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
Using built-in specs.
