Starting to work on being able to write (most of) the stdlib in C; lots of things are not yet working... check-in: 63f2d78960 user: dkf tags: stdlib-in-c

2019-02-02
18:14
Expansion... sort of Leaf check-in: 721be90d96 user: dkf tags: list-and-dict-types
2019-01-29
13:19
Fix misorderered scalar check/copy to result check-in: 36e8177510 user: kbk tags: notworking, kbk-refactor-callframe
02:00
Fix translation bugs that broke [dict] tests check-in: ab6da27502 user: kbk tags: notworking, kbk-refactor-callframe
2019-01-23
02:12
Add conversion to IMPURE ZEROONE INT, needed in booltest. Keep code motion from messing with the callframe for now. Patch out the handful of remaining tests that abort. 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
2019-01-22
02:52
Restore the 'timings' list - if 'transform' doesn't produce it, there's a crash. check-in: 3e49a05889 user: kbk tags: notworking, kbk-refactor-callframe
02:36
Run dead code elimination before copy propagation because copyprop explodes otherwise. check-in: 9e16d3b8d6 user: kbk tags: notworking, kbk-refactor-callframe
02:35
Bug fixes to make all the 'expandtest' cases work check-in: 4f7b3a4d01 user: kbk tags: notworking, kbk-refactor-callframe
2019-01-21
22:33
Enough partial implementation for expandtest::test1-test3 check-in: 89030dcc42 user: kbk tags: notworking, kbk-refactor-callframe
19:45
Fix mislinking of phi operations on the error branch of 'invoke' check-in: 407e1ef055 user: kbk tags: notworking, kbk-refactor-callframe
18:14
Enough changes to get through first two 'expandtest' tests check-in: 5557b1e592 user: kbk tags: notworking, kbk-refactor-callframe
2019-01-18
04:22
Add the final processing in 'varargs' - next, emit the error path. check-in: 305328fa6b user: kbk tags: notworking, kbk-refactor-callframe
2019-01-16
02:30
More argument preparation code in 'varargs' check-in: 76b943ad4a user: kbk tags: notworking, kbk-refactor-callframe
2019-01-14
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
2019-01-13
15:43
Clean out dead 'exists.tcl' source check-in: f283d28ebd user: kbk tags: notworking, kbk-refactor-callframe
15:38
Merge the (not-working) vararg reform branch. It appears that both these tasks need to be attacked at the same time because the changes are tightly interwoven. check-in: 05c93c9cc5 user: kbk tags: notworking, kbk-refactor-callframe
2019-01-09
01:52
Add support for compiled procs that alter the callframe, then fail. check-in: 30d6a54fdb user: kbk tags: notworking, kbk-refactor-callframe
2019-01-08
04:17
Fix more trivial errors in 'translate' and missing cases in code gen check-in: fba0ec7241 user: kbk tags: notworking, kbk-refactor-callframe
2019-01-05
22:48
Generate only one moveFromCallFrame per bytecode instruction check-in: 9dbaca7922 user: kbk tags: notworking, kbk-refactor-callframe
2019-01-02
16:22
A little bit less wrong. check-in: 75fd3b203e user: dkf tags: list-and-dict-types
02:20
Oops, one extra callframe ref in 'callframe-error-quads' check-in: cdc4d10e86 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
21:57
Move callframe moves to the actual points where callframe values are moved. They can then be optimized by avaiability and liveness analysis. check-in: dbd9571178 user: kbk tags: notworking, kbk-refactor-callframe
2018-12-29
21:00
Keep dictionary iterations out of the callframe - they can never be addressed by upvar check-in: ea7b788fb4 user: kbk tags: kbk-refactor-callframe
20:26
Open a branch for some experiments on refactoring callframe operations check-in: 7454a5228c user: kbk tags: kbk-refactor-callframe
2018-12-27
19:47
Add 'buiilder.tcl' inadvertently omitted from previous commit Closed-Leaf check-in: 2e3b3ea76f user: kbk tags: notworking, kbk-refactor-varargs
19:44
Very rough beginning of a refactored 'varargs' pass check-in: 7c9d400e5e user: kbk tags: notworking, kbk-refactor-varargs
04:12
Eliminate the 'isBoolean' instruction in favour of using the type checking machinery check-in: 0718166269 user: kbk tags: trunk
04:09
Eliminate the 'isBoolean' opcode in favour of 'instanceOf', to allow for type inferemce based on tryCvtToBoolean Closed-Leaf check-in: bd009801ca user: kbk tags: kbk-isBoolean
03:53
Open a branch for rework of 'isBoolean' so that it informs type inference check-in: 2a34883328 user: kbk tags: kbk-isBoolean
2018-12-18
15:12
OOPS: remove 'source' of unused file check-in: 3bf74c48dc user: kbk tags: trunk
02:32
Add a long-forgotten 'specializer.md' discussing what the specializer does. check-in: 7bd4d23ac9 user: kbk tags: trunk
2018-12-17
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
23:13
result, returnCode, returnOptions must be split into FAIL and non-FAIL paths because the backend isn't prepared to deal with all combinations of FAIL + someOtherType. Closed-Leaf check-in: 94358b53ea user: kbk tags: kbk-jumpthread
22:08
Finish jump threading - actually do the block duplication and redirection of jumps. Add the logic for SSA deconstruction (required by jump threading) and make SSA construction work with the deconstructed result. check-in: a41b93130e user: kbk tags: notworking, kbk-jumpthread
2018-12-16
05:18
Add constant folding for unary +. It probably ought to be folded out altogether, since it serves only to trigger type checking. Add an outline of the actual process of jump threading once the threads have been determined. check-in: c388c8737b user: kbk tags: notworking, kbk-jumpthread
04:55
Add a 'cos2' test case to illustrate the cost of non-numeric ordering comparisons check-in: 86167d6917 user: kbk tags: notworking, kbk-jumpthread
04:43
Finish forward analysis in the jump threading pass. check-in: dc90afa15d user: kbk tags: notworking, kbk-jumpthread
2018-12-10
04:51
Remove vestiges of the old node splitter from 'inline.tcl'. Make console dribble in 'jumpthread.tcl' contingent on debug-jumpthread. check-in: fd2ea3e6f1 user: kbk tags: notworking, kbk-jumpthread
