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 -
