xbolva00 added a comment.
This really needs to be properly benchmarked.
================
Comment at: llvm/test/Transforms/InstCombine/AMDGPU/memcpy-from-constant.ll:9
; Simple memcpy to alloca from constant address space argument.
define i8 @memcpy_constant_arg_ptr_to_alloca([32 x i8] addrspace(4)* noalias
readonly align 4 dereferenceable(32) %arg, i32 %idx) {
----------------
No longer happens..
================
Comment at: llvm/test/Transforms/LICM/hoist-deref-load.ll:419
; and we want to hoist the load of %c out of the loop. This can be done only
; because the dereferenceable meatdata on the c = *cptr load.
define void @test7(i32* noalias %a, i32* %b, i32** %cptr, i32 %n) #0 {
----------------
Regression in that C code?
