38e7fddc21 Show BUG comments in godoc: 
ast.go:
- rename Comments -> CommentGroup (less confusion)
- change all comments/docs to be *CommentGroup

filter.go:
- do not remove unassociated comments from program as part
  of export filtering (they are needed by doc.go for BUG comments)

scanner.go:
- exclude '\n' from //-style comments

parser.go:
- rewrote collection of comments: now all collected comments
  are *ast.CommentGroups
- clarified distinction between leading and trailing comments
- fixed a bug in comment collection (parseGenDecl);
  corresponding test case is in printer/testdata
- extra documentation

doc.go:
- collect BUG comments
- corresponding fix for parser bug in comment collection

comment.go:
- simplified regex

printer.go:
- adjust comment printing to new representation

printer_test.go, testdata/*:
- enable printing of doc comments
- extended tests

package.html, package.txt:
- added Bugs section

gofmt:
- enable printing of doc comments

903d28bd1e ANY is already checked separately, 
so remove code from go.y.

show original types in badtype; don't remove pointers.
not sure why this was here but it confuses things
if the bad part involves two named pointer types
with different names but the same pointed-at type.

88e7fd5410 in preparation for changing 6g's behavior to 
align the output args separately from the input args,
change cgo2c to insert the necessary padding
when the two arg lists are concatenated in the c
translation.

for example, there is a runtime

	func indexstring(s string, i int32) (b byte)

right now in 6g those arguments are aligned in one
struct with s at offset 0, i at 16, and b at 20.
soon the b byte will be in its own struct and structs
are 8 aligned, so it will be b at 24.

right now cgo2c generates:

	void indexstring(string s, int32 i, byte b)

this CL makes it generate, in --6g mode:

	void indexstring(string s, int32 i, uint32, byte b)

this is valid 6c input, although not valid gcc input.
(the code is being generated for 6c only anyway.)

also, allow C code to be mixed in among the Go funcs.
every instance of the token `func' is expected to start
a new go func.

in a cell makes a final cell in that line
   (this showed up as occasionally missing single spaces in
   godoc-formatted declarations that fit on a single line)

2) Cleaned up tabwriter implementation a bit:
   - replaced local unicodeLen() with utf8.RuneCount()
   - instead of having 2 parallel arrays for line widths and sizes,
     have a single array of cells containing a width and size
   - factored code a bit better
   - added more comments
   - added testnames to tabwriter tests
   - added more test cases and fixed a broken test case that
     now works correctly

a00bfb5b49 8g: 
* floating point -> integer conversions.
    x86 defines that overflow/underflow
    results in 1<<15, 1<<31, 1<<63 for
    int16, int32, int64.  when building the
    unsigned conversions out of the native signed
    ones, 8g turns overflow/underflow into zero.
    the spec does not say what should happen.

  * many tiny bug fixes.  can run a large number
    of files from go/test now, and can fmt.Printf.

  * struggling with byte register allocation
    and float32 computation.

aa3222d88f 32-bit fixes in lessstack. 
avoid tight coupling between deferreturn and jmpdefer.
before, jmpdefer knew the exact frame size of deferreturn
in order to pop it off the stack.  now, deferreturn passes
jmpdefer a pointer to the frame above it explicitly.
that avoids a magic constant and should be less fragile.

602a446b74 new syscall package: manually maintained files and scripts. 
auto-generated files and deletions are in another CL.

goals for new syscall:
	* automate as much as possible
	* do not let clients do unsafe things
	* use simple types (int not int64)
	* fewer files

the files are renamed from foo_amd64_linux to foo_linux_amd64,
both because it reads better (all the linux are related, all the amd64 less so)
and because it made it easier to replace the existing ones.

e81d97ea84 clean up gmove: 
* conversions all in one place.
	* no separate load, store phases;
	  direct memory addressing when possible
	  (this is the x86 after all!).
	  avoids extra registers, extra MOVQs.
	* fixes int32 -> uint64 bug
	  (was zero-extending)

2d5d4a1b41 reflect bug: NewZeroValue was refusing to create slices. 
as far as I can tell there's no reason not to.

the Nillable test was succeeding because NewZeroValue
returned the nil interface value and the type guard
was letting it through.  the only change in the test is
more detail in the print.

2da5022bcf change representation of interface values. 
this is not a user-visible change.

before, all interface values were

	struct Itype {
		Sigt *type;
		Sigi *inter;
		void *method[n];
	}

	struct Iface {
		void *addr;
		Itype *itype;
	}

the itype is basically a vtable, but it's unnecessary
if the static type is interface{ }.
for interface values with static type empty, the
new representation is

	struct Eface {
		void *addr;
		Sigt *type;
	}

this complicates the code somewhat, but
it reduces the number of Itypes that
have to be computed and cached,
it opens up opportunities to avoid function
calls in a few common cases,
and it will make it possible to lay out
interface{} values at compile time,
which i think i'll need for the new reflection.
