- 成员运算符: Class::operator+ -> Cls_add (类内定义 + 外部定义) - 自由运算符: Vec operator+(Vec a, Vec b) -> Cls_add(struct Cls *this, struct Cls b) 首参重写为 this, 函数体内引用重写 (a.x -> this->x) - 表达式转换: var = a op b -> var = Cls_op(&a, b); var1 op var2 -> Cls_op(&v1, v2) - 修复: struct 类路由到 parse_class (消除 T_STRUCT 逐字复制死循环) - 修复: 局部类变量 Complex r; 非破坏性 peek (read_tok 重写) - 修复: 多声明符 Cls a, b; 记录所有变量 - 修复: 无 ctor 类的运算符赋值不再被 has_ctor 门槛挡住 - 修复: 外部定义 Counter::inc() 丢失 next_tok 回归 - 新: 派生类 ctor 自动链式调用基类默认 ctor - 新: tokenizer 跳过 UTF-8 BOM
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.
