[llvm-dev] How to add/use parameter attributes? Troubles with "byval"
edA-qa mort-ora-y via llvm-dev
I need to create a function like this:
%1 = call i64 @abi_call_test_tuple_2p(%struct.abi_tuple_2p* byval
align 8 %v)
Where a structure is being passed by value. I need to add the `byval`
attribute somewhere (I'm not clear if this is on the function arguments
or the type).
I'm also uncertain of why that results in a different calling convention
than just:
%1 = call i64 @abi_call_test_tuple_2p(%":abi_tuple_2" %0)
Does this not also pass the same structure by-value to the function?
(It doesn't yield the same results it appears).
