* chapter9
* merge fixes to chapter8
* Ch 9 notes
* Ch 9 work
Add a Iterate phase, after parsing.
Add a Worklist with fast dup removal & rand pull.
Add a Node.iter() call which returns progress or null. Peephole calls it. Iter() also asserts that Types make monotonic progress.
Intern all types, so we can do a cheap/easy "isa" test.
* GVN
* rename temporarily
* Apply Cliff's worklist changes
* Apply Cliff's GVN changes
* Revert "GVN"
This reverts commit 9dc6db1cac7e40de4a58333cbc3c9c3e7c088e6f.
* Revert "Ch 9 work"
This reverts commit df5b74e6c017a4f237a5d1a550a83b40a7928876.
* Fix 3-1+2
Was computing as 3-(1+2) == 0, not 4 as expected.
Add tests.
Unlock in swap12.
* Missed some cut-n-paste changes
* Break up the test file per-chapter
* Fix keep-alive while looping expressions
Must "hook" LHS prior to calling peepholes
* Ch9 Region optimization
Bug fix, GVN hits 2 inProgress Loops
Bug fix lifetime tracking when parsing dead code
Bug fix debug find call
GraphViz post-iterate
* Readme overhaul
Progress on Ch 9 readme
* Fix bugs hashcode
Was relying on label() hashCode for Phi, Proj; since this is debug-only cannot be relied on. Proj relies on _idx field, Phi needs a !inProgress check.
* Constant nodes print "#" before con
* Add a farther neighbor check
Peeps that check more than the nearest neighbor register a dependency on the Node that failed them. Should that Node later change, the peep root is put back on the worklist and revisited.
* Fix addDeps assert
Unwind golden test print, print smarter.
Unlock edges in subsume
* Update README
* shuffle adddeps forward one
its needed again shortly in another test, so just cover it now
* Fix fuzzer bugs
Peep x+(-y) to x-y
Handle TOP inputs; didn't think it could happen before running an optimistic pass, but fuzzer proved me wrong.
Deleting an input can recursively delete the self-node.
When checking the compute() type assert, delay setting _type so the method can just be re-run in the debugger.
Missing addDep in Phi
Parser mis-handling stacked operators like "1+-2" or "1==!=<=<>=>2"
Make Work list deterministic between tests.
* Update fuzzer to run iterate (#62)
* Update fuzzer to run iterate
* Work seed is now reset by reset
* A few more fuzzer tests
Set _type in iter() even later, better debugging.
Handle dead active scopes in visiualizer.
Region ideal honors Loop invariants; finish Region ideal for single input; inProgress check is a little tighter.
Type.isConstant is true strictly for lattice centerline constants. Clean up TypeInteger.
ideaj warning removal
* Fix all fuzzer bugs
iter() does not call peep(), instead peep() is self-recursive. This allows Iterate() to call iter(), and not get into arbitrary recursive peep() changes that do not track on the worklist.
Div, Minus, If all monotonic.
Catch a bunch of progress issues.
Robustify IRPrinter and Iterate and Region ideal
* Reducer could run into an infinite loop (#63)
* Write up how the Evaluator works (#64)
* Write up how the Evaluator works
* Some small improvements and a slightly better wrap up.
* Series of fuzzer bugs.
Fix monotonicity for all data nodes.
Generic compute intercept for data nodes, check all inputs for TOP/BOTTOM, and again for IntDataNodes.
Fix general progress bug allow high Types as constants.
Fix progress Region 1-input has obvious idom.
Make shortcut for fuzzer; renames Fuzzer to not have "Test" in the class name.
Fix invert comment in TypeInteger
* All fuzzer tests pass
Turn off expensive assert accidentally turned on
CSE needs to join types.
Add a type join.
Missing dep in Phi
* More README
* Hacking alternative way to fix the type compute
* Node is no longer IntSupplier
Renamed Work to WorkList
Renamed Iterate to IterOptim
Renamed Node.iter() to Node.peepholeOpt()
WorkList expects elements to be of Node
* Add an example of GVN
* Rename the method depsClear to moveDepsToWorklist - to better capture what it actually does.
* Add a second example of GVN benefits
* Fix typo
* Add example of worklist opt
* Prepare to allow alternative post parse worklist opt
* Alternative WorkList opt that has following differences:
1. It does not require dependencies between nodes
2. It does not require calls from inside the Node class, and therefore runs totally independently as a post parse step.
3. It is simple
* Alternative WorkList opt that has following differences:
1. It does not require dependencies between nodes
2. It does not require calls from inside the Node class, and therefore runs totally independently as a post parse step.
3. It is simple
* The RPO list was incomplete as it only identified the subgraph accessible from the STOP node.
* Fix iter count
* Add test suggested by Xmilia
* Fix bug where after the region is peeped the phis get consistent number of inputs
* Fix bug where after the region is peeped the phis get consistent number of inputs
* Dump out stats on how many nodes we peepd during the post parse iterative opt.
* Make it easy to switch the IterOpt
* Use deps based worklist by default
* Sharper worklist add
* Copy across Cliff's changes
* Merge changes to Iterate
* Revert failing change
* Update readme
* Add comments / update docs to explain the patterns where we call addDep().
* As before, unconditionally made dep a dependent of region.
* Fix a lot of missing dep issues
Rename IterOptim -> IterPeeps
Some grammar changes in comments & readme
* Bump up fuzzer limits, more testing
Missing dep in idom calc in IfNode.
Missed idom cache clear on Region edit.
* Remove RPO based peeps
O(n^2) behavior
* Minor updates README
* fix compile bug
