根因: 使用 32 位 gcc (i686) 构建 pcc，导致内部 PTR_SIZE=4， 生成 64 位目标时 TLS 目录按 32 位格式写入 (24字节而非40字节)， 所有含 __thread 变量的程序加载即崩溃。 修复: 改用 64 位 gcc (x86_64-w64-mingw32) 完整重建 pcc.exe， PTR_SIZE 正确为 8，TLS 目录 40 字节。 验证: - _Thread_local / __thread 程序正常运行 - _Generic, _Alignas, _Atomic, 匿名结构体, _Static_assert 全部通过 - tests2 套件 102 测试通过 (其余为 CRLF/路径/stderr 框架差异) - 自编译正常
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.
