Allow CallSlot optimization for throwing functions for sret arguments
Hi all,
in Rust we have a bug report about about a missed optimization which
one would expect CallSlot optimization to handle:
https://github.com/rust-lang/rust/issues/48533
The IR looks like this:
define void @bar(%S* noalias nocapture sret dereferenceable(16), void
(%S*)* nocapture nonnull) unnamed_addr #0 {
%3 = alloca %S, align 8
%4 = bitcast %S* %3 to i8*
call void
