- blockExpr: call rvalue on void result for unlabeled blocks, matching
upstream AstGen.zig:2431. This was causing a missing STORE_NODE when
empty blocks like {} were used as struct field values with pointer RL.
- identifierExpr: call rvalueNoCoercePreRef after LOAD in local_ptr case,
matching upstream AstGen.zig:8453-8454.
- Implement AST_NODE_ARRAY_MULT (** operator) with ArrayMul payload,
matching upstream AstGen.zig:774-785.
- Enable parser_test.zig and astgen_test.zig corpus tests.
- Enable combined corpus test (all 5 files pass).

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.
