Hi! The following test hangs when compiled with tcc after 737f98421
tccgen.c: Bug fix for 992cbda and 3ff77a1: set nocode_wanted.
tests/tests2/78_vla_label.*: Add test
fantoo 222 # ./vla_label_fix_problem.sh
begin
timeout=2
extern int printf(const char *format, ...);
static void kb_wait(void)
{
unsigned long timeout = 2;
do {
(1 ?.
printf("timeout=%ld\n", timeout) :
({
unsigned long msec=1;
while (msec--)
printf("error\n");
})
);
timeout--;
} while (timeout);
}
int main()
{
printf("begin\n");
kb_wait();
printf("end\n");
return 0;
}
PS: this problem cause tccboot kernel (linux 2.4.26) to hang when using
current tcc to compile it (only on real hardware, no problem with my
version of the VirtualBox)
PPS: tccboot sources will be placed on github soon. tcc compiler is used to
compile kernel and ISO image produced.
