Fix multiple bugs found via the array_list.zig corpus test: - Fix anytype param ref/index double-conversion (addStrTok returns a ref, don't add ZIR_REF_START_INDEX again) - Implement is_generic param tracking via is_used_or_discarded pointer in ScopeLocalVal - Fix globalVarDecl declaration src_line: use type_gz.decl_line instead of ag->source_line (which was advanced by init expression) - Fix cppcheck warning: remove redundant (0u << 2) in bitmask - Implement fetchRemoveRefEntries and ret_param_refs in addFunc - Add func_fancy case to buildHashSkipMask in test - Fix valgrind: zero elem_val_imm padding, skip addNodeExtended undefined small field, handle more padding-sensitive tags Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
About
zig0 aspires to be an interpreter of zig 0.15.2 written in C.
This is written with help from LLM:
- Lexer:
- Datastructures 100% human.
- Helper functions 100% human.
- Lexing functions 50/50 human/bot.
- Parser:
- Datastructures 100% human.
- Helper functions 50/50.
- Parser functions 5/95 human/bot.
- AstGen: TBD.
Testing
Quick test:
zig build fmt-zig0 test-zig0
Full test and static analysis with all supported compilers and valgrind (run before commit, takes a while):
zig build all-zig0 -Dvalgrind
Debugging tips
Test runs infinitely? Build the test program executable:
$ zig build test-zig0 -Dzig0-no-exec
And then run it, capturing the stack trace:
gdb -batch \
-ex "python import threading; threading.Timer(1.0, lambda: gdb.post_event(lambda: gdb.execute('interrupt'))).start()" \
-ex run \
-ex "bt full" \
-ex quit \
zig-out/bin/test
You are welcome to replace -ex "bt full" with anything other of interest.
