ARM: yet another round of ARM test clean ups llvm-svn: 205586

Convert Thumb2 tests to FileCheck for PR5307. llvm-svn: 89595
2009-11-22 23:18:27 +08:00
Remove -join-physregs from the test suite. This option has been disabled for a while, and it is going away so I can clean up the coalescer code. The tests that required physreg joining to be enabled were almost all of the form "tiny function with interference between arguments and return value". Such functions are usually inlined in the real world. The problem exposed by phys_subreg_coalesce-3.ll is real, but fairly rare. llvm-svn: 157027

; These tests would be improved by 'movs r0, #0' being rematerialized below the
; test as 'mov.w r0, #0'.
