From 1a9cac97df063af82516ca35bde34fde62d24c56 Mon Sep 17 00:00:00 2001 From: Dibyendu Majumdar Date: Sat, 11 Nov 2023 23:17:22 +0000 Subject: Chapter 6 (#38) * #37 Create chapter 6 skeleton * #37 Revise type system - TOP, BOTTOM, CONTROL are now directly implemented in Type, XCONTROL is a new type and that's implemented directly too. We have a _type field that is like an enum. * #37 Revise Type.meet() - this is now final. Subclasses can override xmeet() which is protected but now handles simple types in Type itself. * #37 Basic test for peephole of CFG * #37 Revise compute of if * #37 Revise compute of if * #37 WIP peephole of If * #37 WIP peephole of If * #37 WIP peephole of If * #37 WIP peephole of If * #37 WIP peephole of If * #37 WIP fix the chars inserted by IntelliJ * #37 WIP Fix compute type in IfNode * #37 WIP Null check region inputs * #37 WIP Fix where we choose great grand parent instead of grand parent Add new test * #37 WIP More fixes and tests * #37 WIP Some minor adjustments * Cleanup folding dead IF tests Remove isDeadCtrl & just test for the constant. Remove DEAD_CTRL, doesn't properly reset between tests. Move keep/unkeep to Node. PhiNode has a proper compute() call. ProjNode ideal is a lot simpler. Region doesn't ever get a null. Move the mergeScopes Region peep till after all Phis are added. Type TOP and XCONTROL count as constants. TypeTuple gets a toString * #37 WIP Upate README * #37 WIP Region node should check if one of its inputs is a region that needs to be peepholed * #37 WIP If node should check if its ctrl input is a Region that has only 1 live input so can be peepholed * #37 WIP Further update to README to make the peephole logic clearer. Also discuss the relationship between Region and Phi nodes * Region removes dead input paths Remove region-folding in Return, If. Add a Makefile. Reformat triple-quote lines to be emacs-friendly. * StopNode idealize Return type sharpens to include control input. * Remove !=, >=, >; use Not and <, <=, == Fix bug mixing rotating different ops. Generalize Add fold constants; apply to Mul, EQ. Fix Div.copy * Fix bug rotating e.g. < or <= Peep is only valid for associative ops * #37 WIP Doc updates * Work over the Ch6 Readme Major issue: Region inputs align 1-to-1 with Phi inputs, but a Region can have zero to many Phis. When we lose a Region input (dead path), we need to lose the same inputs to each Phi - but we don't lose the Phis themselves, unless we're folding away down to the last live input. * Update chapter06/README.md Co-authored-by: Yichen Yan * Update chapter06/README.md Co-authored-by: Yichen Yan * #37 Backport type system changes to chapter 2 * #37 Backport type system changes to chapter 3 * #37 Backport type system changes to chapter 4 * #37 Backport type system changes to chapter 5 * #37 Merge chapter 5 updates from main. Remove language grammar module as we describe the grammar incrementally in each chapter. * #37 Chapter 6 doc updates - added visuals to show effects of CFG peephole * #37 Sync some updates to chapter 2 * #37 Sync some updates to chapter 3 * #37 Sync some updates to chapter 4 --------- Co-authored-by: Cliff Click Co-authored-by: Yichen Yan --- language/pom.xml | 79 -------------------------------------------------------- 1 file changed, 79 deletions(-) delete mode 100644 language/pom.xml (limited to 'language/pom.xml') diff --git a/language/pom.xml b/language/pom.xml deleted file mode 100644 index dbb4710e..00000000 --- a/language/pom.xml +++ /dev/null @@ -1,79 +0,0 @@ - - 4.0.0 - - com.seaofnodes - simple - 1.0 - - language-grammar - jar - SeaOfNodes Demo Simple Language Grammar - - UTF-8 - 21 - 21 - 1.22 - 4.11.1 - 4.13.2 - - - - org.antlr - antlr4-runtime - ${antlr.version} - jar - compile - - - - - - - org.apache.maven.plugins - maven-compiler-plugin - 3.10.1 - - - - - - org.antlr - antlr4-maven-plugin - ${antlr.version} - - true - true - - - - generate-sources - - antlr4 - - - - - - com.khubla.antlr - antlr4test-maven-plugin - ${antlr4test-maven-plugin.version} - - false - false - program - SimpleLanguage - com.seaofnodes.simple.antlr - examples/ - - - - - test - - - - - - - -- cgit v1.2.3
