           Summary: [inlineasm] 's' constraint bug
           Product: libraries
           Version: trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Common Code Generator Code
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: sabre at nondot.org


This testcase:
int x[2] = { 1, 2 };
static inline void __attribute__((__always_inline__))
insn1 (int x) {
  asm volatile ("" :: "n" (x), "i" (x));
}
static inline void __attribute__((__always_inline__))
insn2 (const void *x) {
  asm volatile ("%0 %1" :: "s" (x), "i" (x));
}

void foo (void) {
  insn2 (&x[1]);
}

Should compile to:

_foo:
        _x+4 _x+4
        blr

We currently produce:

Invalid operand for inline asm constraint 's'!
