<pre>Using llc built from r214897...unpleasant surprise:
$ cat foo.ll
define <4 x float> @fneg4(<4 x float> %x) #0 {
%sub = fsub <4 x float> zeroinitializer, %x
ret <4 x float> %sub
}
$ ./llc -mtriple=x86-64 foo.ll -o -
...
movi v1.2d, #0000000000000000
fsub v0.4s, v1.4s, v0.4s
ret
---------------------------------------------------------
That's not x86-64.
I typo'd the triple for "x86_64". It would be nicer if the tools warned on
invalid params.
There is a warning for a bad -mcpu value sometimes...or not: <a class="bz_bug_link
