From 674ec84f172c2fbed6d8a9614289c73841130e89 Mon Sep 17 00:00:00 2001 From: Matt Godbolt Date: Mon, 9 Jun 2025 11:11:52 -0500 Subject: [PATCH 1/3] Fix statically linked library functions being filtered out MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary - Fixes issue where statically linked library functions like `__divdc3` were incorrectly filtered out even when directly called by user code - Implements a smart two-pass solution that keeps referenced functions while still filtering out unused library code ## Changes - **New method**: `collectReferencedFunctions()` scans assembly to identify function calls from user code - **Enhanced filtering**: Functions are now kept if they're either user functions OR referenced by user functions - **Comprehensive test case**: Added `ce-bug-1648.asm` test demonstrating `__divdc3` usage and proper filtering ## Root Cause The `binaryIgnoreFunction` regex filtered out all functions starting with `__`, including `__divdc3`, even when they were statically linked and called from user code. This created a poor user experience where important library function implementations were hidden. ## Solution Two-pass approach: 1. **Pass 1**: Scan all assembly lines to collect functions referenced from user code 2. **Pass 2**: Apply enhanced filtering logic that keeps both user functions and referenced library functions ## Impact - **Positive**: Users can now see implementations of library functions they're actually calling - **Minimal**: Unreferenced library functions are still filtered out to avoid output bloat - **Backward compatible**: No change in behavior for existing use cases Based on compiler-explorer/compiler-explorer#7776 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- CLAUDE.md | 100 ++++++++++++++ ...text_filter_tests.ce-bug-3963.approved.txt | 2 +- ...er_tests.filter_example_intel.approved.txt | 128 ++++++++++++++++++ resources/ce-bug-1648.asm | 32 +++++ src/objdump/parser.cpp | 73 +++++++++- src/objdump/parser.hpp | 3 + 6 files changed, 335 insertions(+), 3 deletions(-) create mode 100644 CLAUDE.md create mode 100644 resources/ce-bug-1648.asm diff --git a/CLAUDE.md b/CLAUDE.md new file mode 100644 index 0000000..c6c97c6 --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1,100 @@ +# CLAUDE.md + +This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository. + +## Project Overview + +asm-parser is a C++ tool that categorizes and filters assembly code for Compiler Explorer.
