tccpe.c: - fix arm64 unwind codes (to make native set/longjmp() work) sizeof(RUNTIME_FUNCTION) is 8 on arm64 in the first place no need to note stack slots if we don't save any registers anyway arm64-gen.c: - fix long double reg-move - fix arm64_hfa() for structs with float arrays - gfunc_prolog(): setup stackframe eariler (simplifies unwind codes) - new function gv_addr(RC); win32/include/setjmp.h: - provide correct definition for setjmo() (frameoffset = 224) tccasm.c: - support ".quad" with symbol & relocation - support ".size" - fix ". - symbol" arithmetic win32/lib/crt1.c and win32/include/stdlib.h: - do not write to __argc/__argv which reside in msvcrt.dll (msvcrt.dll on arm64 does not like that, crashes on unload) tcc.c,libtcc.c: - new functions tcc_fopen/fclose to avoid different stdio unstances in tcc.exe & libtcc.dll tests & github workflow: - add test-win32.bat to run tests with a tcc compiled by build-tcc.bat - add msvcrt_start.c for gcc/clang to use the same runtime as tcc the problem is that newer gcc as well as clang and cl are linking to newer runtimes (such as UCRT) that have partially different printf format behavior which makes tcctest fail. the solution here is to force these compilers to link with msvcrt.dll just like tcc. Also, there is no gcc on arm64-win32 currently at all. Anyway, this approach to running the github CI tests does not require msys2. But It does rely on gnumake as well as on some 'sh' shell though which seems to be installed somewhere (maybe it is the one from git).
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.
