This is a just a file move with no other changes
besides the manual import path adjustments in these
two files:
src/pkg/exp/gotype/gotype.go
src/pkg/exp/gotype/gotype_test.go
Note: The go/types API continues to be subject to
possibly significant changes until Go 1.1. Do not
rely on it being stable at this point.

composite literal keys that are identifiers;
it needs type information.
Instead, try to resolve them but leave final

The new garbage collector (CL 6114046) may find the fake *[]byte value
and interpret its contents as bytes rather than as potential pointers.
This may lead the garbage collector to free memory blocks that
shouldn't be freed.

Proper local system log semantics still need to be
created for Plan 9. In the meantime, the test suite
(viz., exp/gotype) expects there to be some Go
source for each import path. Thus, here is a stub,
equivalent to syslog_windows, for this purpose.

- added Context type for configuration of type checker
- type check all function and method bodies
- (partial) fixes to shift hinting (still not complete)
- revamped test harness - does not rely on specific position
representation anymore, just a standard (compiler) error
message
- lots of bug fixes

Motivations:
- Simpler UI. Previous API proved a bit awkward for practical purposes.
- Iter is often used in cases where one want to be able to bail out early.
The old implementaton had too much look-ahead to be efficient.
Disadvantages:
- ASCII performance is bad. This is unavoidable for tiny iterations.
Example is included to show how to work around this.
Description:
Iter now iterates per boundary/segment. It returns a slice of bytes that
either points to the input bytes, the internal decomposition strings,
or the small internal buffer that each iterator has. In many cases, copying
bytes is avoided.
The method Seek was added to support jumping around the input without
having to reinitialize.
Details:
- Table adjustments: some decompositions exist of multiple segments.
Decompositions that are of this type are now marked so that Iter can
handle them separately.
- The old iterator had a different next function for different normal forms
that was assigned to a function pointer called by Next.
The new iterator uses this mechanism to switch between different modes
for handling different type of input as well. This greatly improves
performance for Hangul and ASCII. It is also used for multi-segment
decompositions.
- input is now a struct of sting and []byte, instead of an interface.
This simplifies optimizing the ASCII case.

the need to decompose characters for the majority of cases. This considerably
speeds up collation while increasing the table size minimally.
To detect non-normalized strings, rather than relying on exp/norm, the table
now includes CCC information. The inclusion of this information does not
increase table size.
DETAILS
- Raw collation elements are now a struct that includes the CCC, rather
than a slice of ints.
- Builder now ensures that NFD and NFC counterparts are included in the table.
This also fixes a bug for Korean which is responsible for most of the growth
of the table size.
- As there is no more normalization step, code should now handle both strings
and byte slices as input. Introduced source type to facilitate this.
NOTES
- This change does not handle normalization correctly entirely for contractions.
This causes a few failures with the regtest. table_test.go contains a few
uncommented tests that can be enabled once this is fixed. The easiest is to
fix this once we have the new norm.Iter.
- Removed a test cases in table_test that covers cases that are now guaranteed
to not exist.

Before this CL, defining the variable worked fine, but then when

An error during the compilation can be more precise
than an error at link time.
For 'func init', the error happens always: you can't forward
declare an init func because the name gets mangled.
For other funcs, the error happens only with the special
(and never used by hand) -= flag, which tells 6g the
package is pure go.
The go command now passes -= for pure Go packages.

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.

remove zerostack compiler experiment; will do at link time instead
««« original CL description
cmd/gc: add GOEXPERIMENT=zerostack to clear stack on function entry
This is expensive but it might be useful in cases where
people are suffering from false positives during garbage
collection and are willing to trade the CPU time for getting
rid of the false positives.
On the other hand it only eliminates false positives caused
by other function calls, not false positives caused by dead
temporaries stored in the current function call.
The 5g/6g/8g changes were pulled out of the history, from
the last time we needed to do this (to work around a goto bug).
The code in go.h, lex.c, pgen.c is new but tiny.

This makes Marshal handle fields marked ",any" instead of ignoring
them. That makes Marshal more symmetrical with Unmarshal, which seems
to have been a design goal.
Note some test cases were changed, because this patch changes
marshalling behavior. I think the previous behavior was buggy, but
there's still a backward-compatibility question to consider.
