I've checked this issue again on rev 192482.  It seems to be target
independent, as it also happens on ARM.
The following:

static inline int readint (int* x)
{
  return *x;
}

int test (int* x)
{
  return readint (x);
}

compiles to (-O2):

test:
        ldrb    r3, [r0]
    ldrb    r1, [r0, #1]
    ldrb    r2, [r0, #2]
    orr    r3, r3, r1, asl #8
    ldrb    r0, [r0, #3]
    orr    r3, r3, r2, asl #16
    orr    r0, r3, r0, asl #24
