tccpp: Implement __COUNTER__ This requires one more change in how macro arguments are expanded: the standard requires that macro args are expanded before substituting into the replacement list. This implies expanding them only once even when they occur multiple times in the list. TCC expanded them repeatedly in that case. Without __COUNTER__ that's harmless. So, simply always expand arguments (when used without # and ##) once and store the resulting tokens.

Handle always_inline as GNU inline this is needed for multi-file testcases using stdio.h, as the __sputc function is implemented as a extern inline function (with gnu_inline attribute, but we don't support that for now). Without this change that leads to multiply defined symbols when using multiple units including stdio.h. It also has an always_inline attribute, which we can use to guide our behaviour, as in ISO-C an always_inline can't be defined with ISO 'extern inline' semantics. This is the minimal change and not a full implementation of GNU inline semantics, which would require thorough testcases. If __clang__ would be defined the header would make use of C99 semantics, which would work for us. It would also do that if _GNUC_ wouldn't be defined. But we can't do the latter (as the whole MacOSX SDK refuses to be compiled with anything not defining that). I haven't tested defining __clang__, but suspect that's going to be problematic.

stdarg: always have the __builtin_va_* available This makes available the __builtin_va_list type and __builtin variants of va_start, va_arg, va_copy and va_end. We do this via a header file that's prepended to all compilations always (except if merely preprocessing): tcc_predefs.h. That header could also be used for predefining other builtins in the future. We don't need the define hacks for musl anymore with this. Also fix x86_64 gfunc_prologue to reserve enoug space for the full va_list structure, not just 16 bytes.

riscv: implement stdarg functions this also fixes passing of params > 16 bytes. In riscv they aren't passed by value on stack, but via reference (and because callees are allowed to modify by-ref params the caller must allocate an own copy per call). This fixes the stdarg parts of 73_arm.c.

Runtime lib functions Yesterday I felt the urge to change a few things in TinyCC. This is the first and biggest change of all of them. - use __aeabi_*divmod functions in ARM EABI to make binaries depend solely on standardized library functions - refactor ARM floating point <-> integer conversion a bit - rename long long->float and shift library functions to correspond to the names used by GCC - compile more tokens conditionally to reduce the size of TinyCC The intention is primarily to allow users of the ARM target to use libgcc (which is usually available as a shared library) instead of libtcc1 (which can't be compiled for ARM due to lack of an inline assembler). Changing the EABI target to use the divmod functions in theory allows to use it without libtcc1 on any (not necessarily GCC based) ARM EABI system. Daniel

riscv: some work on large function arguments like long double (16 bytes) and structs. Not completely correct, but 73_arm64 somewhat works now (when the stdarg part is disabled), though with some errors. What's definitely incorrect is arguments of a mixed int/float struct. I'm using VT_LDOUBLE (which conveniently has to be placed in a int-reg-pair) to load/store structure arguments of size > 8 and <= 16, and that can lead to overreads.

bcheck cleanup - revert Makefiles to state before last bcheck additions Instead, just load bcheck.o explicitly if that is what is wanted. - move tcc_add_bcheck() to the <target>-link.c files and remove revently added arguments. This function is to support tccelf.c with linking, not for tccgen.c to support compilation. - remove -ba option: It said: "-ba Enable better address checking with bounds checker" Okay, if it is better then to have it is not an option. - remove va_copy. It is C99 and we try to stay C89 in tinycc when possible. For example, MS compilers do not have va_copy. - win64: revert any 'fixes' to alloca It was correct as it was before, except for bound_checking where it was not implemented. This should now work too. - remove parasitic filename:linenum features Such feature is already present with rt_printline in tccrun.c. If it doesn't work it can be fixed. - revert changes to gen_bounded_ptr_add() gen_bounded_ptr_add() was working as it should before (mostly). For the sake of simplicity I switched it to CDECL. Anyway, FASTCALL means SLOWCALL with tinycc. In exchange you get one addition which is required for bounds_cnecking function arguments. The important thing is to check them *BEFORE* they are loaded into registers. New function gbound_args() does that. In any case, code instrumentation with the bounds-check functions as such now seems to work flawlessly again, which means when they are inserted as NOPs, any code that tcc can compile, seems to behave just the same as without them. What these functions then do when fully enabled, is a differnt story. I did not touch this.
