Additionally: - Support GCC backend CLI optimization and debug flags in cmd_line.[ch] (-O0..-O3, -Os, -Ofast, -g, -fPIC, -fPIE, dump flags). - Update src/CMakeLists.txt for the new modular sources and coverage flags. - Expand tests/gcc_be/ suite and modernize coverage verification script to inspect all gcc_gen_be_*.c compilation units. --- src/CMakeLists.txt | 23 +- src/cfe.c | 4 +- src/cmd_line.c | 30 + src/cmd_line.h | 32 +- src/gcc_gen_be.c | 1418 ----------------------------- src/gcc_gen_be.h | 25 -

Marks <807580+SamuelMarks@users.noreply.github.com> Date: Sun, 11 Oct 2026 20:15:53 +1300 Subject: [PATCH 5/7] Implement ABI, builtins, RTTI, EH, and dtor subsystems in GCC backend Expand the native libgccjit backend (gcc_gen_be) with comprehensive language feature lowering, runtime support, lexical scoping, and subsystem test coverage: - ABI, Calling Conventions, and Attributes (src/gcc_gen_be_abi.[ch]): - Implement gcc_gen_be_apply_function_attributes, gcc_gen_be_apply_struct_attributes, and gcc_gen_be_apply_variable_attributes for packing, alignment, TLS, and linkage. - Builtins and Intrinsics (src/gcc_gen_be_builtin.[ch]): - Add gcc_gen_be_lower_builtin_call using libgccjit builtin function lookup. - RTTI, VTables, and Thunks (src/gcc_gen_be_rtti.[ch]): - Add vtable and VTT emission (gcc_gen_be_emit_vtable, gcc_gen_be_emit_vtt). - Generate virtual method dispatch thunks (gcc_gen_be_emit_thunk). - Implement dynamic_cast and typeid lowering with type_info descriptor emission. - Exception Handling and RAII Destructors (src/gcc_gen_be_eh.[ch], src/gcc_gen_be_dtor.[ch]): - Declare standard EH symbols (__cxa_throw, etc.) and lower throw expressions. - Implement __cxa_atexit and __cxa_thread_atexit registration for global and TLS destructors. - Lexical Scopes and Control Flow (src/gcc_gen_be_context.[ch], src/gcc_gen_be_stmt.[ch], src/gcc_gen_be_cache.[ch]): - Introduce lexical scope push/pop stacks to support variable shadowing. - Add stack save/restore helpers for VLA allocation. - Expand cache types for local static guard variables and string constants. - Dynamic Symbol Loader (src/gcc_gen_be_lib_loader.[ch]): - Dynamically load modern libgccjit symbols for union constructors, bitcasts, vector rvalues, builtin retrieval, and link sections. - CLI and Driver Integration (src/cmd_line.[ch], src/gcc_gen_be_main.c): - Register --gcc_gen_be and -c command-line options. - Lower function scopes with lexical scope tracking and default terminator emission. - Subsystem Unit Tests and Coverage (tests/gcc_be/, dev_tools/): - Add subsystem test suites for ABI, builtins, debug, dtor, main, RTTI, and statements. - Update CMake targets and end-to-end backend test fixtures. - Add scripts for verifying backend test and documentation coverage. - Remove deprecated dev-init.py. --- dev-init.py | 471

cf7106287bc8ecb1f2b43e39dfc2076bbf5fc879 Mon Sep 17 00:00:00 2001 From: Samuel Marks <807580+SamuelMarks@users.noreply.github.com> Date: Wed, 14 Oct 2026 10:52:56 +1300 Subject: [PATCH 6/7] Implement target ABI classification, CLI driver flags, and DWARF debug in GCC backend Expand the native libgccjit backend (gcc_gen_be) with target-specific ABI parameter and return value classification, comprehensive CLI driver options, multi-TU support, DWARF debug info emission, exception handling routines, and GoogleTest unit suites: - Target ABI Classification (src/gcc_gen_be_abi.