*	#5057: the peepholer no longer optimizes subscription on unicode literals ↵	Ezio Melotti	2012-11-04	1	-6/+7
\| \| \| \|	(e.g. u"foo"[0]) in order to produce compatible pyc files between narrow and wide builds.
*	Issue #5057: fix a bug in the peepholer that led to non-portable pyc files ↵	Ezio Melotti	2011-04-15	1	-0/+18
\| \| \| \|	between narrow and wide builds while optimizing BINARY_SUBSCR on non-BMP chars (e.g. u"\U00012345"[0]).
*	#7092 - Silence more py3k deprecation warnings, using ↵	Florent Xicluna	2010-03-21	1	-11/+14
\| \| \| \|	test_support.check_py3k_warnings() helper.
*	use assert[Not]In where appropriate	Ezio Melotti	2010-01-23	1	-30/+30

*	Reverting the Revision: 77368. I committed Flox's big patch for tests by	Senthil Kumaran	2010-01-08	1	-17/+11
\| \| \| \|	mistake. ( It may come in for sure tough)
*	Fixing - Issue7026 - RuntimeError: dictionary changed size during iteration. ↵	Senthil Kumaran	2010-01-08	1	-11/+17
\| \| \| \|	Patch by flox
*	convert usage of fail* to assert*	Benjamin Peterson	2009-06-30	1	-30/+30
\|
*	Backport r69961 to trunk, replacing JUMP_IF_{TRUE,FALSE} with	Jeffrey Yasskin	2009-02-28	1	-6/+5
\| \| \| \| \| \|	POP_JUMP_IF_{TRUE,FALSE} and JUMP_IF_{TRUE,FALSE}_OR_POP. This avoids executing a POP_TOP on each conditional and sometimes allows the peephole optimizer to skip a JUMP_ABSOLUTE entirely. It speeds up list comprehensions significantly.
*	Fix embarrassing typo and fix constantification of None	Raymond Hettinger	2007-03-02	1	-0/+5
\|
*	Update the peephole optimizer to remove more dead code (jumps after returns)	Neal Norwitz	2006-10-14	1	-0/+35
\| \| \| \|	and inline jumps to returns.
*	Teach the peepholer to fold unary operations on constants.	Raymond Hettinger	2005-02-20	1	-0/+19
\| \| \| \| \|	Afterwards, -0.5 loads in a single step and no longer requires a runtime UNARY_NEGATIVE operation.
*	Remove set conversion optimization test (backed out of Python/compile.c in rev.	Brett Cannon	2005-02-10	1	-11/+0
\| \| \| \|	2.344).
*	Adopt Skip's idea to optimize lists of constants in the context	Raymond Hettinger	2005-02-07	1	-1/+2
\| \| \| \|	of a "in" or "not in" test.
*	Transform "x in (1,2,3)" to "x in frozenset([1,2,3])".	Raymond Hettinger	2005-02-06	1	-0/+10
\| \| \| \| \|	Inspired by Skip's idea to recognize the throw-away nature of sequences in this context and to transform their type to one with better performance.
*	Do not fold a constant if a large sequence will result.	Raymond Hettinger	2005-01-26	1	-0/+4
\| \| \| \|	Saves space in the presence of code like: (None,)*10000
*	Remove test for BINARY_DIVIDE.	Raymond Hettinger	2005-01-07	1	-1/+0
\|
*	Teach the peephole optimizer to fold simple constant expressions.	Raymond Hettinger	2005-01-02	1	-0/+28
\|
*	Maintain peepholer's cumlc invariant by updating the running total	Raymond Hettinger	2004-11-02	1	-3/+5
\| \| \| \| \| \|	everytime a LOAD_CONSTANT is encountered, created, or overwritten. Added two tests to cover cases affected by the patch.
*	SF bug #1053819: Segfault in tuple_of_constants	Raymond Hettinger	2004-10-26	1	-0/+17
\| \| \| \| \| \| \|	Peepholer could be fooled into misidentifying a tuple_of_constants. Added code to count consecutive occurrences of LOAD_CONST. Use the count to weed out the misidentified cases. Added a unittest.
*	SF patch #1031667: Fold tuples of constants into a single constant	Raymond Hettinger	2004-09-22	1	-3/+13
\| \| \| \| \| \| \| \|	Example: >>> import dis >>> dis.dis(compile('1,2,3', '', 'eval')) 0 0 LOAD_CONST 3 ((1, 2, 3)) 3 RETURN_VALUE
*	Whitespace normalization.	Tim Peters	2004-08-26	1	-5/+5

*	SF Patch #1013667: Cleanup Peepholer Output	Raymond Hettinger	2004-08-23	1	-0/+104
	* Make a pass to eliminate NOPs. Produce code that is more readable, more compact, and a tiny bit faster. Makes the peepholer more flexible in the scope of allowable transformations. * With Guido's okay, bumped up the magic number so that this patch gets widely exercised before the alpha goes out.
