<br>
I'm working on the XCore target which does not (nor is there a reason to) handle stack alignment other than 4 byte.<br>
It seems sensible therefore to explicitly set TargetFrameLowering to use:<br>
TransientStackAlignment = 4, StackRealignable= false<br>
<br>
"If a constant alignment is specified, the value result of the allocation is guaranteed to be aligned to at least that boundary"<br>
Thus should I expect an error if I compiled the following?<br>
declare void @f1(i32*, i32*)<br>
define void @f2() nounwind {<br>
entry:<br>
%0 = alloca i32, align 1<br>
%1 = alloca i32, align 16<br>
call void @f1(i32* %0, i32* %1)<br>
ret void<br>
}<br>
The output currently seems to ignore the 'align' and uses 4 byte alignment on the stack.<br>
<br>
Thank you.<br>
<br>