[ch]): - Implement System V AMD64 classification (gcc_gen_be_classify_sysv_amd64) with eightbyte decomposition across INTEGER, SSE, X87, and MEMORY classes. - Add AAPCS64 (ARM64) classification (gcc_gen_be_classify_aapcs64) for HFA/HVA. - Add Windows x64 parameter classification (gcc_gen_be_classify_win64). - Add Darwin ARM64 calling conventions and invisible reference / sret detection (gcc_gen_be_is_passed_by_invisible_reference, gcc_gen_be_is_returned_via_sret, gcc_gen_be_classify_darwin_arm64). - CLI Driver and Multi-TU Compilation (src/cfe.c, src/cmd_line.[ch], src/gcc_gen_be_main.[ch]): - Register compilation stage flags (-S, -c) and backend driver switches (--gcc_gen_be). - Add target architecture, tuning, and floating-point flags (-march, -mcpu, -mtune, -mfpu, -mcmodel, -m32, -m64, -ffast-math, -fno-trapping-math, -fassociative-math, -fno-pie, -shared, -static, -L, -l, -fdump-rtl-all). - Implement gcc_gen_be_early_init, gcc_gen_be_apply_command_line_options, gcc_gen_be_compile_multi_tu, and gcc_gen_be_emit_artifact. - Propagate backend initialization and execution status in cfe.c. - Exception Handling and Coroutines (src/gcc_gen_be_eh.[ch], src/gcc_gen_be_stmt.[ch]): - Implement per-function EH lifecycle management (gcc_gen_be_begin_function_eh, gcc_gen_be_end_function_eh). - Add try-catch block lowering (gcc_gen_be_lower_try_block) and function body lowering with exception specification enforcement (gcc_gen_be_lower_routine_body). - Add coroutine frame, ramp, and dispatcher lowering entry points. - Implement stack save and restore helpers for variable-length arrays (VLAs). - Debug Metadata and Error Reporting (src/gcc_gen_be_debug.[ch], src/gcc_gen_be_error.[ch]): - Add DWARF emission for compile units, subprograms, types, variables, and lexical blocks. - Expand gcc_gen_be_error_t enumeration with codes for ABI classification, coroutines, DWARF generation, CFI unwinding, and SIMD lowering. - Expression and Type Lowering (src/gcc_gen_be_expr.c, src/gcc_gen_be_type.c): - Expand lowering logic for complex expression operators, casts, initializers, and function calls. - Build System and Toolchain Configuration (CMakeLists.txt): - Prevent default selection of lld linker when building with Clang on Darwin. - Unit Testing and Documentation Coverage (tests/gcc_be/, dev_tools/): - Migrate and modernize backend unit tests using the GoogleTest framework. - Add test suites: test_dynamic_init.cpp, test_gcc_be_eh.cpp, test_gcc_be_error.cpp, test_gcc_be_location.cpp, test_gcc_be_regression.cpp, and generate_tests.py. - Expand Doxygen comments across headers and tests to satisfy coverage requirements. - Update check_gcc_be_coverage.sh and check_gcc_be_doc_coverage.py. --- CMakeLists.txt | 2 +- dev_tools/check_gcc_be_coverage.sh | 5 +- dev_tools/check_gcc_be_doc_coverage.py | 8 +- src/cfe.c | 11 +- src/cmd_line.c | 83 +- src/cmd_line.h

From: Samuel Marks <807580+SamuelMarks@users.noreply.github.com> Date: Sat, 17 Oct 2026 15:49:01 +1300 Subject: [PATCH 7/7] Complete GCC backend lowering for EH, coroutines, RTTI, multi-target ABI, and SIMD Expand the native libgccjit backend (gcc_gen_be), EDG frontend integration, runtime library, build presets, and test suites with full language feature lowering, multi-target calling conventions, exception handling tables, and 100% test and documentation coverage: - Exception Handling, Unwinding, and Runtime Bridge (src/gcc_gen_be_eh.