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.

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.

This change records more metadata about what
influenced the creation of the object file.
Specifically, if a package imports, say, "fmt" but does not
need to describe any fmt types in its own export data,
that package's object file did not mention the dependency
on "fmt" before. Now it does.
Listing the import is purely informational.
It has no effect on which files are opened or consulted
when importing a package.
Import lines are marked indirect when they are needed
to explain the API but were not imported directly.
For example http imports crypto/tls and exports
a struct with a field of type tls.ConnectionState,
which contains an x509.Certificate. Since http does
not import x509 but needs to explain the x509.Certificate
type in its export data, the import of x509 is marked
as indirect. These import lines were always present;
marking them with the indirect comment makes clear
which were imported directly and which are incidental.

Much of the bulk of Go binaries is the symbol tables,
which give a name to every C string, Go string,
and reflection type symbol. These names are not worth
much other than seeing what's where in a binary.
This CL deletes all those names from the symbol table,
instead aggregating the symbols into contiguous blocks
and giving them the names "string.*", "go.string.*", and "type.*".
Before:
$ 6nm $(which godoc.old) | sort | grep ' string\.' | tail -10
59eda4 D string."aa87ca22be8b05378eb1c71...
59ee08 D string."b3312fa7e23ee7e4988e056...

59f060 D string."method(S *scanner.Scann...
59f12c D string."func(*struct { begin in...
59f194 D string."method(ka *tls.ecdheRSA...
$
After:
$ 6nm $(which godoc) | sort | grep ' string\.' | tail -10
5e6a30 D string.*
$
Those names in the "Before" are truncated for the CL.
In the real binary they are the complete string, up to
a certain length, or else a unique identifier.
The same applies to the type and go.string symbols.
Removing the names cuts godoc by more than half:
-rwxr-xr-x 1 rsc rsc 9153405 2011-03-07 23:19 godoc.old
-rwxr-xr-x 1 rsc rsc 4290071 2011-03-07 23:19 godoc

The recursive algorithm used to parse types in cgo
has a bug related to building the C type representation.
As an example, when the recursion starts at a type *T,
the C type representation won't be known until type T
itself is parsed. But then, it is possible that type T
references the type **T internally. The latter
representation is built based on the one of *T, which
started the recursion, so it won't attempt to parse it
again, and will instead use the current representation
value for *T, which is still empty at this point.
This problem was fixed by introducing a simple TypeRepr
type which builds the string representation lazily,
analogous to how the Go type information is built within
the same algorithm. This way, even if a type
representation is still unknown at some level in the
recursion, representations dependant on it can still
be created correctly.

Neither gofmt nor godoc are making use of a Styler (for
token-specific formatting) anymore. Stylers interacted in complicated
ways with HTML-escaping which was why the printer needed an HTML mode
in the first place.
godoc now uses a more powerful and general text formatting
function that does HTML escaping, text selection, and can
handle token-specific formatting if so desired (currently
used only for comments).
As a consequence, cleaned up uses of go/printer in godoc;
simplified the various write utility functions, and also
removed the need for the "html" template format (in favor of
html-esc which now does the same and is used more pervasively).
Applied gofmt -w src misc to verify no changes occured,
and tested godoc manually.
There should be no visible changes except that (type) code
snippets presented for godoc package documentation now
uses the same formatting as for general source code and
thus comments get the comment-specific color here as well
(not the case at the moment).

Structs defined in C as containing a field with
an enum type are currently translated to Go as
a struct with an unsigned integer field, even if
some of the values contained in the enum are
negative.
This modification takes in consideration the values
defined in the enum, and conditionally defines the
Go type as signed if necessary.
The logic introduced was tested with gcc, which
will increase the type size if it contains both
negative numbers and values greater than 2^b/2-1,
and refuses to compile values which would be
problematic (2^64-1, but in fact the ISO C
restricts the range to the size of int).

The object files begin with a header that is
$GOARCH
on a line by itself. This CL changes that header to
go object $GOOS $GOARCH release.2011-01-01 4567+
where the final two fields are the most recent release
tag and the current hg version number.
All objects imported into a Go compilation or linked into an
executable must have the same header line, and that header
line must match the compiler and linker versions.
The effect of this will be that if you update and run all.bash
and then try to link in objects compiled with an earlier version
of the compiler (or invoke the wrong version of the compiler),
you will get an error showing the different headers instead
of perhaps silent incompatibility.
Normal usage with all.bash should be unaffected, because
all.bash deletes all the object files in $GOROOT/pkg/$GOOS_$GOARCH
and cleans all intermediate object files before starting.
This change is intended to diagnose stale objects arising when
users maintaining alternate installation directories forget to
rebuild some of their files after updating.

