-TODO list:
-
-Releases:
-- release tcc on a regular basis (which interval? 3 months?)
-
-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.
