hello the above program gives me:

I know TinyC does not optimize (that's why it's fast and that's what I
love) but having to write macros for performance feels so obsolete,
double evaluation hiding in dark corners etc. And function calls are
so expensive in tight loops. Is there a way in Tiny to tell the
compiler always to inline
I remember #line was limited to 65535 on tcc recently, but now it is
limited to 294967295 (max int32), when this was changed?
Also I think it should be 42949672965 instead (max uint32) as in GCC and Clang.

I have tried the last zero length member extension in tcc and
compilation succeeded but the program crashes, is this a bug or a
different implementation? Btw if you do not know this is a super
useful extension.
typedef struct {
int size;
What's the current state of affairs with tcc on mac? I can't either find
the working compiler nor the explanation on why it is not found. There must
be something to proprietary binary format prolly. Please share if you know
anything.

Hi,
I am using TCC as a backend for another programming language (my own), I
need a stack trace functionality. I already ranted that backtrace and
backtrace_symbols do not work with TCC for me, so I ended up writing my own
backtrace() to get a list of return adresses, and then I am calling
I read OP's question differently, it seemed he wanted to know more about
the intrinsics of TinyCC in regards to various instruction set supports
rather than to know more about ARM technology in general? OR maybe "how
advanced is the support of ARM in TCC"? If it was worded as "how do you add
a new
It works as expected for GCC, but TinyC will always print prog.c ignoring
the argument.
Latest tcc from git. Ubuntu. x86_64. Musl. (Because GNU LibC does not work
with addr2line).
Thanks,
Yakov

Any idea why I get ??:? instead of a line number?
