| ||
| 03:57 | Add elimination of LOAD-STORE redundancy - don't put into the callframe a value that we just got from there. This check may or may not be useful; the test suite exercises it but only on 'set x '. It does come up in other langauges. Leaf check-in: 933c8a03f0 user: kbk tags: kbk-refactor-callframe | |
|
2020-01-09
| ||
| 21:56 | Handle 'invokeExpanded'. Restore the ability to remove references to the callframe when calling compiled functions or builtins that don't use it. check-in: b54d2746cb user: kbk tags: kbk-refactor-callframe | |
|
2020-01-08
| ||
| 03:12 | Handle correctly the case where there is 'moveFromCallFrame' the same variable from the same callframe on two converging execution paths. check-in: c3e7daa5b9 user: kbk tags: kbk-refactor-callframe | |
|
2020-01-07
| ||
| 03:18 | Fix incorrect analysis of avail vars at a merge point. All tests but poly1305 pass. Still mislinkage of call frames in direct operation tests. check-in: 7ab1ef546d user: kbk tags: kbk-refactor-callframe | |
|
2020-01-05
| ||
| 20:51 | Calculate effect of 'invoke' on variable analysis. Not yet 100% correct - breaks six additional test cases. check-in: 0fdceaac26 user: kbk tags: notworking, kbk-refactor-callframe | |
| 05:51 | Liveness analysis of variables in the callframe, enabling store-store and dead-store optimizations. Build is working only because poly1305::compute is commented out. check-in: e392a97b1a user: kbk tags: kbk-refactor-callframe | |
|
2020-01-04
| ||
| 00:17 | Refine callframe effect of direct operations check-in: 6205ad764a user: kbk tags: kbk-refactor-callframe | |

|
2020-01-03

| 23:22 | Refine the callframe effect of 'variable' check-in: b0449c3905 user: kbk tags: kbk-refactor-callframe | |
| 23:19 | refine callframe effect of 'nsupvar' and 'upvar' check-in: 3c1db65142 user: kbk tags: kbk-refactor-callframe | |
| 22:51 | Restore the logic that, after a catch, requires any globals that are aliased in the callframe to be reloaded lest they alias errorInfo or errorCode. Also propagate that requirement out to callers of the proc containing the catch. check-in: 0acf314fef user: kbk tags: kbk-refactor-callframe | |
| 20:47 | Update a few missing ops in quadcodes.txt check-in: fedf0433fc user: kbk tags: kbk-refactor-callframe | |
| 19:48 | Patch out poly1305::compute for now - segfault! - and break out the 'vartest' tests. check-in: 13b2b5767e user: kbk tags: notworking, kbk-refactor-callframe | |
|
2020-01-02
| ||
| 21:12 | Make the poly1305 routines explicit in the tester check-in: 7466722d0e user: kbk tags: kbk-refactor-callframe | |
| 20:48 | Detect that 'invoke' preserves some callframe variables. Add buffer flushing so that the identity of a test is reported before a crash. Remove some redundant test invocations. check-in: 65069fda8f user: kbk tags: notworking, kbk-refactor-callframe, current | |
| 18:50 | Add consistency check that callframes are linked correctly before generating speculative phi operations. check-in: b541601fb1 user: kbk tags: kbk-refactor-callframe | |

|
2020-01-01
| ||
| 23:51 | Don't abort all the performance tests because one test throws an error. Make the 'arrayExists' operation consistent with 'extractArray' and 'extractScalar' throughout (there were bad optimizations). Revert a misguided change to 'dict update' that was actually an attempt to work around the 'extractScalar' inconsistency. check-in: 5b6ac87fe8 user: kbk tags: kbk-refactor-callframe | |
|
2019-12-31
| ||
| 17:32 | Separate exists and doesn't-exist paths in 'translate' of read-modify-write operations. Fix overeager elimination of 'extractArray'. Move 'partialredundancy' off to its own specializer step, since 'tidy' passes may NOT introduce new variables. Only 'lsetest' is now failing. check-in: 09d85d696a user: kbk tags: notworking, kbk-refactor-callframe | |
| 00:10 | Finish up elision of 'moveFromCallFrame' in the simpler cases. check-in: bbb81cb21e user: kbk tags: notworking, kbk-refactor-callframe | |
|
2019-12-30
| ||
| 03:14 | Provide a hook on which to hang speculative phi generation. check-in: f635c5689f user: kbk tags: notworking, kbk-refactor-callframe | |
| 01:50 | Peephole optimization of 'moveFromCallFrame' when the value in the callframe is known. (Will be much more effective once more instructions are analyzed: notably 'invoke' and 'phi'.) check-in: 188df1dde4 user: kbk tags: notworking, kbk-refactor-callframe | |
|
2019-12-27
| ||
| 23:01 | Add the basic framework for forward analysis of available callframe variables check-in: 85ea960b98 user: kbk tags: notworking, kbk-refactor-callframe | |
|
2019-12-01
| ||
| 20:32 | Remove remnants of unused 'startCatch' and 'callFrameNop' instructions, and the pass that removes them (since they're never emitted, they're never removed). check-in: c2d0f14a30 user: kbk tags: kbk-refactor-callframe | |
| 20:21 | Remove one false start at callframe analysis, and add some stubs for another attack on the problem. check-in: 5741a8ab06 user: kbk tags: kbk-refactor-callframe | |
|
2019-11-26

