Tiny C Compiler by Fabrice Bellard Git mirror of the final release by Bellard, discarding all changes after. The repository at https://repo.or.cz/tinycc.git has become untrustworthy. Also the tcc sources have become tainted with AI slop. https://git.datenwolf.net/tinycc/atom/stdarg.h?h=main 2009-04-18T13:08:03Z 2009-04-18T13:08:03Z grischka grischka 2009-04-18T12:28:45Z urn:sha1:ea5e81bd6a3376232bf4747b2fa2e0a91c19b337 2009-04-18T13:07:09Z Shinichiro Hamaji shinichiro.hamaji _at_ gmail.com 2009-03-31T18:45:18Z urn:sha1:ebb874e2164308b1b9a53a2b1f6d1b9f65894059 We need malloc and free to implement va_start and va_end. Since malloc and free may be replaced by #define, we add __builtin_malloc and __builtin_free. 2008-12-02T01:30:47Z Shinichiro Hamaji shinichiro.hamaji _at_ gmail.com 2008-12-01T18:19:25Z urn:sha1:0a9873aa22731077fad295a4aad2fc1f390c8ac7 Most change was done in #ifdef TCC_TARGET_X86_64. So, nothing should be broken by this change. Summary of current status of x86-64 support: - produces x86-64 object files and executables. - the x86-64 code generator is based on x86's. -- for long long integers, we use 64bit registers instead of tcc's generic implementation. -- for float or double, we use SSE. SSE registers are not utilized well (we only use xmm0 and xmm1). -- for long double, we use x87 FPU. - passes make test. - passes ./libtcc_test. - can compile tcc.c. The compiled tcc can compile tcc.c, too. (there should be some bugs since the binary size of tcc2 and tcc3 is differ where tcc tcc.c -o tcc2 and tcc2 tcc.c -o tcc3) - can compile links browser. It seems working. - not tested well. I tested this work only on my linux box with few programs. - calling convention of long-double-integer or struct is not exactly the same as GCC's x86-64 ABI. - implementation of tcc -run is naive (tcc -run tcctest.c works, but tcc -run tcc.c doesn't work). Relocating 64bit addresses seems to be not as simple as 32bit environments. - shared object support isn't unimplemented - no bounds checker support - some builtin functions such as __divdi3 aren't supported 2006-10-28T19:45:50Z bellard bellard 2006-10-28T19:45:50Z urn:sha1:84f4e9963569f930feaa536d03f98c448cb1d75c 2003-01-06T20:22:23Z bellard bellard 2003-01-06T20:22:23Z urn:sha1:50f0ae610feddcf73439c3a600ffdcd946813662 2002-08-31T12:43:53Z bellard bellard 2002-08-31T12:43:53Z urn:sha1:5c81896e06ae72da7a976c2ebf808fffb01bd430 2001-11-11T18:01:29Z bellard bellard 2001-11-11T18:01:29Z urn:sha1:eb0e3e70dcb42dd60122158e1b9dbdcd0fac3a3e 2001-11-11T02:54:21Z bellard bellard 2001-11-11T02:54:21Z urn:sha1:b536ac306846dcb1639bb15bda1131063103458c
