           Summary: scan for mov fails in gcc.target/arm/pr42575.c
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: janis@gcc.gnu.org


Test gcc.target/arm/pr42575.c was added on 2010-08-18 in r163334.  The scan for
no "mov" started failing a few days later with:

  r163601 | bernds | 2010-08-27 22:11:50 +0000 (Fri, 27 Aug 2010)

The test specifies -march=armv7-a, which is overridden for multilibs that
specify -march=, but it fails even for the default multilib.  It passes for a
few multilibs.  Here are results for the scan for current trunk with the
multilibs I've been using for compile-only tests, in case that provides useful
clues:

  default: FAIL
  march_armv4t: FAIL
  march_armv5: FAIL
  march_armv5te: FAIL
  march_armv5te-mfloat-abi_softfp: FAIL
  march_armv5te-mfloat-abi_softfp-mbig-endian: FAIL
  march_armv5t: FAIL
  march_armv6: FAIL
  march_armv6j: FAIL
  march_armv6t2: PASS
  march_armv6z: PASS
  march_armv6zk: PASS
  march_armv7-a: FAIL
  march_armv7-a-mfloat-abi_hard-mfpu_neon: FAIL
  march_armv7-a-mfloat-abi_softfp-mfpu_neon: FAIL
  march_armv7-r: FAIL
  march_iwmmxt2: FAIL
  march_iwmmxt: FAIL
  mbig-endian: FAIL
  mcpu_xscale: PASS
  mfloat-abi_soft-mfpu_neon-fp16: FAIL
  mfloat-abi_soft-mfpu_vfpv3xd-fp16: FAIL
  mfpu_vfpv4: FAIL
  mthumb: PASS
  mthumb-march_armv4t: PASS
  mthumb-march_armv5te: PASS
  mthumb-march_armv5t: PASS
  mthumb-march_armv6: PASS
  mthumb-march_armv6j: PASS
  mthumb-march_armv6-m: PASS
  mthumb-march_armv6t2: PASS
  mthumb-march_armv6z: PASS
  mthumb-march_armv6zk: PASS
  mthumb-march_armv7-a: PASS
  mthumb-march_armv7: PASS
  mthumb-march_armv7-mfix-cortex-m3-ldrd: PASS
  mthumb-march_armv7-m: PASS
  mthumb-march_armv7-r: FAIL
  mthumb-march_iwmmxt2: PASS
  mthumb-march_iwmmxt: PASS
  mthumb-mcpu_cortex-a8: PASS

With the 4.6 branch the only difference is that mcpu_xscale fails.
