(a&b)+(a|b) = a+b, documented honestly: falls to the same symbolic
evaluator as xor/add/shift (every sub-expression is a foldable
LDC,LDC,BINOP triple), but defeats a pattern matcher hardcoded to one
opcode ("ldc,ldc,ixor = split constant"). Added to ConstantsConfig
default schemes.
Tests: mba_form_uses_and_or_add_not_a_single_binop, round-trip coverage
in int_forms_round_trip/long_forms_keep_shape.
DebugConfig gains fake_line_numbers (deterministic upward walk
replacing LineNumberTable rows when stripping is off; strip wins)
and strip_source_file (drops SourceFile entirely, beating spoof).
Debug tests moved to passes/tests/debug_info.rs with new cases
for both flags and their precedence.
NoisePass now builds branching helper methods (counted int loop,
random arithmetic, even/odd merge, non-throwing ops only) whose
results the entry sums into a private static field, instead of an
empty run()V. Names come from the same NameGenerator styles as
real code and live in a random real package (no more shadow/decoy
uniformity for grep to catch); every generated method gets fresh
StackMapTable frames. weave_first_reachable takes (class, entry)
pairs. New NoiseConfig.junk_methods_per_class (default 3).
Tests assert invariants (unique valid identifiers, calls, field
store, determinism) plus real-JVM verification of junk classes;
paranoid+junk_ratio=1 smoke on lorep: 18 junk classes, all load.
Proven by paranoid runs over lorep (17 classes, fully green),
LoVisual (4081 classes) and oc2r (1278 classes) with per-class
java -Xverify:all, each fix first reproduced as a red test:
- merge: Top absorbs instead of Top-wins (javac declares Top for
slots unwritten on some inflow; precise types reject those edges).
Regression: loop_head_keeps_top_for_loop_local.
- emit: collapse [Long|Double, Top] pairs on operand stacks
(javac writes one entry; the pair is rejected). Regression:
wide_stack_join_emits_single_entries.
- xfer ArrayLoad: push the wide pair, fixing lcmp underflow.
Regression: array_load_wide_pushes_pair.
- xfer <init>: convert only the receiver's own allocation site
instead of every Uninitialized (nested construction clobbered
the outer object). Regression: nested_construction_keeps_outer.
- xfer ANewArray: array operands gain one dimension ([B] -> [[B)
instead of an illegal L-wrap ([L[B;). Covered by the same test.
- jar load: duplicate class names (multi-release module-info
twins) keep the first occurrence instead of crashing save.
Test: duplicate_class_names_keep_first.
- strings/constants: skip methods past MAX_METHOD_INSNS (8000)
so giants cannot overflow the 64KB writer ceiling. Tests:
oversized_methods_are_skipped in both passes.
- merge errors now name both types being merged.
Also: em-dash removed repo-wide (724 spots, rule added to
todo.md), allow-lints only in tests (scratch example deleted),
code comments migrated to English in every file this change
touches.
Gate ignores blank and full-line comment lines so the 250-line limit
measures code bulk, not documentation weight; docs/README.md synced.
Translate code comments to English in classfile, core config, namegen,
rename assign, constants forms. Expand Plausible word bank with
client-ecosystem terms (Module, Setting, Mixin, ...). cargo fmt clean,
check.sh green.
ristretto's ConstantPool never deduplicates: every add_* pushes a new entry.
HotSpot matches each LocalVariableTypeTable entry to a LocalVariableTable
entry by raw name_index, so when a name (e.g. a local's) was interned twice
the two tables got different indices and the class failed to load:
'ClassFormatError: LVTT entry ... does not match any LVT entry'.
The writer now memoizes every pool builder by its semantic key and rebuilds
composite constants (Class/NameAndType/Fieldref/Methodref/MethodHandle/
Dynamic) from our own utf8/class primitives so ristretto never mints a
shadow Utf8. This also shrinks the pool (no more ldc -> ldc_w widening that
changed code length on a pure round-trip).
Split pool.rs into a pool/ module (refs in pool/refs.rs) to respect the
file-size gate. Regression test: tests/pool asserts the written pool has no
duplicate CONSTANT_Utf8. Verified: pure parse->write of the neoforge jar
(92 classes) now loads under java -Xverify:all with 0 errors.