#pragma dynexport is no longer needed for
this use of cgo, since the gcc and gc code are
now linked together into the same binary.
It may still be necessary later.
On the Mac, you cannot use the GOT to resolve
symbols that exist in the current binary, so 6l and 8l
translate the GOT-loading mov instructions into lea
instructions.
On ELF systems, we could use the GOT for those
symbols, but for consistency 6l and 8l apply the
same translation.
The translation is sketchy in the extreme
(depending on the relocation being in a mov
instruction) but it verifies that the instruction
is a mov before rewriting it to lea.
Also makes typedefs global across files.

To enable use -fulltext flag; e.g.: godoc -v -fulltext -http=:7777
Enabling the fulltext index will use significantly more memory as
the text of all source code, the respective suffixarray, and the
file set data structure is kept in memory. At the moment there is
about 6Mb of source code (~1400 files) indexed under GOROOT.
Source code + suffix array together consume 5*(size of source) or
about 30Mb. The file set data structure consumes about 4b/src line.
By default only up to 5000 results are shown for now.
The presentation of the results needs tuning. In particular,
if a string is found, clicking on the respective file does not
highlight them, yet.
At the moment, only Go source files are indexed. Eventually,
the full text index should encompass other files as well.

- change Walk signature to use an ast.Node instead of interface{}
- add Pos functions to a couple of ast types to make them proper nodes
- explicit nil checks where a node can be nil; incorrect ASTs cause Walk to crash
For now ast.Walk is exercised extensively as part of godoc's indexer;
so we have some confidence in its correctness. But this needs a test,
eventually.
Fixes#1326.

Specifically:
* lib/godoc:
- provide file set (FSet) argument to formatters where needed
* src/cmd:
- cgo, ebnflint, godoc, gofmt, goinstall: provide file set (fset) where needed
- godoc: remove local binary search with sort.Search (change by rsc),
extract file set for formatters
* src/pkg:
- exp/eval: remove embedded token.Position fields from nodes and replace
with named token.Pos fields; add corresponding Pos() accessor methods
- go/token: added file.Line(), changed signature of File.Position()
* test/fixedbugs/:
- bug206.go: change test to not rely on token.Pos details
* added various extra comments
* Runs all.bash
* gofmt formats all of src, misc w/o changes
* godoc runs
* performance:
- The new version of godoc consumes about the same space after indexing
has completed, but indexing is half the speed. Significant space savings
are expected from smaller ASTs, but since they are thrown away after a
file has been indexed, this is not visible anymore. The slower indexing
time is due to the much more expensive computation of line information.
However, with the new compressed position information, indexing can be
rewritten and simplified. Furthermore, computing the line info can be
done more efficiently.
New godoc, immediately after indexing completed (best of three runs):
PID COMMAND %CPU TIME #TH #PRTS #MREGS RPRVT RSHRD RSIZE VSIZE
44381 godoc 0.0% 0:38.00 4 19 149 145M 184K 148M 176M
2010/12/03 17:58:35 index updated (39.231s, 18505 unique words, 386387 spots)
2010/12/03 17:58:35 bytes=90858456 footprint=199182584

Old godoc, immediately after indexing completed (best of three runs):
PID COMMAND %CPU TIME #TH #PRTS #MREGS RPRVT RSHRD RSIZE VSIZE
23167 godoc 0.0% 0:22.02 4 17 132 129M 184K 132M 173M
2010/12/03 14:51:32 index updated (24.892s, 18765 unique words, 393830 spots)
2010/12/03 14:51:32 bytes=66404528 footprint=163907832
2010/12/03 14:51:32 bytes=46282224 footprint=163907832
The different numbers for unique words/spots stem from the fact the the
two workspaces are not exactly identical. The new godoc maintains a large
file set data structure during indexing which (probably) is the reason
for the larger heap (90858456 vs 66404528) before garbage collection.

8l was broken by commit 7ac0d2eed9, it caused .data to be page aligned in the file - which is not how Plan 9 expects things to be.
Also .rodata was layed out in a similar fashion.
Not sure when signame was introduced, but added a stub.
Removed the symo assignment in asm.c as it is not currently used.
Fix runtime breakage after commit 629c065d36 which prefixes all external symbols with runtime·.