[ch], lib_src/gcc_be_eh_rt.c): - Implement DWARF LSDA (.gcc_except_table) call-site, action, and type-info table generation with ULEB128/SLEB128 encoding and CFI directive formatting. - Add Windows SEH (.pdata/.xdata) and ARM EHABI (.ARM.extab/.ARM.exidx) unwind descriptor table synthesis. - Support direct and indirect invoke calls with abnormal unwind CFG edges, landing pad selector dispatch, noexcept/dynamic exception spec filters, partial array construction cleanups, and subobject unwind cleanups. - Add production SjLj/Itanium ABI runtime bridge (lib_src/gcc_be_eh_rt.c) providing frame registration and __cxa_type_match across SI/VMI hierarchies. - C++20 Coroutines, Statements, and Inline Assembly (src/gcc_gen_be_stmt.[ch], src/gcc_gen_be_expr.[ch]): - Implement coroutine frame layout/size/alignment computation, ramp lowering, resume/destroy state-machine dispatchers, suspension point registration, symmetric transfer, noop_coroutine singleton, and HALO elision checks. - Lower co_await and co_yield expressions and intrinsics. - Add VLA stack allocation lowering (gcc_gen_be_lower_vla_decl) and normalize read-modify-write ('+') inline assembly constraints into tied operands. - Multi-Target ABI Classification and Calling Conventions (src/gcc_gen_be_abi.[ch]): - Expand target ABI classifiers to cover System V AMD64, AAPCS64, Darwin ARM64, Windows x64, RISC-V LP64D, System V i386, PowerPC64 ELFv2, s390x, and AAPCS32. - Track cumulative GP/FP argument register pressure (gcc_gen_be_abi_reg_state_t), HFA/HVA packing, sret/invisible-reference lowering, and va_arg/va_list emission. - RTTI, Itanium Mangling, VTables, and Clones (src/gcc_gen_be_rtti.[ch], src/gcc_gen_be_decl.[ch]): - Implement Itanium C++ ABI name mangling for types, functions, expressions, and substitution tables (S_, S0_, ...). - Emit virtual-base offset (vcall) and covariant return adjustment thunks. - Synthesize C1/C2 constructor and D1/D2/D0 deleting destructor clones. - Support cross-platform COMDAT/weak-ODR section and linkage formatting across ELF, Mach-O, and COFF/PE, plus __dso_handle declaration in dtor. - Types, Decimal/Fixed-Point Arithmetic, and Builtins (src/gcc_gen_be_type.[ch], src/gcc_gen_be_builtin.[ch]): - Lower IEEE 754 decimal floating-point types (_Decimal32/_Decimal64/_Decimal128) and BID runtime arithmetic, comparisons, and conversions. - Implement ISO/IEC TR 18037 fixed-point (_Fract, _Accum, _Sat) scaled and saturating arithmetic, constant bitfield packing, and extended float constants. - Expand builtin and SIMD lowering for vector shuffle/permutation, __builtin_convertvector, atomic operations, and overflow intrinsics. - DWARF Debug Metadata, Driver, and Frontend Integration (src/gcc_gen_be_debug.[ch], src/gcc_gen_be_main.[ch], src/*, util/eccp.sh): - Add DWARF metadata emission for lexical scopes, inlined subroutines, namespaces, class inheritance, template parameters, and enumerations. - Implement multi-TU object linking (gcc_gen_be_link_multi_tu_objects) and C++20 module initializers (_ZGIW). - Enable BACK_END_IS_GCC_GEN_BE across EDG IL headers/allocators/layout and integrate --gcc-be / --gcc_gen_be into util/eccp.sh and CMakePresets.json. - Unit Tests and Coverage Tooling (tests/gcc_be/, dev_tools/): - Refactor unit and end-to-end tests to use standalone assertions (test_common.h) with full error percolation and Doxygen documentation. - Add dedicated test suites for target ABIs, bitfields, coroutines, DWARF debug, DWARF/SEH/ARM EH, full RTTI/mangling, SIMD, driver pipelines, and symbol loading. --- CMakePresets.json | 64 + cmake/FindLibGCCJIT.cmake | 6
