This needs to return ops[0].value instead, since "target" just suggests
a possible location.
Could you add tests for a memory source and memory destination, e.g.:
void test_clz_mem (uint32_t *a)
{
*a = __clz (*a);
}
Without tests like that, these comments probably just sound like a paper
exercise, but they should make a difference for memory sources (previous
review) and memory destinations (this round).
I had locally tested it (with rev though because clz doesn't use that
code) and strangely it does seem to work for the memory destinations,
but that's just a simple test.
It could very well go wrong with some more complex codegen, so I'll just
take your word and use ops[0].value.
And yeah I didn't add the tests at the time, don't really know why, I'll
chuck it down to laziness :P

The return type should be int16_t.
Nice catch!
The clz and cls tests have the old return types (same as the argument
types), but I guess that's a good thing, since it shows that we avoid
the redundant zero-extend in clzll and clsll.
Yeah I noticed that too when I was adding the mem tests, but I did
change them though because at the time it just felt like an oversight,
though I too was pleasantly surprised GCC was managing to avoid the
zero-extending :)
I then saw your comment and made me wonder whether I should keep the
wrong return types in... I haven't but happy to change them back if you
think it's a nice 'test' to have.
Regards,
Andre
