<pre>Created <span class=""><a href="attachment.cgi?id=14567" name="attach_14567" title="testcase.ll">attachment 14567</a> <a href="attachment.cgi?id=14567&action=edit" title="testcase.ll">[details]</a></span>
testcase.ll
I have the following reduced testcase file:
<span class="quote">> cat testcase.ll</span >
define i32 @foo(i32 %a, i32 %b) {
entry:
%0 = call i32 asm "", "=r,r,n,n"(i32 %a, i32 %b, i32 %b)
ret i32 %0
}
When invoking llc on the above file I get this error:
<span class="quote">> llc testcase.ll</span >
error: invalid operand for inline asm constraint 'n'
<span class="quote">> clang -v</span >
clang version 3.7.0 (<a href="https://urldefense.proofpoint.com/v2/url?u=http-3A__llvm.org_git_clang.git&d=AwMBaQ&c=8hUWFZcy2Z-Za5rBPlktOQ&r=pF93YEPyB-J_PERP4DUZOJDzFVX5ZQ57vQk33wu0vio&m=W4CWMr4M2aFOQq6aXDcKUTsMVPAuodEtMrPNj9NjTvw&s=_lTcknsdwE02YXq3c3RSuJz2I4C19m22lFoF2kqjuSM&e=">http://llvm.org/git/clang.git</a>

Thread model: posix
Note: There is bug on a similar issue:
<a class="bz_bug_link
bz_status_RESOLVED bz_closed" title="RESOLVED WONTFIX - error in backend: Invalid operand for inline asm constraint 'i'!" href="show_bug.cgi?id=11657">https://llvm.org/bugs/show_bug.cgi?id=11657</a>
However the asm in that bug was malformed. I am not sure whether the asm in my
testcase is malformed. Could someone please comment?</pre>
