- Replace all C code generation with LLVM IR (flat DFA model with
bb_ prefix labels to avoid SSA value name collisions)
- Remove c.min.js, add llvm.min.js highlight.js language definition
- Update shell.nix: gcc -> clang, remove sdl3/mesa deps
- Download LLVM Language Reference to docs/llvm/LangRef.html
- Rename #c-code to #ir-code in HTML, JS, and CSS
- Replace _generateIncludes with _generateLLVMDecls for extern
function declarations using LLVM_DECL_MAP
- Add string pool (CodeGen.allocString, stringGlobal, llvmStringArg)
for LLVM IR global string constants with getelementptr references
Replace the nested if-else branch-analysis architecture with a flat DFA
model using CodeGen.emitFlat — a single DFS walk emitting each block as
a C label followed by its code and gotos to all successors.
Removed:
- _branchDescendants / emitBranch / generateCallWithError
- _generateCallWithError, _noWalkNext, _genVisited
- generateNextCode, findBackEdges
- WCDecision._branchDescendants / _emitBranch / overridden generateCode
Added:
- CodeGen.emitFlat(entry) — flat DFS emit with labels + gotos
- WCBlock.generateFlowCode() — base emits gotos from wcNextFlow
- WCDecision.generateFlowCode() — if-goto / goto for decisions
- WCProcCall.generateFlowCode() — if (call != 0) goto err / goto ok
Output is flat — zero nested if-else for branch/error handling.
Tests use local out/ directory.
- Default colour now checks dataset.exitError instead of tagName === 'WC-END',
so success (exit 0) END blocks default to blue, error END blocks to red
- _selectByCode now also sets the HTML value attribute via setAttribute(),
ensuring cloneNode(true) preserves the formatted display value
- Add 4 regression tests for colour defaults, attribute sync, and clone value
- Replace if/else wrapping in WCProcCall.generateOwnCode with branch-aware
generation via _branchDescendants, _emitBranch, and _generateCallWithError
- Shared blocks (reachable from both error and success paths) now appear
only once after the if-block, avoiding deeply nested code
- Add 8 browser tests covering merge, decision passthrough, value style,
sequential calls, and shared-only error paths
- Increase template block spacing (16px -> 40px) for readability
- Add error WCEnd blocks to console and SDL3 templates with error-hook
connections to all failure-mode proc calls
- Hide editable WCProcCall input fields behind field-display spans,
matching existing algorithm-block convention
