实现 C++ 到 C 的转换器 (tools/pcc-cpp.c),pcc 检测 .cpp 文件时
自动转换后编译。阶段 1 支持:
1. class 定义 → struct (数据成员 + 继承的 __base 嵌套)
2. 成员函数 (类内声明/类外定义/内联定义)
- 名称修饰: Class::method → Class_method
- 自动添加 this 参数: (struct Class *this)
- 方法体内裸成员名 → this->member
- 基类成员 → this->__base.member
3. 构造函数/析构函数
- 名称修饰: Class::Class → Class_ctor, ~Class → Class_dtor
- 局部对象声明时自动调用构造
- 支持带参构造 (var(a,b) → Ctor(&var, a, b))
- 初始化列表跳过 (: Base(args))
4. 成员调用: obj.method(args) → Class_method(&obj, args)
5. 继承: class B : public A → struct B { struct A __base; }
6. 简单继承的成员访问/方法遮蔽
同时修复:
- AFF_TYPE_CPP 与 AFF_PRINT_ERROR 位冲突 (0x10)
- #pragma pack(push,MACRO) 宏展开 (x86_64 下 TOK_ASM_push 未定义)
- 头文件 _CRT_PACKING pragma 改为数字
验证: pcc test.cpp 直接编译运行, 含继承/构造/成员的程序 exit=0
Tiny C Compiler - C Scripting Everywhere - The Smallest ANSI C compiler ----------------------------------------------------------------------- Features: -------- - SMALL! You can compile and execute C code everywhere, for example on rescue disks. - FAST! tcc generates machine code for i386, x86_64, arm, aarch64 or riscv64. Compiles and links about 10 times faster than 'gcc -O0'. - UNLIMITED! Any C dynamic library can be used directly. TCC is heading toward full ISOC99 compliance. TCC can of course compile itself. - SAFE! tcc includes an optional memory and bound checker. Bound checked code can be mixed freely with standard code. - Compile and execute C source directly. No linking or assembly necessary. Full C preprocessor included. - C script supported : just add '#!/usr/local/bin/tcc -run' at the first line of your C source, and execute it directly from the command line. Documentation: ------------- 1) Installation on Linux, BSD variants or macOS hosts: ./configure make make test make install Notes: On BSD hosts, gmake should be used instead of make. For Windows read tcc-win32.txt. makeinfo must be installed to compile the doc. By default, tcc is installed in /usr/local/bin. ./configure --help shows configuration options. 2) Introduction We assume here that you know ANSI C. Look at the example ex1.c to know what the programs look like. The include file <tcclib.h> can be used if you want a small basic libc include support (especially useful for floppy disks). Of course, you can also use standard headers, although they are slower to compile. You can begin your C script with '#!/usr/local/bin/tcc -run' on the first line and set its execute bits (chmod a+x your_script). Then, you can launch the C code as a shell or perl script :-) The command line arguments are put in 'argc' and 'argv' of the main functions, as in ANSI C. 3) Examples ex1.c: simplest example (hello world). Can also be launched directly as a script: './ex1.c'. ex2.c: more complicated example: find a number with the four operations given a list of numbers (benchmark). ex3.c: compute fibonacci numbers (benchmark). ex4.c: more complicated: X11 program. Very complicated test in fact because standard headers are being used ! As for ex1.c, can also be launched directly as a script: './ex4.c'. ex5.c: 'hello world' with standard glibc headers. tcc.c: TCC can of course compile itself. Used to check the code generator. tcctest.c: auto test for TCC which tests many subtle possible bugs. Used when doing 'make test'. 4) Full Documentation Please read tcc-doc.html to have all the features of TCC. Additional information for the Windows port is in tcc-win32.txt.
