| | | | | | | | | | 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.

* compiler.transformer: correct lineno attribute when possibleJeremy Hylton2004-09-072-405/+316
| | | | | | | | | | | | | | | | SF patch #1015989 The basic idea of this patch is to compute lineno attributes for all AST nodes. The actual implementation lead to a lot of restructing and code cleanup. The generated AST nodes now have an optional lineno argument to constructor. Remove the top-level asList(), since it didn't seem to serve any purpose. Add an __iter__ to ast nodes. Use isinstance() instead of explicit type tests. Change transformer to use the new lineno attribute, which replaces three lines of code with one. Use universal newlines so that we can get rid of special-case code for line endings. Use lookup_node() in a few more frequently called, but simple com_xxx methods(). Change string exception to class exception.

* SF patch #872326: Generator expression implementationRaymond Hettinger2004-05-194-0/+259
| | | | | | | | | | | | | | (Code contributed by Jiwon Seo.) The documentation portion of the patch is being re-worked and will be checked-in soon. Likewise, PEP 289 will be updated to reflect Guido's rationale for the design decisions on binding behavior (as described in in his patch comments and in discussions on python-dev). The test file, test_genexps.py, is written in doctest format and is meant to exercise all aspects of the the patch. Further additions are welcome from everyone. Please stress test this new feature as much as possible before the alpha release.

* SF patch [ 597919 ] compiler package and SET_LINENOJeremy Hylton2002-12-314-44/+69
| | | | | | | | | | | | | | | | | 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.

* Fix com_arglist() and update grammar fragment.Jeremy Hylton2002-04-191-6/+3
| | | | | | | | | | | | | | | | | SF bug #522264 reported by Evelyn Mitchell. The code included a comment about "STAR STAR" which was translated into the code as the bogus attribute token.STARSTAR. This name never caused an attribute error because it was never retrieved. The code was based on an old version of the grammar that specified kwargs as two tokens ('*' '*'). I checked as far back as 2.1 and didn't find this production. The fix is simple, because token.DOUBLESTAR is the only token allowed. Also update the grammar fragment in com_arglist(). XXX I'll bet lots of other grammar fragments in comments are out of date, probably in this module and in compile.c.

* Vastly improved stacksize calculation.Jeremy Hylton2001-10-171-18/+51
| | | | | | | | | | | | | | | | | | | | | There are now no known cases where the compiler package computes a stack depth lower than the one computed by the builtin compiler. (To achieve this state, we had to fix bugs in both compilers :-). The chief change is to do the depth calculations with respect to basic blocks. The stack effect of block is calculated. Then the flow graph is traversed using breadth-first search to find the max weight path through the graph. Had to fix the StackDepthTracker to calculate the right info for several opcodes: LOAD_ATTR, CALL_FUNCTION (and friends), MAKE_CLOSURE, and DUP_TOPX. XXX Still need to handle free variables in MAKE_CLOSURE. XXX There are still a lot of places where the computed stack depth is larger than for the builtin compiler. These won't cause the interpreter to overflow the frame, but they waste space.

Each corresponds to a compilation mode. THe AbstractCompileMode instances in turn delegate to CodeGeneration subclasses specialized for their particular functions -- ModuleCodeGenerator, ExpressionCodeGeneration, InteractiveCodeGenerator.

* Last set of change to get regression tests to passJeremy Hylton2001-09-173-5/+10
| | | | | | | | | | | Remove the only test in the syntax module. It ends up that the transformer must handle this error case. In the transformer, check for a list compression in com_assign_list() by looking for a list_for node where a comma is expected. In pycodegen.compile() re-raise the SyntaxError rather than catching it and exiting
