- Fix lirValToC crash on lvkInt in hStore raw C emission
- Add hAlloca handling to lowerExpr (returns &name, avoids unhandled fallback)
- Fix nested comment syntax in unhandled expr fallback
- Rewrite buildLval to handle hIndexPtr and nested hFieldPtr/hArrowField
so assignments like arr[i].field = val emit direct C lvalues
- Make &&/|| temporaries unique (__and_tmp_N/__or_tmp_N) to avoid
duplicate declarations in the same function
- Selfhost null-deref fix in sema.bux (unchained nested conditions)
The old findGenericCalls second-pass only looked in non-generic functions
and generated unresolved instances like Array_Get_T when generic funcs
called other generic funcs. Removed it entirely.
lowerExpr for ekCall now invokes generateMethodInstance directly for
both explicit (ekGenericCall) and inferred generic calls. This ensures
concrete instantiations are generated on-demand with correct typeSubst.
Also added guard in resolveTypeExpr/substituteType to skip emitting C
struct definitions for unresolved type parameters (e.g. Array<T> inside
a generic function body before monomorphization).
feat(std): add Std::Iter module
- Array_Iter, Iter_Next, Iter_HasNext, Iter_Peek, Iter_Reset
- Iter_Pos, Iter_Len, Iter_Count, Iter_Skip, Iter_Take
docs: document Std::Iter in Stdlib.md
examples: add iter.bux example
tests: add _test_array regression test
- Added exprSpawnAsync flag to AST ekSpawn
- Sema checks if callee is async and sets the flag
- HIR hSpawn carries spawnAsync flag
- C backend uses bux_task_spawn for non-async (OS threads) and bux_async_spawn for async (coroutines)
- Added concurrency example to test suite
Self-hosted compiler (buxc2):
- Add async/await/spawn tokens, parsing, HIR, lowering, C emission
- Fix pointer type emission (*T -> T*) in C backend
- Fix sizeof(Type) parsing with parentheses
- Fix import ::{...} infinite loop guard
- Fix int64 emission by avoiding else-if chain workaround
- Add debug-free cli and hir_lower
Bootstrap compiler (Nim):
- Fix critical else-if lowering bug in hir_lower.nim:
when both elseIfs and else block exist, elseIfs were dropped
causing all else-if chains to collapse to if+else only
Runtime:
- Fix bux_async_await memory corruption (don't free in run)
- Add bux_remove_from_ready for safe cleanup
- Fix forward declaration and deduplicate bux_now_ms
Docs & examples:
- Update async.bux example with proper int64 params
- Update README, LanguageRef, Stdlib, PLAN for async features
- Mark Phase 7.10 bootstrap loop as completed
All 27 examples pass. buxc2 check/build work on all examples.
- Add generic struct instantiation (Box<int>, Pair<T,U>) in HIR lowering
- Fix tkUnknown/tkNamed/tkTypeParam ambiguity in sema.nim (qualify with TypeKind)
- Add generics_struct example
- Update Makefile with new example
Add standard library modules:
- Std::String: strlen, strcmp, concat, copy, starts_with wrappers
- Std::Map: linear-probing hash map with String keys, int values
Add error handling:
- Result and Option algebraic enum examples
- ? try operator for automatic error propagation in HIR lowering
Compiler bugfixes:
- Fix sizeof() for user-defined structs (new hSizeOf HIR node)
- Fix HIR type lowering for char8, bool8, int8, uint8, etc.
- Fix let statement lowering for pointer types (*char8 → int* bug)
- Fix PrintInt ABI mismatch (int64_t → int in io.c)
- Fix Makefile test bug (_test_tmp_pkg already exists)
Documentation:
- Rewrite README.md with features, examples, project structure
- Add docs/LanguageRef.md — complete language reference
- Add docs/Stdlib.md — standard library documentation
- Add docs/BuildAndTest.md — build and test guide
New examples: strings, map, result_option, try_operator (13 total)
- C backend: strip c8/c16/c32 string prefixes in emitted C
- C backend: resolve imports to fully-qualified names (Std_Io_PrintLine)
- Parser: fix infinite loop on < in comparisons vs generic calls
- Parser: fix enum patterns without parens (Option::None)
- Parser: fix match expressions inside blocks
- Sema: extract pattern bindings for match arms
- HIR: lower match expressions to if-else chains with enum tag checks
- HIR/C backend: support block expressions as function return values
- Makefile: add integration tests for all 9 examples
- Add pattern_matching.bux example
