There are similar tests on ARM only. When I tried to extend them I've got the following:

  ldrb r12, [lr, r12]!
  ldrb lr, [lr, #1]

Instead of 1 ldrh.

I'm not sure what is more profitable for ARM and which -mtriple/-mcpu is better. So I'd better leave the test inserting for ARM guys.


Repository:
  rL LLVM
