+;This file contains auto generated tests for the lowering of passing structs
+;byval in the arm backend. We have tests for both packed and unpacked
+;structs at varying alignments. Each test is run for arm, thumb2 and thumb1.
+;We check for the strings in the generated object code using llvm-objdump
+;because it provides better assurance that we are generating instructions
+;for the correct architecture. Otherwise we could accidently generate an
+;ARM instruction for THUMB1 and wouldn't detect it because the assembly
+;code representation is the same, but the object code would be generated
+;incorrectly. For each test we check for the label, a load instruction of the
+;correct form, a branch if it will be generated with a loop, and the leftover
+;cleanup if the number of bytes does not divide evenly by the store size
