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.

99686ec789 cgo: fix dwarf type parsing
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.

1169559658 cgo: use correct frame size for 0 arguments
Passing a frame size of 1 was causing the cgo callback
to push 1 byte of arguments onto the stack, making
the stack pointer misaligned, which had the effect of
hiding all the pointers on the stack from the garbage
collector.

SWIG only wraps calls to C++ virtual methods, so it
always has at least 1 argument, so SWIG does not need
to be fixed too.

Fixes #1328.

4521782514 cgo: fix handling of signed enumerations
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).

0cd3475386 misc/cgo/life: fix, add to build
#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.

Fixes #1345.

5a9ad8b9e3 go/ast: use token.Pos instead of token.Position; adjust all dependent code
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
	2010/12/03 17:58:36 bytes=47858568 footprint=167295224

	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.

	_cgo_free
	_cgo_malloc
	libcgo_thread_start
	initcgo
	ncgocall

	** known to linker **

Tested on darwin/386, darwin/amd64, linux/386, linux/amd64.

Built (but not tested) for freebsd/386, freebsd/amd64, linux/arm, windows/386.

1f9dfa294f go AST: First step towards augmenting AST with full type information.
- change ast.Ident back to contain the name and adjust all dependent code
- identifier object information will be added again through an optional
  typechecker phase (in the works).
- remove tracking of scopes in parser - it's easier to do this in a separate
  phase (in the works)
- in godoc, generate popup info table directly instead of through a formatter
  for simpler data flow (at the expense of a little bit more code)

Runs all tests.

As a result of this change, the currently shown popup information
(const, var, type, func, followed by identifier name) will not be
shown anymore temporarily.

1192c175fe Correct _cgo_free when C ABI does not pass first arg on stack.
It turns out that _cgo_malloc is used, via cmalloc in
runtime/cgocall.c, which is called by code generated by out.go
for the ·_C_CString function.  I can't find a call to
_cgo_free, but given _cgo_malloc we might as well keep
_cgo_free.  This patch fixes it so that it should work on

12e7ce95c6 Add //export to cgo.
The new //export comment marks a Go function as callable from
C.  The syntax is "//export NAME" where NAME is the name of
the function as seen from C.  If such a comment is seen, cgo
will generate two new files: _cgo_export.h and _cgo_export.c.
The _cgo_export.h file provides declarations which C code may
use to call Go functions.  The _cgo_export.c file contains
wrappers, and is to be compiled with gcc.

The changes to Make.pkg support using this from a Go Makefile,
though it could probably be more convenient.

72ec930fa7 Fix cgo for GCC 4.4
Firstly, with -Werror, GCC switched to printing warnings starting
with "error:". Widening the string matches solves this as the messages
are otherwise unchanged.

Secondly, GCC 4.4 outputs DWARF sections with with NUL bytes in all
the offsets and requires the relocation section for .debug_info to be
processed in order to result in valid DWARF data. Thus we add minimal
handling for relocation sections, which is sufficient for our needs.
