Build & Artifacts

The seed compiler writes reproducible structured outputs under:

  • build/tokens
  • build/ast
  • build/hir
  • build/mir
  • build/c
  • build/obj
  • build/bin
  • build/logs
  • build/diagnostics

Incremental build fingerprint includes source graph, stdlib files, and options.

Foundation Status (174-177)

174. Parallel Borrow Analysis

Borrow checking now includes a concurrency-oriented foundation layer:

  • Send/Sync-equivalent diagnostics for thread/send/sync misuse patterns
  • shared mutation checks across thread-like boundaries
  • thread ownership violation checks for escaped mutable references
  • race-risk diagnostics to flag potential missing happens-before edges

Primary implementation:

175. Advanced Optimization Passes

MIR transform foundation now tracks and reports advanced pass families:

  • inline candidates
  • loop simplification candidates
  • branch folding candidates
  • scalar replacement placeholders
  • dead store elimination candidates
  • value numbering placeholders

Primary implementation:

176. LLVM Backend Experimental

Experimental LLVM path is now selectable as llvm-exp:

  • LLVM IR emission via existing LLVM binding surface
  • debug metadata path preserved through profile options
  • optimization bridge (O0..Oz, LTO/PGO compatibility checks)
  • target lowering + linker/toolchain integration via LLVM toolchain status

Primary implementation:

  • src/vitte/compiler/backend/pipeline.vit
  • src/vitte/compiler/driver/compile.vit
  • src/vitte/compiler/backends/llvm_bindings/mod.vit
  • llvm_backend_experimental.md

177. Native ASM Backend

Minimal native assembly backend is now selectable as asm-native:

  • selection statement (x86_64 path)
  • virtual register allocation
  • calling convention marker (sysv-amd64)
  • stack-layout/prologue/epilogue verification signal
  • object text packaging for linker integration

Primary implementation:

  • src/vitte/compiler/backend/codegen/machine.vit
  • src/vitte/compiler/backend/codegen/mod.vit
  • src/vitte/compiler/backend/pipeline.vit
  • native_asm_backend.md
