TODO list: Releases: - release tcc on a regular basis- testing repo.or.cz Bugs: - i386 fastcall is mostly wrong- FPU st(0) is left unclean (kwisatz haderach). Incompatible with  optimized gcc/msc code- see transparent union pb in /urs/include/sys/socket.h- precise behaviour of typeof with arrays ? (__put_user macro)  but should suffice for most cases)- handle '? x, y : z' in unsized variable initialization (',' is  considered incorrectly as separator in preparser)- transform functions to function pointers in function parameters  (net/ipv4/ip_output.c)- fix function pointer type display- check section alignment in C- fix invalid cast in comparison 'if (v == (int8_t)v)'- finish varargs.h support (gcc 3.2 testsuite issue)- fix static functions declared inside block- fix multiple unions init- make libtcc fully reentrant (except for the compilation stage itself).- struct/union/enum definitions in nested scopes (see also Debian bug #770657)- __STDC_IEC_559__: float f(void) { static float x = 0.0 / 0.0; return x; }- memory may be leaked after errors (longjmp). Portability: - it is assumed that int is 32-bit and sizeof(int) == 4- int is used when host or target size_t would make more sense- TCC handles target floating-point (fp) values using the host's fp  arithmetic, which is simple and fast but may lead to exceptions  and inaccuracy and wrong representations when cross-compiling Linking: - static linking (-static) does sort of work	works with musl libc	glibc requires libc.so even when statically linked (very bad, but not	up to tcc) Bound checking: - fix bound exit on RedHat 7.3- setjmp is not supported properly in bound checking.- fix bound check code with '&' on local variables (currently done  only for local arrays).- bound checking and float/long long/struct copy code. bound  checking and symbol + offset optimization Missing features: - disable-asm and disable-bcheck options- __builtin_expect()- atexit (Nigel Horne)- C99: add complex types (gcc 3.2 testsuite issue)- postfix compound literals (see 20010124-1.c)- interactive mode / integrated debugger Optimizations: - suppress specific anonymous symbol handling- more parse optimizations (=even faster compilation)- memory alloc optimizations (=even faster compilation)- optimize VT_LOCAL + const- better local variables handling (needed for other targets) Not critical: - C99: fix multiple compound literals inits in blocks (ISOC99  normative example - only relevant when using gotos! -> must add  boolean variable to tell if compound literal was already  initialized).- add PowerPC generator and improve codegen for RISC (need  to suppress VT_LOCAL and use a base register instead).- fix preprocessor symbol redefinition- add portable byte code generator and interpreter for other  unsupported architectures.- C++: variable declaration in for, minimal 'class' support.- win32: __intxx. use resolve for bchecked malloc et al.  check exception code (exception filter func).- handle void (__attribute__() *ptr)()- VLAs are implemented in a way that is not compatible with signals:  http://lists.gnu.org/archive/html/tinycc-devel/2015-11/msg00018.html Fixed (probably): - bug with defines:    #define spin_lock(lock) do { } while (0)    #define wq_spin_lock spin_lock    #define TEST() wq_spin_lock(a)- typedefs can be structure fields- see bugfixes.diff + improvement.diff from Daniel Glockner- long long constant evaluation- add alloca()- gcc '-E' option.- #include_next support for /usr/include/limits ?- function pointers/lvalues in ? : (linux kernel net/core/dev.c)- win32: add __stdcall, check GetModuleHandle for dlls.- macro substitution with nested definitions (ShangHongzhang)- with "-run" and libtcc, a PLT is now built.- '-E' option was improved- packed attribute is now supported- ARM and ARM64 code generators have been added.
