workflow: - revert 'pinact for security' for readability from831c3fa184tccpp.c: - remove code that allows tcc to parse numbers incorrectly (*) from829c848520tccgen.c: - Revert "Relaxed the 'incompatible pointer type' warning a bit" (*) fromd9ec17d334. tccrun.c: - remove support for -nostdlib -run for simplicity, we require "main" with tcc -run always tccpp.c: - Revert "Free all preprocessor memmory in case of error." fromc96f0cad61Remove TinyAlloc->limit instead. Thus it can do also bigger allocs. Big TokenStrings (like 200kb+ when compiling tcc) may come from inline functions or from large initializers. Makefile/configure: - use --config-pie for configuring tcc output only - use -fPIC with clang-x86_64 to avoid 32-bit relocs libtcc.c: - fix "tcc file.c -run" i.e. -run as last argument i386-gen.c: - PIC refactor (*) sorry, but code in tcc should have a minimum of generic relevance
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.
