Handle anonymous struct init (.{.a = b}) when the result location has
a type (RL_TY/RL_COERCED_TY). Emit validate_struct_init_result_ty and
struct_init_field_type instructions, matching upstream AstGen.zig:
1706-1731 and structInitExprTyped.
Also add validate_struct_init_result_ty to test comparison functions
and fix char literal escape sequences.
build.zig corpus: improved from 25 to 3 inst diff (remaining:
as_node coercion in rvalue).

About
zig0 aspires to be an interpreter of zig 0.15.1 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 test
Full test and static analysis with all supported compilers and valgrind (run before commit, takes a while):
zig build -Dvalgrind
Debugging tips
Test runs infinitely? Build the test program executable:
$ zig build test -Dno-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.