| 09:58 | Starting to support 8.7's arrays with defaults Leaf check-in: e7a8c3f643 user: dkf tags: dkf-array-default | |
|
2019-11-24
| ||
| 01:15 | Modify varargs to not rewrite if the target procedure is not being compiled. This change restores poly1305 to compilability. check-in: e86f7b8518 user: kbk tags: kbk-refactor-callframe | |
|
2019-11-23
| ||
| 23:21 | Merge trunk and return to mostly-working status. Two test cases commented away: magicreturn and poly1305. check-in: 824a7974cf user: kbk tags: kbk-refactor-callframe | |
| 23:02 | merge trunk check-in: c3fc2d4137 user: kbk tags: notworking, kbk-refactor-callframe | |

| 22:29 | Merge in refactoring of two operations, directIsArray and directMakeArray, that interact with the callframe and were missed on the first go. Leaf check-in: 7a21900824 user: kbk tags: trunk | |

|
2019-11-18
| ||
| 20:29 | Stop confusion over what is being mapped to what. Merge loops that should be merged. check-in: a4634d05b6 user: dkf tags: dkf-cheaper-autoconvert | |

|
2019-11-15
| ||
| 23:09 | Change return type of directUnset and directUnsetArray from CALLFRAME FAIL to CALLFRAME FAIL BOOLEAN, because void values aren't handled well in the code issuer. Simply discard the unused result. check-in: 731e9cafc6 user: kbk tags: kbk-refactor-directops | |

Next up: fix the dictest tests involving 'dict update', lsetest, and re-add support for direct ops. check-in: 27339e7e0c user: kbk tags: notworking, kbk-refactor-callframe | |

| 03:46 | Further development of varargs. Note that the invocation sequence is much, much simpler than it used to be, so 'invoke.tcl' is no more. check-in: 90e908dae3 user: kbk tags: notworking, kbk-refactor-callframe | |

2019-01-01
| ||
| 23:06 | Update quadcode generation and documentation so that 'direct' operations refer to the callframe (which is necessary in the event that they are emitted to deal with double-dereference). CODE ISSUER IS NOT YET UPDATED TO COPE WITH THE CHANGE. check-in: 104debc734 user: kbk tags: notworking, kbk-refactor-callframe | |

| 23:19 | Integrate kbk-jumpthread: replace the node-by-node splitting with a single pass that identifies many threading opportunities and also reduces the number of splits. Eliminate the old nodesplit pass, and the renameTemps pass, which is no longer required. check-in: a934a75e1f user: kbk tags: trunk | |

2018-12-16

| 05:37 | Rewrite pre_insert and pre_phi_translate to NOT use a persistent cache. The missing piece in VanD04 is that pre_insert must call pre_phi_translate for all the anticipated expressions first, and then use the dictionary that results for the translated values. There are still further bugs, but we're over this hump at least. check-in: 0bbe5a5dd3 user: kbk tags: notworking, kbk-pre | |

| 05:08 | Stop constant folding from leaving dead code behind, Add a test for simple nested iterations, using [lmap]. Temporarily patch 'foreach' operations from being hoistable - I don't think this will be necessary, but it's tickling other bugs. Make translation of values across a phi work if one of the inputs to the phi is a literal. Put 'bbidom' and 'bblevel' directly after dead code elimination, because virtually everything depends on having dominators, which deadcode destroys. check-in: 4f50ed77b2 user: kbk tags: notworking, kbk-pre | |

Corrected du-chain mismanagement in callframe.tcl (deleting moveToCallFrame), copyprop.tcl (deleting any quads), uselessphis (deleting anything), and narrow.tcl (cleanupNarrow, deleting anything). NOT WORKING: During node splitting, at least 'flightawarebench', 'msrange', 'bug7c59', and 'cse-caller' are still coming out with mismanaged chains. Improved auditing in the 'tidy' pass of the transformer, and made it less aggressive about rechecking everything. NOT WORKING: in the 'wordcounter2' test case, it's missing at least one invocation of 'initArrayIfNotExists' because we're falling into the code gen in 'compile.tcl' for initArrayIfNotExists(ARRAY). Advanced partial redundancy elimination to 'code complete' status. The stuff surrounding it is in bad enough shape at the moment that it is far from tested, and known not to be working for everything, but is patched out at the moment. check-in: 02ab4301aa user: kbk tags: notworking, kbk-pre | |

Adopt a new theory of SSA repair that reconstructs SSA for specific variables by renaming only the affect variable and tracing uses upward to their reaching defs, adding phis as necessary. Temporarily bypass node splitting/jump threading, because it is not yet using the new approach to SSA repair. New algorithms should not require Conventional SSA for the repairs, so efforts to preserve it have been abandoned. check-in: f7580cf32d user: kbk tags: kbk-ssa-repair | |
