From 399bb146cc0bb0c548cd0b50e51fb9aa29a7900c Mon Sep 17 00:00:00 2001 From: Dibyendu Majumdar Date: Mon, 15 Jan 2024 00:13:44 +0000 Subject: Implement break and continue (#55) * #52 Update chapter8 to align with chapter7 * #52 Update chapter8 to align with chapter7 * #52 Fix spacing * #51 get started on break and continue * #51 get started on break and continue * #51 more on break and continue * #51 more on break and continue * #51 more on break and continue * #51 more on break and continue * #51 more on break and continue * #51 more on break and continue * break & continue scopes are made lazily, and merged into as discovered Drop ContBreak. Drop ScopeNode.addScope. Add a simple mergeScopes. Simplify Region.inProgress; drop from child classes, use in Region. Add a ConstantNode.XCONTROL shortcut. * Fix some regressions * Error on dead code after break/continue * A more robust dead-def check * Fix for dead loop-back path * Fix scope shadowing bug with continue/break Turn on LAZY phis by default; fix minor golden test results * Fix a case with both break & continue * #51 more on break and continue * #51 more on break and continue * #51 more on break and continue * #51 fix erroneous push of scope * #51 fix import * #51 update test expected results * #51 Start Chapter8 writeup * #51 Start Chapter8 writeup * #51 _scope needs killing after continue * Add graph evaluator (#56) * #51 wip writeup * #51 wip writeup * #51 wip writeup * #51 wip writeup * #51 wip writeup * #51 update code comments / add assertion * #51 revert assertion * #51 evaluate graph to verify test outcome * #51 add code snippets * #51 add examples * Cleanup README Comment for usefullness of true Loops. Try to distiguish `PhiNode` as the programming construct from `phi` as the mathematically SSA notation. Flow long lines. Remove LAZY flag, set as `true`. Fold up true tests. * minor comment * #51 Check _breakScope is not null when parsing break or continue to detect use outside of loop * #51 in parseComparison we need to move the op= version above the op version, since at this time using <= and >= does not work since they are parsed as > and < with a preceeding = which causes an error * #51 Update main README to link to chapter 8 * Remove useless test --------- Co-authored-by: Cliff Click Co-authored-by: XmiliaH <45106915+XmiliaH@users.noreply.github.com> --- chapter08/docs/build-graphs.sh | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'chapter08/docs/build-graphs.sh') diff --git a/chapter08/docs/build-graphs.sh b/chapter08/docs/build-graphs.sh index 73c39624..f660790b 100644 --- a/chapter08/docs/build-graphs.sh +++ b/chapter08/docs/build-graphs.sh @@ -1,3 +1,6 @@ -dot -Tsvg 07-graph1.gv > 07-graph1.svg +dot -Tsvg 08-graph1.gv > 08-graph1.svg +dot -Tsvg 08-graph2.gv > 08-graph2.svg +dot -Tsvg 08-graph3.gv > 08-graph3.svg + -- cgit v1.2.3
