- Subject: Simulator question about argc/argv
Some new tests have been added to the GCC testsuite (cilk tests) that
check the value of argc and they expect it to be 1 if there are no
arguments to the test program (and there are none) but I am getting 0
when I run the tests under the gnu simulator. Does anyone know why
this is? I don't know if this is specific to my target (mips-mti-elf)
or a general simulator problem. Perhaps it is related to my linker
script? The mips-mti-elf target is built with newlib. Could someone
else who uses the gnu simulator and newlib try this. It works fine for
me under the qemu simulator.
% cat x.c
#include <stdio.h>
int main(int argc, char **argv)
{
printf("%d\n", argc);
return 0;
}
% mips-mti-elf-gcc x.c -Tmti32.ld -o x
% mips-mti-elf-run ./x
0
% mips-mti-elf-run ./x 99
0
