================
Comment at: test/CodeGen/X86/slow-div.ll:29-43
 ; Verify that no extra code is generated when optimizing for size.
 
 define i32 @div32_optsize(i32 %a, i32 %b) optsize {
 ; DIV32-LABEL: div32_optsize:
 ; DIV32-NOT: divb
   %div = sdiv i32 %a, %b
   ret i32 %div

Such a test is added in D28551 (see bypass-slow-division-tune.ll file)
