[Bug testsuite/39781] New: Fail: g++.dg/cpp/_Pragma1.C, gcc.dg/cpp/_Pragma6.c

[jingyu at google dot com]

These two tests require that platform supports pragma pack(push).

For example, gcc.dg/cpp_Pragma6.c:
/* PR c/27747 */
/* This is supposed to succeed only if
   the target defines HANDLE_PRAGMA_PACK_PUSH_POP
   and doesn't define HANDLE_PRAGMA_PACK_WITH_EXPANSION.  */
/* { dg-do compile { target { ! { powerpc-ibm-aix* *-*-solaris2* fido-*-*
m68k-*-* sh*-[us]*-elf m32c-*-* } } } } */

#define push bar
#define foo _Pragma ("pack(push)")
foo
int i;
#pragma pack(pop)

However, config/arm does not define "HANDLE_PRAGMA_PACK_PUSH_POP". So GCC gives
the following warning which breaks the dejaGNU test.
  "warning: #pragma pack(push[, id], ) is not supported on this target"

The same failure is also observed on the report:
http://gcc.gnu.org/ml/gcc-testresults/2009-04/msg01473.html

Suggest to filter arm-*-* out of the test target list.

$arm-eabi-gcc -v

Add HANDLE_PRAGMA_PACK_PUSH_POP to arm.
Tests are done for both gcc trunk and gcc-4.4.
These two failures become pass.
Patch was submitted to trunk and gcc-4.4.
