Starting to work on being able to write (most of) the stdlib in C; lots of things are not yet working... Leaf check-in: 63f2d78960 user: dkf tags: stdlib-in-c
2019-07-21
19:56
Fix a bunch of Markdown formatting issues in callframe motion implementation plan Leaf check-in: ab89bbf879 user: kbk tags: kbk-refactor-callframe
2019-06-08

Remove cfRedundancy' header - added prematurely before method structure actually designed. check-in: 74a853f4cd user: kbk tags: kbk-refactor-callframe
2019-03-26
20:45
Oops - didn't commit images for callframe.md! check-in: a19796b4e5 user: kbk tags: kbk-refactor-callframe
2019-02-25

Fix some Markdown typos check-in: e1f3a19eb7 user: kbk tags: kbk-refactor-callframe

Start writing discussion of callframe management check-in: 50af9aa069 user: kbk tags: kbk-refactor-callframe
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 Leaf 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
