Re: [PATCH v1] RISC-V: Implement .SAT_SUB for unsigned vector int

[Robin Dapp]

Hi Pan,

in general LGTM.  Would you mind adding the coremark-pro
testcase which should be working now, and, was the original
reason for doing this?

I believe the following should do:

extern int wsize;

typedef unsigned short Posf;
#define NIL 0

void foo (Posf *p)
{
  register unsigned n, m;
  do {
      m = *--p;
      *p = (Posf)(m >= wsize ? m-wsize : NIL);
  } while (--n);
}

Regards
 Robin
