Conversation
- Decouple fixup storage from the machine code buffer. - Introduce a statically allocated 'fixups' buffer. - Simplify 'push_fixup' by implicitly capturing 'cgc_fs'. - Add generic accessors for fixup node data. - Update label and goto resolution logic to use the new buffer.
- Modify 'emit_i8' to pack 4 bytes per 'int' using bitwise operations. - Update 'generate_exe' in elf.c and mach-o.c to unpack bytes before writing to output. - Reduce CODE_SIZE and adjust 'code' array declaration to significantly reduce BSS memory usage. - Update 'emit_i8' bounds check to match the new byte capacity.
