<pre>Created <span class=""><a href="attachment.cgi?id=10047" name="attach_10047" title="The IR Module">attachment 10047</a> <a href="attachment.cgi?id=10047&action=edit" title="The IR Module">[details]</a></span>
The IR Module
Given the following LLVM IR:
define void @t1(i32* nocapture %a) {
ret void
}
declare void @t1.a(i32 %c, i32)* %a)
F = @t1
F2 = @t1.a
I = Argument[0] of @t1
I2 = Argument[1] of @t1.a
if I then do:
I2->addAttr(F->getAttributes()
.getParamAttributes(I->getArgNo() + 1));
Instead of I2 getting the attribute, Argument[0] gets it, and it ends up as:
declare void @t1.a(i32 nocapture %c, i32* %a)
when it should be:
declare void @t1.a(i32 %c, i32* nocapture %a)
F->getAttributes().dump()
PAL[
{ 1 => nocapture }
]
F2->getAttributes().dump()
PAL[
{ 1 => nocapture }
]
I'm guessing this second dump should be "2 => nocapture".</pre>
