3e0055f8c6 Merge ast-branch to head
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.

The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

1a7892924f Move the bytecode optimizer upstream so that its results are saved in pyc
files and not re-optimized upon import.  Saves a bit of startup time while
still remaining decoupled from the rest of the compiler.

As a side benefit, handcoded bytecode is not run through the optimizer
when new code objects are created.  Hopefully, a handcoder has already
created exactly what they want to have run.

(Idea suggested by Armin Rigo and Michael Hudson.  Initially avoided
 because of worries about compiler coupling; however, only the nexus
 point needed to be moved so there won't be a conflict when the AST
 branch is loaded.)

0ccff074cd This is Mark Russell's patch:
[ 1009560 ] Fix @decorator evaluation order

From the description:

Changes in this patch:

- Change Grammar/Grammar to require
newlines between adjacent decorators.

- Fix order of evaluation of decorators
in the C (compile.c) and python
(Lib/compiler/pycodegen.py) compilers

- Add better order of evaluation check
to test_decorators.py (test_eval_order)

- Update the decorator documentation in
the reference manual (improve description
of evaluation order and update syntax
description)

and the comment:

Used Brett's evaluation order (see
http://mail.python.org/pipermail/python-dev/2004-August/047835.html)

talk to him)

6c9e130524 - Removed FutureWarnings related to hex/oct literals and conversions
and left shifts.  (Thanks to Kalle Svensson for SF patch 849227.)
  This addresses most of the remaining semantic changes promised by
  PEP 237, except for repr() of a long, which still shows the trailing
  'L'.  The PEP appears to promise warnings for operations that
  changed semantics compared to Python 2.3, but this is not
  implemented; we've suffered through enough warnings related to
  hex/oct literals and I think it's best to be silent now.

1955fcf67a SF patch 763201: handling of SyntaxErrors in symbol table build
Fixes for three related bugs, including errors that caused a script to
be ignored without printing an error message.  The key problem was a bad
interaction between syntax warnings and syntax errors.  If an
exception was already set when a warning was issued, the warning could
clobber the exception.

The PyErr_Occurred() check in issue_warning() isn't entirely
satisfying (the caller should know whether there was already an
error), but a better solution isn't immediately obvious.

060641d511 Improved the bytecode optimizer.
* Can now test for basic blocks.
* Optimize inverted comparisions.
* Optimize unary_not followed by a conditional jump.
* Added a new opcode, NOP, to keep code size constant.
* Applied NOP to previous transformations where appropriate.

Note, the NOP would not be necessary if other functions were
added to re-target jump addresses and update the co_lnotab mapping.
That would yield slightly faster and cleaner bytecode at the
expense of optimizer simplicity and of keeping it decoupled
from the line-numbering structure.

for all hex/oct constants.

985eba53f5 Small function call optimization and special build option for call stats.
-DCALL_PROFILE: Count the number of function calls executed.

When this symbol is defined, the ceval mainloop and helper functions
count the number of function calls made.  It keeps detailed statistics
about what kind of object was called and whether the call hit any of
the special fast paths in the code.

Optimization:

When we take the fast_function() path, which seems to be taken for
most function calls, and there is minimal frame setup to do, avoid
call PyEval_EvalCodeEx().  The eval code ex function does a lot of
work to handle keywords args and star args, free variables,
generators, etc.  The inlined version simply allocates the frame and
copies the arguments values into the frame.

The optimization gets a little help from compile.c which adds a
CO_NOFREE flag to code objects that don't have free variables or cell
variables.  This change allows fast_function() to get into the fast
path with fewer tests.

I measure a couple of percent speedup in pystone with this change, but
there's surely more that can be done.

accb62b28e SF patch [ 597919 ] compiler package and SET_LINENO
A variety of changes from Michael Hudson to get the compiler working
with 2.3.  The primary change is the handling of SET_LINENO:

# The set_lineno() function and the explicit emit() calls for
# SET_LINENO below are only used to generate the line number table.
# As of Python 2.3, the interpreter does not have a SET_LINENO
# instruction.  pyassem treats SET_LINENO opcodes as a special case.

A few other small changes:
 - Remove unused code from pycodegen and pyassem.
 - Fix error handling in parsermodule.  When PyParser_SimplerParseString()
   fails, it sets an exception with detailed info.  The parsermodule
   was clobbering that exception and replacing it was a generic
   "could not parse string" exception.  Keep the original exception.

4c6c76559d Move three variables that are only used inside an if block into the block,
so the --disable-unicode build doesn't complain about unused variables.

53d58bb369 Further SET_LINENO reomval fixes. See comments in patch #587933.
Use a slightly different strategy to determine when not to call the line
trace function.  This removes the need for the RETURN_NONE opcode, so
that's gone again.  Update docs and comments to match.

Thanks to Neal and Armin!

Also add a test suite.  This should have come with the original patch...

b7164621fa Add warnings for arguments named None. All set. (I could add a
warning for 'global None', but that's either accompanied by an
assignment to None, which will trigger a warning, or not, in which
case it's harmless. :-)

63dd79ac04 Add warning for None used as keyword argument name in function call.
Still to do: function definition arguments (including *None and
**None).

b081e0c74c Minor cleanup of parsename() and parsestr(): the 'struct compiling *'
argument should be called 'c', like everywhere else.  Renamed a
complex variable 'c' to 'z' and moved it inside the only scope where
it's used.
