New Revision: 299899<br>
<br>
URL: <a href="http://llvm.org/viewvc/llvm-project?rev=299899&view=rev" rel="noreferrer" target="_blank">http://llvm.org/viewvc/llvm-<wbr>project?rev=299899&view=rev</a><br>
Log:<br>
Reland "[IR] Make AttributeSetNode public, avoid temporary AttributeList copies"<br>
<br>
This re-lands r299875.<br>
<br>
I introduced a bug in Clang code responsible for replacing K&R, no<br>
prototype declarations with a real function definition with a prototype.<br>
The bug was here:<br>
<br>
// Collect any return attributes from the call.<br>
- if (oldAttrs.hasAttributes(llvm::<wbr>AttributeList::ReturnIndex))<br>
- newAttrs.push_back(llvm::<wbr>AttributeList::get(newFn-><wbr>getContext(),<br>
- oldAttrs.getRetAttributes()));<br>
+ newAttrs.push_back(oldAttrs.<wbr>getRetAttributes());<br>
<br>
Previously getRetAttributes() carried AttributeList::ReturnIndex in its<br>
AttributeList. Now that we return the AttributeSetNode* directly, it no<br>
longer carries that index, and we call this overload with a single node:<br>
AttributeList::get(<wbr>LLVMContext&, ArrayRef<AttributeSetNode*>)<br>
<br>
That aborted with an assertion on x86_32 targets. I added an explicit<br>
triple to the test and added CHECKs to help find issues like this in the<br>
future sooner.<br>
