From 77c6a98cac3b0b9e98d540802e175e1381427be5 Mon Sep 17 00:00:00 2001 From: Flavio Soibelmann Glock Date: Wed, 18 Feb 2026 18:57:46 +0100 Subject: [PATCH 1/7] feat: Runtime and JVM compiler improvements for context and regex handling This commit consolidates runtime and JVM compiler enhancements: Features: - Add escapeInvalidQuantifierBraces function for Perl regex compatibility (currently disabled due to test regressions - needs more work) - Add DEBUG_REGEX environment variable support for regex debugging Fixes: - Preserve RUNTIME context for RHS of logical operators in JVM compiler - Evaluate LHS of logical operators in SCALAR context (for boolean test) - Add debug logging to RuntimeRegex.compile() and matchRegexDirect() Implementation Details: - EmitLogicalOperator: Changed context handling for logical operators - LHS evaluated in SCALAR context for boolean test - RHS preserves RUNTIME context when in RUNTIME mode - Prevents context loss at subroutine exits - RegexPreprocessor: Added escapeInvalidQuantifierBraces() - Handles Perl-style quantifier braces like {1}, {,3}, {2,5} - Escapes invalid braces that would cause Java Pattern.compile() errors - Currently disabled (line 82-84) due to edge case regressions - Function ready for future refinement and re-enabling - RuntimeRegex: Added DEBUG_REGEX support - Set DEBUG_REGEX=1 environment variable to enable regex debug output - Logs pattern compilation, cache hits/misses, and matching operations - Helps diagnose regex preprocessing and matching issues Files Modified: - EmitLogicalOperator.java: +17/-12 lines - RegexPreprocessor.java: +212/-0 lines - RegexPreprocessorHelper.java: +123/-71 lines (refactored) - RuntimeRegex.java: +41/-13 lines Test Results (vs master): - re/regexp.t: 1788/2210 (+2) - re/pat.t: 896/1296 (+1) - re/pat_rt_report.t: 2384/2514 (+3) - re/reg_mesg.t: 1642/2479 (no change) - Net: +6 improvements, 0 regressions Co-Authored-By: Claude Opus 4.6 --- .../codegen/EmitLogicalOperator.java | 17 +- .../perlonjava/regex/RegexPreprocessor.java | 212 ++++++++++++++++++ .../regex/RegexPreprocessorHelper.java | 123 +++++----- .../org/perlonjava/regex/RuntimeRegex.java | 41 +++- 4 files changed, 323 insertions(+), 70 deletions(-) diff --git a/src/main/java/org/perlonjava/codegen/EmitLogicalOperator.java b/src/main/java/org/perlonjava/codegen/EmitLogicalOperator.java index ed6bd473c..b80192f60 100644 --- a/src/main/java/org/perlonjava/codegen/EmitLogicalOperator.java +++ b/src/main/java/org/perlonjava/codegen/EmitLogicalOperator.java @@ -311,15 +311,10 @@ private static void emitLogicalOperatorSimple(EmitterVisitor emitterVisitor, Bin rewritten = true; } - // For RUNTIME context, preserve it; otherwise use SCALAR for boolean evaluation - int operandContext = emitterVisitor.ctx.contextType == RuntimeContextType.RUNTIME - ?

In Perl, the default bitwise operators perform numeric operations, not string operations. This bug caused eval STRING expressions like 'eval "83 | 120"' to return 930 (string bitwise OR result) instead of 123 (numeric bitwise OR result). Fixed: - & now emits BITWISE_AND_BINARY (was STRING_BITWISE_AND) - | now emits BITWISE_OR_BINARY (was STRING_BITWISE_OR) - ^ now emits BITWISE_XOR_BINARY (was STRING_BITWISE_XOR) The string bitwise operators (&., |., ^.) continue to emit STRING_BITWISE_* opcodes correctly. Impact: Fixes interpreter parity for bitwise operations in eval STRING context.

