Add __attribute__((constructor)) to __bounds_init. - remove tcc_add_bcheck from i386-link.c and x86_64-link.c - add simplified tcc_add_bcheck to tccelf.c - Update tccrun.c to call constructor/destructor. Set dynsym sh_info to number of local symbols in tccelf.c Reduce stack size when bounds checking is enabled. Added variable TCC_LIBBCHECK for windows support. Add signal stack to detect stack overflow. Add all & parameters in lbound_section and remove them if not used. Close fd in tcc_relocate in tccrun.c Fix section type constructor/destructor in tccelf.c Add check code in tests/boundtest.c for mem/str functions. Remove -ba from documentation. Add bounds check signal info in documentation. bcheck.c: - Fix initial_pool alignment. . Fix printf statements. . Add prototypes for all external interface functions. - Add TCC_BOUNDS_WARN_POINTER_ADD environment variable. . Add ctype and errno data. - Fix alloca when multithreading is used. - Add lock for __bound_checking and __bound_never_fatal. - Catch pthread_create and use locks when called. - Detect in loaded in shared lib and use locks when found - Use spin locks instead of semaphore locks. - Make spin locked code as small as possible. - Fix mem/str functions checking. - Fix overlap checking mem/str functions.
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 optimized x86 code. No byte code overhead. Compile, assemble and link about 7 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 a i386/x86_64/arm Linux/OSX/FreeBSD host ./configure make make test make install Notes: For OSX and FreeBSD, 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 is available for the Windows port in tcc-win32.txt.
