<pre>Thanks, Zvi! This is now optimized differently in IR:
define i32 @foo(i32 %x) local_unnamed_addr #0 {
entry:
%cmp = icmp eq i32 %x, 1
%.sink = select i1 %cmp, i32 1, i32 -1
%call1 = tail call i32 @bar(i32 %.sink) #2
ret i32 %call1
}
declare i32 @bar(i32) local_unnamed_addr #1
-------------------------------------------------------------------------
This is likely due to one of James Molloy's (cc'ing) improvements to
SimplifyCFG. <a href="https://reviews.llvm.org/D22143">https://reviews.llvm.org/D22143</a> ?
Resolving as fixed.</pre>
