6bcfb95168 8a: fixes for Plan 9 build 
8a/a.h:
. Removed <u.h> and <libc.h> includes as they work better in "a.y".
. Made definition of EOF conditional as it's defined in the Plan 9
  header files, but not elsewhere.

8a/a.y:
. Added <u.h> and <libc.h> because <stdio.h> in Plan 9 needs them.
  Sequence <u.h>, <stdio.h>, <libc.h> recommended by RSC.

8a/lex.c:
. Added <u.h> and <libc.h> as now needed by "a.h".
. Dropped <ctype.h>.

cc/lexbody:
. exit() -> exits().
. Dropped unwanted incrementation.

cc/macbody:
. Adjusted a few format specifications.

9843ca5e2b gotest: add -test.benchtime and -test.cpu flags. 
-test.benchtime allows to specify benchmark execution time.
-test.cpu allows to execute tests/benchmarks for several
values of GOMAXPROCS.

c475c3071a 5c: do not use R9 and R10 
This program used to use R9 and R10.
Now it fails to compile (out of registers).
I used to know a simpler test but can't remember it.

Learned something new: Rietveld refuses change
list descriptions bigger than 10 kB.

89d334ffe1 ld: don't attempt to build dynamic sections unnecessarily 
This prevents ld from generating zeroed symtab entries for
sections that aren't going to be generated because dynamic
linkage has been disabled (-d was used or no dynamic libs
were seen).  Even though they were not explicitly added by
doelf, the section creation process was making them
reachable again.

The windows head is being disconsidered for this because
apparently it's not taking into account debug['d'].

This makes elflint 0.1% happier.

712fb6dcd3 os.Error API: don't export os.ErrorString, use os.NewError consistently 
This is a core API change.

1) gofix misc src
2) Manual adjustments to the following files under src/pkg:
   gob/decode.go
   rpc/client.go
   os/error.go
   io/io.go
   bufio/bufio.go
   http/request.go
   websocket/client.go
as well as:
   src/cmd/gofix/testdata/*.go.in (reverted)
   test/fixedbugs/bug243.go
3) Implemented gofix patch (oserrorstring.go) and test case (oserrorstring_test.go)

Compiles and runs all tests.

10b5519d3a 8l: more fixes for Plan 9 
Once these changes are effected, it is possible to construct
"8l" native on a (386?) Plan 9 system, albeit with assistance
from modules such as mkfiles that are not (yet) included in any
public patches.

8l/asm.c:
. Corrected some format qualifiers.

8l/list.c:
. Cast a print() argument to (int) to match the given format.
  It may be possible to change the format (%R), but I have not
  looked into it.

8l/obj.c:
. Removed some unused code.

8l/span.c:
. Removed unnecessary incrementation on "bp".
. Corrected some format qualifiers.

ld/data.c:
. Corrected some format qualifiers.
. Cast print argument to (int): used as field size.
. Use braces to suppress warning about empty if() statements.

ld/dwarf.c:
. Trivial spelling mistake in comment.

ld/ldelf.c:
. Added USED() statements to silence warnings.
. Dropped redundant address (&) operators.
. corrected some format qualifiers.
. Cast to (int) for switch selection variable.

ld/macho.c:
. Added USED() statements to silence warnings.

ld/ldpe.c:
. Added USED() statements to silence warnings.
. More careful use of "sect" variable.
. Corrected some format qualifiers.
. Removed redundant assignments.
. Minor fix dropped as it was submitted separately.

ld/pe.c:
. Dropped <time.h> which is now in <u.h>.
. Dropped redundant address (&) operators.
. Added a missing variable initialisation.

ld/symtab.c:
. Added USED() statements to silence warnings.
. Removed redundant incrementation.
. Corrected some format qualifiers.

All the above have been tested against a (very) recent release
and do not seem to trigger any regressions.

All review suggestions have been incorporated.

c319fb07bc goinstall: Add support for arbitary code repositories 
Extend goinstall to support downloading from any hg/git/svn/bzr hosting
site, not just the standard ones.  The type of hosting is automatically
checked by trying all the tools, so the import statement looks like:

  import "example.com/mything"

Which will work for Mercurial (http), Subversion (http, svn), Git (http,
git) and Bazaar (http, bzr) hosting.

All the existing package imports will work through this new mechanism,
but the existing hard-coded host support is left in place to ensure
there is no change in behaviour.

Referer, UserAgent, and cookies which caused confusion and
bugs.  It also didn't allow us to expand the package over
time, since the way to access fields would be in the Headers
one day and promoted to a field the next day.  That would be
hard to gofix, especially with code ranging over Headers.

After a discussion on the mail package's design with a similar
problem, we've designed to make the Headers be the source of
truth and add accessors instead.

Request:
change: Referer -> Referer()
change: UserAgent -> UserAgent()
change: Cookie -> Cookies()
new: Cookie(name) *Cookie
new: AddCookie(*Cookie)

Response:
change: Cookie -> Cookies()

Cookie:
new: String() string

340251e43d build: fix header files for Plan 9 
The "elf.h" header changes involve only comments, the released
Plan 9 C preprocessing function does not cope with multiline
comments following the #define keyword.  All multiline comments
have been moved to the line above the associated definition.
Sigh!  Fixing the Plan 9 compiler is not an option.

<time.h> does not exist in the Plan 9 Native library.  I have
moved it from src/cmd/ld/pe.h to include/u.h. RSC correctly points
out that this copy of <u.h> is not the one used to compile the
Go release on Plan 9 platforms.

first entry and requires all fields inside to be set
to zero.

