----------------
Does it mean we are able to pass blockaddress out of current function? For that
case, we can't put it in the indirect labels list, right?
================
Comment at: llvm/test/tools/llvm-diff/callbr.ll:28-29
entry:
- callbr void asm sideeffect "", "X,X,~{dirflag},~{fpsr},~{flags}"(i8*
blockaddress(@foo, %t_no), i8* blockaddress(@foo, %return))
+ callbr void asm sideeffect "", "i,i,~{dirflag},~{fpsr},~{flags}"(i8*
blockaddress(@foo, %t_no), i8* blockaddress(@foo, %return))
to label %asm.fallthrough [label %return, label %t_no]
----------------
If my above assumption is true, I think we can't replace the `X` with `i` here.
Besides, I'm confused on the indirect labels list. Are they the labels of `bar`
or `foo`?
