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.

Modified: branches/gcc-4_4-branch/gcc/ChangeLog branches/gcc-4_4-branch/gcc/config/arm/arm.h
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.
