Re: [PATCH] fix trap in parallel for m32r-sim

[Kazuhiro Inaoka <inaoka dot kazuhiro at renesas dot com>]

Hi Doug,

I want to fix the following problem.

test pattern is:
main()
{
  asm("trap #0 || ldi r0,#1"); /* the same as exit() ? */

  abort();
}

command line:
m32r-elf-gcc -m32rx test.c

In this case, it will pass through an asm function without exit.
At the time of m32r_trap() execution, r0 is not 1 yet.
It's not a problem of the current simulator implementation for trap
instruction.
I think it's a problem of timing to call back system call when trap is in
parallel.

Changed a patch and comment.
