- Auto-drop now only triggers for user-defined types explicitly marked
with @[Drop] on the struct declaration.
- Added move tracking in C backend to skip auto-drop for variables
that have been moved (via let y = x, return x, or assignment).
- Prevents double-free when ownership is transferred.
- Selfhost bootstrap loop verified: C output is deterministic.
- Add lib/Slice.bux with Slice<T> generic struct
- Fix C backend to recognize Slice/Slice* as generic types
- Use var instead of let for uninitialized Slice<T> locals
- Selfhost loop passes, tests pass
In @[Checked] functions, variables of type Array<T> automatically get
a defer Array_Free_T(&var) injected at declaration site. This ensures
Array values are freed when they go out of scope, preventing leaks.
Implementation:
- HIR lowering detects Array_<T> types in skLet statements
- Generates Array_Free_T generic instance if needed
- Builds synthetic defer node: defer Array_Free_T(&var)
- Wraps let+defer in hBlock for proper statement chaining
Also adds checkedFunc flag to HirFunc and CEmitter for future use.
- Fix nested Lcx_GenerateStructInstance overwriting parent slot by
incrementing structCount BEFORE field processing
- Fix Lcx_LowerModule to skip generic structs from hm.structs (was missing
continue due to bootstrap compiler codegen limitation)
- Fix C backend to forward-declare ALL structs at top, removing second
generic-only forward declaration section that came too late
- Add empty-name guard in CBE_EmitStructDef
- Import system: parser supports ::* glob imports, sema two-pass resolution
- Remove DEBUG prints from c_backend.bux, hir_lower.bux, lexer.bux, parser.bux
- Remove HACK for stray } in parserParseFuncDecl (no longer needed after
Decl refactor in 4a86009)
- Clean selfhost check/build output
- Replace Decl's 256 inline struct fields with dynamic fields: *StructField
array to avoid parser field limit truncation and name shifts.
- Update parser.bux and hir_lower.bux to use decl.fields[i].
- Fix uninitialized Symbol.refType in three stack-allocated Symbol sites:
loopSym (for-loop iterator), vSym (enum variants), and HIR param sym.
Garbage refType values (e.g. 0xFF) were leaking into scope tables,
later copied to expr->refType, causing SIGSEGV in Lcx_LowerExpr.
- Add tekFunc AST node and TypeExprList linked list for params
- Parse func(T, U) -> R syntax in parser.bux
- Resolve tekFunc to tyFunc in sema.bux
- Track original TypeExpr via Symbol.refType for params/lets/consts/funcs
- Build C function-pointer type names in hir_lower.bux (Ret (*)(Params))
- Lower indirect calls through function-typed values as hCallIndirect
- Add CBE_CParamDecl helper in c_backend.bux to embed name inside (*)
- Emit hCallIndirect and function-pointer variable declarations
- _test_funcptr now builds and runs with selfhost buxc2
- Add statement for function-level deferred execution
- Deferred expressions run in LIFO order on function exit (return or implicit)
- Bootstrap: desugar defers in hir_lower.nim (inject before return + end of func)
- Selfhost: emit defers in c_backend.bux via CEmitter defer stack
- Both: add tkDefer token, skDefer AST node, hDefer HIR node
- Parser, lexer, sema, token files updated in both bootstrap/ and src/
Backtick strings were emitted directly into C code without
stripping the backticks or escaping the content, causing C syntax errors.
Fix: detect backtick-wrapped literals in CBE_EmitExpr, strip
the backticks, escape inner content, and wrap in double quotes.
Simple enums were emitted as plain C enums, but the rest of the codegen
(and source code) expected them to have a .tag field like algebraic enums.
This caused C compilation errors:
- 'request for member tag in something not a structure or union'
- 'field name not in record or union initializer'
Fix: always emit the _Tag typedef + struct wrapper for every enum.
For simple enums, the struct only contains the tag (no _Data union).
For algebraic enums, keep the existing _Data union + struct behavior.
This matches the bootstrap compiler's enum codegen.
- ast.bux: Decl expanded with field0..field255, variant0..7, param0..8
- parser.bux: add parserParseUnary for correct unary precedence; handle tkDiscard statements; allow var without initializer (matching bootstrap); add diagCount bounds check in parserEmitDiag
- hir.bux: HirParam changed to pointers
- hir_lower.bux: full field chains for struct lowering
- c_backend.bux: hardened -> vs . field access; null checks in CBE_GetExprTypeName
- cli.bux: add -lcrypto to linker
