Key changes: Syntax: catch clauses now require an explicit type argument (e.g., (catch cpp/jank.runtime.object_ref e ...)). Parser: Updated parse_try to handle multiple catch clauses with their corresponding types. Codegen: Extended LLVM IR generation to support multiple catch blocks. Tests: Updated existing tests to use the new explicit catch syntax and added new tests for multiple catches, nested try-catch-finally blocks, etc.. --- .../include/cpp/jank/analyze/expr/try.hpp | 4 +- .../cpp/jank/detail/to_runtime_data.hpp | 17 +- .../src/cpp/jank/analyze/cpp_util.cpp | 13 + .../src/cpp/jank/analyze/expr/try.cpp | 16 +- .../src/cpp/jank/analyze/processor.cpp | 87 +- .../src/cpp/jank/codegen/llvm_processor.cpp | 847 +++++++++++------- .../src/cpp/jank/codegen/processor.cpp | 6 +- compiler+runtime/src/cpp/jank/evaluate.cpp | 30 +- compiler+runtime/src/jank/clojure/core.jank | 2 +- .../jank/cpp/try/pass-catch-cpp-char.jank | 13 + .../jank/cpp/try/pass-catch-cpp-double.jank | 13 + .../jank/cpp/try/pass-catch-cpp-float.jank | 13 + .../test/jank/cpp/try/pass-catch-cpp-int.jank | 13 + .../jank/cpp/try/pass-catch-cpp-pointer.jank | 16 + .../cpp/try/pass-catch-cpp-std-bad-cast.jank | 17 + .../cpp/try/pass-catch-cpp-std-exception.jank | 11 + .../pass-catch-cpp-std-invalid-argument.jank | 13 + .../try/pass-catch-cpp-std-logic-error.jank | 13 + .../try/pass-catch-cpp-std-out-of-range.jank | 13 + .../try/pass-catch-cpp-std-runtime-error.jank | 13 + .../cpp/try/pass-catch-cpp-unsigned-int.jank | 14 + .../try/pass-multiple-catch-cpp-classes.jank | 53 ++ .../pass-multiple-catch-cpp-with-finally.jank | 37 + .../try/pass-multiple-catch-mixed-types.jank | 32 + .../cpp/try/pass-rethrow-cpp-exception.jank | 16 + .../pass-uncaught-cpp-exception-finally.jank | 17 + .../form/try/fail-catch-after-finally.jank | 2 +- .../jank/form/try/fail-multiple-catch.jank | 5 -

Although jank builds cleanly on vanilla macOS, these nix-darwin settings interfere with the build process in two ways: 1. AOT Compilation: Platform-specific linker library requirements need proper handling. On macOS, Clang uses libc++ by default and doesn't require explicit -lstdc++ linking, while Linux requires it. 2. JIT Compilation: Clang extracts system include paths containing absolute SDK paths (e.g., /Applications/Xcode.app/.../MacOSX.sdk/usr/include or /Library/Developer/CommandLineTools/SDKs/MacOSX*.sdk/usr/include). These paths get embedded in JANK_JIT_FLAGS and cause header ordering issues at runtime when jank performs JIT compilation. ## Solution ### Part 1: Platform-aware AOT compilation with runtime checks - Moved -lstdc++ linking decision from build-time CMake to runtime C++ code - Use if constexpr(jtl::current_platform != jtl::platform::macos_like) checks - This approach is simpler and more maintainable than CMake configuration files - On macOS: Exclude -lstdc++ (uses libc++ implicitly via Clang) - On Linux: Include -lstdc++ (requires explicit linking) - Removed -L/opt/homebrew/opt/llvm/lib/unwind which is not needed on macOS ### Part 2: Filter SDK paths from JIT compilation flags - Create a filtered version of clang_system_include_flags for JIT compilation - Exclude paths matching /SDKs/ from JIT flags while preserving them for the build itself This separation ensures: - Build-time includes: Use unfiltered paths (need SDK headers for compilation) - JIT runtime flags: Use filtered paths (SDK comes from -isysroot at JIT time) The filtering prevents baking absolute SDK paths into the binary while still allowing the build itself to find necessary system headers. At JIT time, the correct SDK is obtained from -isysroot dynamically rather than hardcoded build-time paths, making jank portable across different macOS/Nix configurations. ## Verification - Builds successfully with SDKROOT set (nix-darwin environment) - Builds successfully on vanilla macOS - JIT compilation works correctly with filtered flags - All check-health tests pass - AOT compilation generates correct platform-specific binaries --- compiler+runtime/CMakeLists.txt | 18 ++++++++++++++++-- .../src/cpp/jank/aot/processor.cpp | 8 +++++++- 2 files changed, 23 insertions(+), 3 deletions(-) diff --git a/compiler+runtime/CMakeLists.txt b/compiler+runtime/CMakeLists.txt index 6654d5240..9fcbcb0d2 100644 --- a/compiler+runtime/CMakeLists.txt +++ b/compiler+runtime/CMakeLists.txt @@ -113,7 +113,7 @@ set( ) if (NOT jank_local_clang) - list(APPEND jank_linker_flags -L/opt/homebrew/opt/llvm/lib -L/opt/homebrew/opt/llvm/lib/c++ -L/opt/homebrew/opt/llvm/lib/unwind) + list(APPEND jank_linker_flags -L/opt/homebrew/opt/llvm/lib -L/opt/homebrew/opt/llvm/lib/c++) endif () # If the user opts into a specific build type, we will provide sane defaults.

Added automatic promotion of C++ class/struct catch types to lvalue references - Prevents object slicing when catching derived classes by base type - Preserves polymorphic behavior (virtual methods work correctly) - Exception: jank::runtime types (like object_ref) remain by-value (needs to figure out why) **Duplicate Catch Detection (lines 2785-2796)** - Added compile-time validation to detect duplicate catch clauses **Fixed Pointer Exception Handling (lines 1797-1826)** - Corrected exception value extraction for pointer types - Pointer exceptions: Use caught_ptr directly (it IS the pointer value) - Non-pointer exceptions: Dereference caught_ptr to get the value - Fixes crashes when catching void*, int*, and other pointer types - Added support for reference types and class/struct types **Enhanced Load Detection (line 543)** - Extended auto-load logic to handle pointer and reference types - Ensures proper value extraction from alloca instructions --- .../src/cpp/jank/analyze/cpp_util.cpp | 6 +- .../src/cpp/jank/analyze/processor.cpp | 74 ++++++++++++++----- .../src/cpp/jank/codegen/llvm_processor.cpp | 44 +++++++---- .../jank/cpp/try/pass-catch-cpp-char.jank | 13 ---- .../jank/cpp/try/pass-catch-cpp-double.jank | 13 ---- .../jank/cpp/try/pass-catch-cpp-float.jank | 13 ---- .../test/jank/cpp/try/pass-catch-cpp-int.jank | 13 ---- .../jank/cpp/try/pass-catch-cpp-pointer.jank | 16 ---- .../cpp/try/pass-catch-cpp-std-bad-cast.jank | 17 ----- .../cpp/try/pass-catch-cpp-std-exception.jank | 11 --- .../pass-catch-cpp-std-invalid-argument.jank | 13 ---- .../try/pass-catch-cpp-std-logic-error.jank | 13 ---- .../try/pass-catch-cpp-std-out-of-range.jank | 13 ---- .../try/pass-catch-cpp-std-runtime-error.jank | 14 ---- .../cpp/try/pass-catch-cpp-unsigned-int.jank | 14 ---- .../pass-local-reference-to-cpp-value.jank | 4 -