The list of changes is as follows:

  · reserve the first symbol entry (as noted above)
  · fix the section indices for .data and .bss symbols
  · factor out common code for Elf32 and Elf64
  · remove the special case for elfsymo in [568]l/asm.c:/^asmb
  · add the "etext" symbol in 6l
  · add static symbols

0025 (x.go:5) CALL    ,runtime.printnl+0(SB)
0026 (x.go:6) RET     ,

is problematic because the liveness range for
autotmp_0000 (0006-0009) is nested completely
inside a span where BX holds a live value (0003-0015).
Because the register allocator only looks at 0006-0009
to see which registers are used, it misses the fact that
BX is unavailable and uses it anyway.

The n->pun = anyregalloc() check in tempname is
a workaround for this bug, but I hit it again because
I did the tempname call before allocating BX, even
though I then used the temporary after storing in BX.
This should fix the real bug, and then we can remove
the workaround in tempname.

The code creates pseudo-variables for each register
and includes that information in the liveness propagation.
Then the regu fields can be populated using that more
complete information.  With that approach, BX is marked
as in use on every line in the whole span 0003-0015,
so that the decision about autotmp_0000
(using only 0006-0009) still has all the information
it needs.

This is not specific to the 386, but it only happens in
generated code of the form

        load R1
        ...
        load var into R2
        ...
        store R2 back into var
        ...
        use R1

and for the most part the other compilers generate
the loads for a given compiled line before any of
the stores.  Even so, this may not be the case everywhere,
so the change is worth making in all three.

These changes are not particularly invasive and have been tested
as broadly as possible.

8l/l.h:
  -	#pragma varargck: added some, removed duplicates.

ld/dwarf.c:
  -	As Plan 9 has no NULL, changed all occurrences to nil.
  -	Added USED(size); where necessary.
  -	Added (void) argument in definition of finddebugruntimepath().
  -	Plan 9 compiler was complaining about multiple
        assignments, repeaired by breaking up the commands.
  -	Correction: havedynamic = 1; restored.

ld/go.c:
  -	Needed USED(file); in two functions.
  -	Removed unused assignments flagged by the Plan 9 compiler.

ld/lib.c:
  -	Replaced unlink() with remove() which seems available everywhere.
  -	Removed USED(c4); and USED(magic) no longer required.
  -	Removed code flagged as unused by the Plan 9 compiler.
  -	Added attributes to a number of format strings.

Start (and Run) deal with copying stdout, stdin,

a825e8a69f cgo: restrict #cgo directives to prevent shell expansion 
Fixes issue #1879.

Directives were not directly expanded, but since their
content ended up in makefiles, further expansion would
take place there.  This prevents such artifacts by
restricting the set of characters that may be used in
a directive value.

To build the list of safe characters I went through the
contents of /usr/lib/pkgconfig and extracted LDFLAGS
and CFLAGS information, so hopefully this is a
reasonable default to get started.

is to simulate an ARMv3 and just let the unaligned accesses
stop at the word boundary, resulting in all kinds of surprises.

Fixes #1240.

507df959e4 runtime: drop chan circular linked list in favor of circular buffer 
The list elements are already being allocated out of a
single memory buffer.  We can drop the Link* pointer
following and the memory it requires, replacing it with
index operations.

The change also keeps a channel from containing a pointer
back into its own allocation block, which would create a
cycle.  Blocks involved in cycles are not guaranteed to be
finalized properly, and channels depend on finalizers to
free OS-level locks on some systems.  The self-reference
was keeping channels from being garbage collected.

runtime-gdb.py will need to be updated in order to dump
the content of buffered channels with the new data structure.

Fixes #1676.

7d77e3117c gotest: another try at flags. 
doc.go contains the details. The short story:
- command line is passed to the binary
- a new flag, -file, is needed to name files
- known flags have the "test." prefix added for convenience.
- gotest-specific flags are trimmed from the command line.

The effect should be that most existing uses are unaffected,
the ability to name files is still present, and it's nicer to use.
The downside is a lot more code in gotest.

Also allow a test to be called just Test.

1afc37fa7e go/printer/gofmt: remove special case for multi-line raw strings 
As a special case, multi-line raw strings (i.e., strings in `` quotes)
were not indented if they were the only token on a line. This heuristic
was meant to improve formatting for multi-line raw strings where sub-
sequent lines are not indented at the level of the surrounding code.
Multiple people have complained about this. Removing the heuristic
again because it makes the formatting more regular, easier to under-
stand, and simplifies the implementation.

- manual changes to ebnf/ebnf_test.go for readability
- gofmt -w src misc

5be77a204b go/ast: implemented NewPackage 
NewPackage creates an ast.Package node from
a set of package files and resolves unresolved
identifiers.

Also:
- Changed semantics of Scope.Insert: If an
  object is inserted w/o errors, the result
  is nil (before it was obj).
- Fixed an identifier resolution bug in the
  parser: map keys must not be resolved.

gotype runs through several go/* packages
and successfully resolves all (non-field/method)
identifiers.

d406f8f650 testing: set up structure for faster testing using the new -test.short flag. 
New make target "testshort" runs "gotest -test.short" and is invoked
by run.bash, which is invoked by all.bash.

Use -test.short to make one package (crypto ecdsa) run much faster.
More changes to come.

Once this is in, I will update the long-running tests to use the new flag.

Use memoization to avoid repeated recomputation of nested
node sizes. Speeds up testdata/slow.input by several orders
of magnitude.
