* Remove the simple slicing API. All slicing is now done with slice objects.Thomas Wouters2007-08-301-14/+0
|
* Hide list comp variables and support set comprehensionsNick Coghlan2007-04-151-0/+1
|
* Implement PEP 3115 -- new metaclass syntax and semantics.Guido van Rossum2007-03-181-2/+3
| | | | | | | The compiler package hasn't been updated yet; test_compiler.py fails. Otherwise all tests seem to be passing now. There are no occurrences of __metaclass__ left in the standard library. Docs have not been updated.
* Bytes literal.Thomas Wouters2007-02-231-0/+1
|
* * Remove PRINT_ITEM(_TO), PRINT_NEWLINE(_TO) opcodes.Georg Brandl2007-02-091-4/+1
| | | | | | | * Fix some docstrings and one Print -> print. * Fix test_{class,code,descrtut,dis,extcall,parser,popen,pkg,subprocess,syntax,traceback}. These were the ones that generated code with a print statement. In most remaining failing tests there's an issue with the soft space.
* Patch #1550800: make exec a function.Georg Brandl2006-09-061-1/+0

* SF patch 1547796 by Georg Brandl -- set literals.Guido van Rossum2006-08-281-6/+7

* Remove the UNARY_CONVERT opcode (was used for backticks). Also bumped up theBrett Cannon2006-08-251-1/+0
| | | | import MAGIC number.
* INPLACE_DIVIDE is no longer necessary (INPLACE_TRUE_DIVIDE is used).Neal Norwitz2006-03-171-1/+1
|
* Get rid of last vestiges of BINARY_DIVIDE.Neal Norwitz2006-03-161-1/+1
|
* PEP 343 -- the with-statement.Guido van Rossum2006-02-271-7/+2
| | | | | | | | | | | | | This was started by Mike Bland and completed by Guido (with help from Neal). This still needs a __future__ statement added; Thomas is working on Michael's patch for that aspect. There's a small amount of code cleanup and refactoring in ast.c, compile.c and ceval.c (I fixed the lltrace behavior when EXT_POP is used -- however I had to make lltrace a static global).
* Install two code generation optimizations that depend on NOP.Raymond Hettinger2004-06-211-0/+1
| | | | Reduces the cost of "not" to almost zero.
* SF patch #910929: Optimize list comprehensionsRaymond Hettinger2004-03-071-0/+1
| | | | | Add a new opcode, LIST_APPEND, and apply it to the code generation for list comprehensions. Reduces the per-loop overhead by about a third.
* Replace backticks with repr() or "%r"Walter Dörwald2004-02-121-1/+1
| | | | From SF patch #852334.
* Revert the previous enhancement to the bytecode optimizer.Raymond Hettinger2003-04-241-2/+0
| | | | The additional code complexity and new NOP opcode were not worth it.
* Improved the bytecode optimizer.Raymond Hettinger2003-04-221-0/+2
| | | | | | | | | | | | | | * 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.
* new opcode module - extract opcode definitions from dis.py - eventuallySkip Montanaro2003-02-271-0/+188
