50 check-ins occurring around b9e2a13b963c8e9c.

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
17:46
remove some dead code in callframe.tcl check-in: a04a2b1d01 user: kbk tags: kbk-refactor-callframe
17:24
Need to write back to the stack after duplication. check-in: 4d3d8fac22 user: dkf 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
22:35
Merge trunk: a couple of ops that interact with the callframe and were missed while refactoring Leaf check-in: 19e26fa988 user: kbk tags: notworking, tcl_8_7_branch
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
22:24
directMakeArray interacts with the callframe Closed-Leaf check-in: 1f1e370993 user: kbk tags: kbk-refactor-directops
21:54
directIsArray interacts with the callframe check-in: a83ba5d5c3 user: kbk tags: kbk-refactor-directops
2019-11-22
20:31
Rejigger printing of results so that a crashing test can be identified more readily. check-in: c7402fd29e user: kennykb tags: notworking, tcl_8_7_branch
19:44
Initial changes to support differences in the Tcl 8.7 ABI check-in: 668d4221ed user: kennykb tags: notworking, tcl_8_7_branch
2019-11-19
13:05
Remove unused code Leaf check-in: 66cd584bff user: dkf tags: stdlib-in-c
03:52
Merge refactoring so that all direct operations interact correctly with the callframe. check-in: b9e2a13b96 user: kbk tags: trunk
03:48
Merge dkf's fixes that make type coercion run in a reasonable amount of time check-in: bf9270cd5a user: kbk tags: kbk-refactor-directops
00:48
Fix a couple of typos ('target' s/b 'targetinfo') - code now compiles the test suite again. Closed-Leaf check-in: d9095e2b40 user: kbk tags: dkf-cheaper-autoconvert
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
2019-11-16
14:39
Refactor stuff better (and more correctly) check-in: ebcd44d358 user: dkf tags: dkf-cheaper-autoconvert
14:28
Cheaper builder type conversion algorithm (untested) check-in: fe14e0068c 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
2019-11-13
03:55
directUnset interacts with the callframe and retuns CALLFRAME FAIL check-in: e06c6257c1 user: kbk tags: kbk-refactor-directops

01:52
directGet interacts with the callframe. (Has 'out' as well as 'in' because of traces). check-in: 22c7d8b278 user: kbk tags: kbk-refactor-directops
01:03
Add 'generate-callframe-op' method to quadcode translator to refactor 'directXXX' ops. check-in: e877e7f449 user: kbk tags: kbk-refactor-directops
2019-11-11
21:01
