

54e8d504e8 cmd/5g: use MOVB for fixed array nil check
Fixes #4396.

For fixed arrays larger than the unmapped page, agenr would general a nil check by loading the first word of the array. However there is no requirement for the first element of a byte array to be word aligned, so this check causes a trap on ARMv5 hardware (ARMv6 since relaxed that restriction, but it probably still comes at a cost).

Switching the check to MOVB ensures alignment is not an issue. This check is only invoked in a few places in the code where large fixed arrays are embedded into structs, compress/lzw is the biggest offender, and switching to MOVB has no observable performance penalty.

Thanks to Rémy and Daniel Morsing for helping me debug this on IRC last night.

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

cd22afa07b test: expand run.go's errorcheck, make clear which bugs run
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.

was done.

record a copy of an incomplete type for re-execution
once the type is completed. Roll back CL 4313064.

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.

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.

fff732ea2c 6g,8g: make constant propagation inlining-friendly.
This changes makes constant propagation compare 'from' values using node
pointers rather than symbol names when checking to see whether a set
operation is redundant. When a function is inlined multiple times in a
calling function its arguments will share symbol names even though the values
are different. Prior to this fix the bug409 test would hit a case with 6g
where an LEAQ instruction was incorrectly eliminated from the second inlined
function call. 8g appears to have had the same bug, but the test did not fail
there.

ee9bfb023a gc: fix order of evaluation
Pulling function calls out to happen before the
expression being evaluated was causing illegal
reorderings even without inlining; with inlining
it got worse.  This CL adds a separate ordering pass
to move things with a fixed order out of expressions
and into the statement sequence, where they will
not be reordered by walk.

Replaces lvd's CL 5534079.

Fixes #2740.

387e7c2742 test: explicitly use variables to avoid gccgo "not used" error
I haven't looked at the source, but the gc compiler appears to
omit "not used" errors when there is an error in the
initializer.  This is harder to do in gccgo, and frankly I
think the "not used" error is still useful even if the
initializer has a problem.  This CL tweaks some tests to avoid
the error, which is not the point of these tests in any case.

290e68b983 gc: undo most of 'fix infinite recursion for embedded interfaces'
Preserve test.

changeset:   11593:f1deaf35e1d1

summary:     gc: fix infinite recursion for embedded interfaces

This is causing 'interface type loop' errors during compilation
of a complex program.  I don't understand what's happening
well enough to boil it down to a simple test case, but undoing
this change fixes the problem.

The change being undone is fixing a corner case (uses of
pointer to interface in an interface definition) that basically
only comes up in erroneous Go programs.  Let's not try to
fix this again until after Go 1.

Unfixes issue 1909.

c50e4f5e2f testing: allow benchmarks to print and fail
Refactors the benchmarks and test code.
Now benchmarks can call Errorf, Fail, etc.,
and the runner will act accordingly.

Because functionality has been folded into an
embedded type, a number of methods' docs
no longer appear in godoc output. A fix is
underway; if it doesn't happen fast enough,
I'll add wrapper methods to restore the
documentation.
