RE: [Qemu-devel] [PATCH 0/2] ARM: fix commandline handling forsemihosted executables

[Schildbach, Wolfgang]

Hi Riku, 

I usually compile a hello world (echoing its arguments) with rvds2.2 or
above:

#include <stdio.h>

int main(int ac, char *av[])
{
  int i;
  printf("Hello world\n");
  for (i=0; i<ac; i++)
    printf("'%s'\n", av[i]);
  return 0;
}

> armcc -o hello -L--sysv hello.c

I configure qemu like this:

> ./configure '--prefix=/data/project/qemu/latest'
'--target-list=arm-linux-user'
> gmake install

...and execute it, checking whether the execution echoes back the
arguments:

> /data/project/qemu/latest/bin/qemu-arm hello a
"hello"
"a"

If you don't have an ARM compiler available, I could send you the
compiled binary to test. Peter, is there another way to generate
binaries using semihosting?

Best regards,
- Wolfgang

Hi,

Honestly, I have never tried ARM semihosting. Do you have some
recommended test instructions?
