ensured thorough state cleanup in llvm_gen_be_terminate. - Verifier Integration: Added function verification pass via llvm::verifyFunction with source position mapping on diagnostic failure. - Exception Handling & RTTI: Lowered typeinfo references using EDG mangled names (__cxa_throw typeinfo/dtor args) and added catch clause dispatch matching via llvm.eh.typeid.for. - Inline Assembly: Supported multiple outputs via struct returns, indirect memory operand constraints (*), and value extraction to lvalue destinations. - Type System & Opaque Pointers: Streamlined GEP and pointer bitcasts for opaque pointer support; added explicit float/complex kind mappings (bfloat16, fp16, fp80, fp128, etc.). - Testing & Coverage: Added multi-output inline asm test, lit test cases for for-loops and opaque pointers, orchestrator/verifier test targets, and coverage validation scripts. --- src/llvm_gen_be.cpp | 40 +++++- src/llvm_gen_be_const.cpp | 10 +- src/llvm_gen_be_decl.cpp | 13 +- src/llvm_gen_be_expr.cpp | 79 +++++++++--- src/llvm_gen_be_internal.h | 2 + src/llvm_gen_be_stmt.cpp | 154 +++++++++-------------- src/llvm_gen_be_type.cpp | 103 +++++++++++---- tests/CMakeLists.txt | 6 + tests/lit/llvm/opaque_pointers.c | 11 ++ tests/lit/llvm/stmt_for.c | 12 ++ tests/llvm_ir_backend_tests/asm_test.cpp | 22 ++++ tests/run_coverage.sh | 9 ++ tests/test_llvm_coverage.sh | 33 +++++ tests/test_llvm_orchestrator.cpp | 18 +++ tests/test_llvm_verifier.cpp | 6 + 15 files changed, 377 insertions(+), 141 deletions(-) create mode 100644 tests/lit/llvm/opaque_pointers.c create mode 100644 tests/lit/llvm/stmt_for.c create mode 100755 tests/test_llvm_coverage.sh create mode 100644 tests/test_llvm_orchestrator.cpp create mode 100644 tests/test_llvm_verifier.cpp diff --git a/src/llvm_gen_be.cpp b/src/llvm_gen_be.cpp index aeb0865c60..7747f74d94 100644 --- a/src/llvm_gen_be.cpp +++ b/src/llvm_gen_be.cpp @@ -87,7 +87,7 @@ static void emit_global_ctors_and_dtors() { std::vector dtors;

+1300 Subject: [PATCH 6/8] LLVM IR backend: implement target ABIs, DWARF debug info, code emission, and pass pipeline Implement target calling convention ABIs (AAPCS64, SysV x86-64, Win64), DWARF debug metadata emission, machine code/assembly generation, optimization pipelines, and centralized error handling with test coverage: - Target Calling Conventions: Implemented ABI argument and return value classification for SysV x86-64, AAPCS64, and Win64 calling conventions, supporting direct, indirect, sret, coercion, and register attributes. - DWARF Debug Information: Added DIBuilder lifecycle management, compile unit setup, subprogram declarations, lexical block scopes, debug locations on instructions, and type metadata for primitives, pointers, and variables. - Code Generation & Emission: Integrated LLVM TargetMachine code generation to emit object files (.o) and assembly (.s); hooked into cpfe CLI flags (--gen_llvm_file_name, --llvm_opt_level, etc.). - Optimization Pipeline: Integrated LLVM new PassManager supporting optimization levels O0 through O3, Os, Oz, along with loop and SLP vectorization passes. - Error Handling & Modularization: Added centralized error subsystem with structured error contexts (llvm_gen_be_error_t); decoupled internal declarations into dedicated headers (llvm_gen_be_type.h, llvm_gen_be_expr.h, llvm_gen_be_const.h). - Test Infrastructure: Added unit tests for ABIs, DWARF metadata, pass pipelines, fault injection, and codegen, along with lit tests, GCC torture runner, and STL header compilation validation. ---