Key Features: - Automatically reads LASTOP from Opcodes.java to determine next opcode - Skips existing opcodes to avoid duplicates - Generates handler classes with efficient zero-overhead dispatch pattern - Automatically updates Opcodes.java, BytecodeInterpreter.java, and InterpretedCode.java at marker locations - Uses -> syntax for clean, modern Java code Generated Handlers: - ScalarUnaryOpcodeHandler: 31 operators (chr, ord, abs, sin, cos, lc, uc, etc.) - ScalarBinaryOpcodeHandler: 12 operators (atan2, eq, ne, lt, le, gt, ge, cmp, binary&, binary|, binary^, x) Opcodes Generated: - Reserved range: 221-263 (43 opcodes) - Next available: 264 Markers Added: - // GENERATED_OPCODES_START/END in Opcodes.java - // GENERATED_HANDLERS_START/END in BytecodeInterpreter.java - // GENERATED_DISASM_START/END in InterpretedCode.java Implementation: - Added LASTOP constant to track manually-assigned opcodes - Tool excludes generated sections when reading existing opcodes - Skips operators with complex signatures (varargs, etc.) - Skips operators that already have opcodes (rand, length, rindex, index, require, isa, bless, ref, join, prototype, getc) Future Work: - Add BytecodeCompiler.java generation for emit cases - Add more operator types (list, array, hash operations) Co-Authored-By: Claude Opus 4.6 --- dev/prompts/generated_opcodes_report.txt | 257 +++++++++ dev/prompts/opcode_conflicts.md | 61 ++ dev/prompts/operator_generation_summary.md | 35 ++ dev/tools/generate_opcode_handlers.pl | 544 ++++++++++++++++++ .../interpreter/BytecodeInterpreter.java | 60 ++ .../interpreter/InterpretedCode.java | 61 ++ .../org/perlonjava/interpreter/Opcodes.java | 63 +- .../ScalarBinaryOpcodeHandler.java | 74 +++ .../interpreter/ScalarUnaryOpcodeHandler.java | 115 ++++ 9 files changed, 1268 insertions(+), 2 deletions(-) create mode 100644 dev/prompts/generated_opcodes_report.txt create mode 100644 dev/prompts/opcode_conflicts.md create mode 100644 dev/prompts/operator_generation_summary.md create mode 100755 dev/tools/generate_opcode_handlers.pl create mode 100644 src/main/java/org/perlonjava/interpreter/ScalarBinaryOpcodeHandler.java create mode 100644 src/main/java/org/perlonjava/interpreter/ScalarUnaryOpcodeHandler.java diff --git a/dev/prompts/generated_opcodes_report.txt b/dev/prompts/generated_opcodes_report.txt new file mode 100644 index 000000000..61deb27dd --- /dev/null +++ b/dev/prompts/generated_opcodes_report.txt @@ -0,0 +1,257 @@ +Reading existing opcodes... + Found 221 existing opcodes + +Parsing OperatorHandler.java... + Skipping rand (RAND) - already exists as opcode 91 + Skipping length (LENGTH) - already exists as opcode 30 + Skipping rindex (RINDEX) - already exists as opcode 173 + Skipping index (INDEX) - already exists as opcode 172 + Skipping require (REQUIRE) - already exists as opcode 170 + Skipping isa (ISA) - already exists as opcode 105 + Skipping bless (BLESS) - already exists as opcode 104 + Skipping ref (REF) - already exists as opcode 103 + Skipping join (JOIN) - already exists as opcode 88 + Skipping prototype (PROTOTYPE) - already exists as opcode 158 + +Parsed operators by signature: + scalar_binary : 12 operators + scalar_unary : 32 operators + +Generating ScalarBinaryOpcodeHandler with 12 operators... + Generated: src/main/java/org/perlonjava/interpreter/ScalarBinaryOpcodeHandler.java +Generating ScalarUnaryOpcodeHandler with 32 operators... + Generated: src/main/java/org/perlonjava/interpreter/ScalarUnaryOpcodeHandler.java + +====================================================================== +UPDATE INSTRUCTIONS +====================================================================== + +1.

charset=UTF-8 Content-Transfer-Encoding: 8bit Added manual emit cases for key unary operators (chr, ord, hex, oct, abs, int, uc, lc) in BytecodeCompiler.java to enable interpreter execution. Updated SKILL.md with comprehensive code generator documentation: - Quick start guide - Eligibility criteria for operators - LASTOP management critical for opcode numbering - Common gotchas and solutions - Testing procedures - Manual implementation guidance All 17 test cases now pass with interpreter: ✓ chr, ord, abs, int, uc, lc, hex, oct (unary) ✓ eq, ne, cmp, lt, gt, x (binary) ✓ Bitwise OR, AND, XOR Next: Enhance tool to auto-generate BytecodeCompiler emit cases to reduce code repetition.

Now assigns opcodes contiguously grouped by signature type: - Binary operators: LASTOP+1 through LASTOP+12 (12 contiguous) - Unary operators: LASTOP+13 through LASTOP+43 (31 contiguous) This ensures JVM uses tableswitch (O(1)) instead of lookupswitch (O(log n)) for optimal interpreter performance. Verified with javap showing "tableswitch { // 0 to 263" covering all opcodes. All 17 test cases pass (chr, ord, abs, int, uc, lc, hex, oct, eq, ne, cmp, lt, gt, x, bitwise |, &, ^).
