Re: [Tinycc-devel] Crash on static function when compiling with -nostdlib
Hi Oren,
Unfortunately, tcc –v does not indicates precisely the version you use.
I can just say that I can’t reproduce with mob. The official 0.9.27 is really
old. Please use mod instead.

the following code, when compiled with tcc -nostdlib caused tcc to segafult
$ cat testcase.c
static void test () {;}
void _start() {;}
$ tcc testcase.c -nostdlib
Segmentation fault (core dumped)
$ tcc -v
tcc version 0.9.27 (x86_64 Linux)
I did some variations and it seems it's just any "static" function definition,
causes segfault when compiling without standard library.

It would be nice if tcc -v specified the git commit it was built on.

Re: [Tinycc-devel] Crash on static function when compiling with -nostdlib
I fully agree with you, I already asked the same thing on this list (git
version + commit date) but got no replies L
Also the last official 0.9.27 is quite old (> 3y) it would be nice to update
the official version.

[Tinycc-devel] I want to add more info with -v option
Hi, More and more users complain with 0.9.27 bugs which are solved by mob. They often tell us they are using ./tcc -v => 0.9.27 which is meaningless as 0.9.27 is anything form last >3y old official 0.9.27 to mob. To improve this, I would like to add the git last date (or anything that can easily identify the source code version used to compile tcc). ./tcc -v jullien@sims4:~/tinycc $ ./tcc -v tcc version 0.9.27 (ARM eabihf Linux - git version Thu Mar 18 22:54:24 2021) When tcc is compiled from a tarball (w.o. git info) it will tell: jullien@sims4:~/tinycc $ ./tcc -v tcc version 0.9.27 (ARM eabihf Linux - unknown git version) Can I push this patch? jullien@sims4:~/tinycc $ git diff diff --git a/Makefile b/Makefile index 6d09b65..691a2d3 100644 --- a/Makefile +++ b/Makefile @@ -24,6 +24,12 @@ CFLAGS += -I$(TOP) CFLAGS += $(CPPFLAGS) VPATH = $(TOPSRC) +TCC_GIT_DATE=$(shell which gut > /dev/null 2>&1 && git log -1 --format=%ad --date=local || echo no) + +ifneq ($(TCC_GIT_DATE),no) + CFLAGS += -DTCC_GIT_DATE="\"$(TCC_GIT_DATE)\"" +endif + ifdef CONFIG_WIN32 CFG = -win ifneq ($(CONFIG_static),yes) diff --git a/tcc.c b/tcc.c index bd9ce2f..36f4af1 100644 --- a/tcc.c +++ b/tcc.c @@ -181,6 +181,12 @@ static const char version[] = " NetBSD" #else " Linux" +#endif +#ifdef TCC_GIT_DATE +" - git version " +TCC_GIT_DATE +#else +" - unknown git version" #endif ")\n" ; ___ Tinycc-devel mailing list Tinycc-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/tinycc-devel

Of course it’s git. I use gut to test the case git is not installed.

I also think the hash should be there. git describe can be useful here too. On Wednesday, March 31, 2021, 06:44:39 PM GMT+3, Dmitry Selyutin wrote: Hi Jullien, I think this is a really good idea.

Re: [Tinycc-devel] I want to add more info with -v option
It appears some prefer git hash so I added short hash. Code is commited, you should get something like: $ ./tcc -v tcc version 0.9.27 - 65d00b1 (ARM eabihf Linux) Now, anything wo. hash is not from mod. C.
