[PATCH] D12946: Avoid pointer truncation by InstCombine with IntToPtr combining

[Matt Arsenault via llvm-commits]

arsenm added a comment.

I think for our purposes we care more about the address space of alloca being distinct from the address space of code.

I think adding support for non-0 addrspace alloca would mostly solve this problem and a few other related ones around address space 0 assumptions. The "default" address space code pointer would then just happen to work.
