Bugs:
|
|
|
|
- fix macro substitution with nested definitions (ShangHongzhang)
|
|
- FPU st(0) is left unclean (kwisatz haderach). Incompatible with
|
|
optimized gcc/msc code
|
|
|
|
- constructors
|
|
- cast bug (Peter Wang)
|
|
- define incomplete type if defined several times (Peter Wang).
|
|
- test binutils/gcc compile
|
|
- tci patch + argument.
|
|
- see -lxxx bug (Michael Charity).
|
|
- 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 lcc test suite -> fix bitfield binary operations
|
|
- 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
|
|
- sizeof, alignof, typeof can still generate code in some cases.
|
|
- Fix the remaining libtcc memory leaks.
|
|
- make libtcc fully reentrant (except for the compilation stage itself).
|
|
|
|
Bound checking:
|
|
|
|
- '-b' bug.
|
|
- 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()
|
|
- improve '-E' option.
|
|
- atexit (Nigel Horne)
|
|
- packed attribute
|
|
- C99: add complex types (gcc 3.2 testsuite issue)
|
|
- postfix compound literals (see 20010124-1.c)
|
|
|
|
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 or ARM code generator and improve codegen for RISC (need
|
|
to suppress VT_LOCAL and use a base register instead).
|
|
- interactive mode / integrated debugger
|
|
- fix preprocessor symbol redefinition
|
|
- better constant opt (&&, ||, ?:)
|
|
- 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)()
|
|
|
|
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.
