Age	Commit message (Collapse)	Author
2014-05-19	add testcases for last few commits	Alon Zakai

2014-05-13	conditionalize in all boolean-emitting expressions	Alon Zakai

2014-05-13	update heuristic	Alon Zakai

2014-05-13	conditionalize when it can avoid costly side-effect free code	Alon Zakai

2014-02-04	do not apply de-morgan's laws on floats, nans break them	Alon Zakai

2014-02-03	handle fround in optimizing out of tempDoublePtr	Alon Zakai

2013-12-19	Optimize away masks on stores to HEAP8 and HEAP16.	Dan Gohman
	Optimize HEAP8[i] = x & 255 to HEAP8[i] = x, and similar for HEAP16.
2013-10-03	update js optimizer tests	Alon Zakai

2013-07-17	consolidate simplifyExpressions to one pass that happens before closure, ↵	Alon Zakai
	where simplifyNotComps is guaranteed to be valid
2013-07-14	do not eliminate away tempDoublePtr uses that are alignment fixes; fixes #1375	Alon Zakai

2013-07-13	avoid creating ~~~ (from ~~ ^ -1) which is confusing for asm given the role ↵	Alon Zakai
	of ~~
2013-07-08	Add '!==' as a comparison operator.	Dan Gohman

2013-07-08	Xor optimizations.	Dan Gohman
	Optimize x^-1 to ~x; this comes up because LLVM does not have a bitwise negate operator. Optimize x&1^1 to !x; this comes up because of how LLVM lowers C++ bool variables. Also, add an optimization to simplifyExpressionsPre to eliminate \|0 from '~' expressions in more cases.
2013-07-01	Optimize (x<y)&1	Dan Gohman
	Add an optimization to simplifyExpressionsPre to replace (x<y)&1 with x<y if possible. This comes up frequently in C++ with bool variables.
2013-06-27	do not collapse & inside a FUNCTION_TABLE call, we need the mask	Alon Zakai

2013-06-21	update tests	Alon Zakai

2013-06-19	fix bug with reducing f()\|0\|const	Alon Zakai

2013-06-19	keep \|0 on function calls, allow other bitwise ops on heap accesses etc.	Alon Zakai

2013-06-19	keep coercions on heap accesses and function calls, but fully optimize them ↵	Alon Zakai
	otherwise
2013-06-08	only remove seq\|0 when seq is an assign value	Alon Zakai

2013-06-08	remove unneeded outside \|0 when a sequence ends in a safe bitop	Alon Zakai

2013-06-08	optimize away bitcasts to variables that will only be used in an assign to ↵	Alon Zakai
	the parallel heap type
2013-06-07	improve tempDoublePtr elimination and only run analysis when necessary	Alon Zakai

2013-06-07	eliminate bitcasts of immediately loaded values	Alon Zakai

2013-06-07	optimize some HEAP32 expressions, including some unnecessary bitcasts ↵	Alon Zakai
	through tempDoublePtr
2013-05-22	Optimize (x&A)<<B>>B.	Dan Gohman
	Add an optimization to simplifyExpressionsPre to replace (x&A)<<B>>B with X&A if possible. This comes up frequently in C++ with bool variables.
2013-04-20	optimize HEAPU?8[..] << 24 >> 24 and similar	Alon Zakai

2013-03-09	move asm return adding test to right place	Alon Zakai

2013-03-09	remove coercions on asm function calls that have no capturing variables	Alon Zakai

2013-02-04	optimize num >> num in js optimizer, necessary for asm now that we do not do ↵	Alon Zakai
	shift optimization there
2013-01-18	fix simplyExpressions bug with removing too many \|0s	Alon Zakai

2013-01-08	optimize \|,& on constants	Alon Zakai

2013-01-08	improve \|0 removal in asm mode a little	Alon Zakai

2013-01-08	keep a coercion right on top of heap accesses in asm mode	Alon Zakai
