commit 65971d4e677e74d9b2d64677bb62001ca204cb5e

    ipa-sra is mostly disabled by -mlongcall - work around it
    
    Several ipa-sra tests fail because -mlongcall on powerpc is a
    TYPE_ATTRIBUTE, and those disable ipa-sra.
    
    This local workaround disables -mlongcall for the failing tests on
    powerpc*-*-vxworks*, so they get a chance to run even in kernel mode.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.dg/ipa/ipa-sra-12.c: Add -mno-longcall on ppc*-vxworks*.
            * gcc.dg/ipa/ipa-sra-13.c: Likewise.
            * gcc.dg/ipa/ipa-sra-15.c: Likewise.
            * gcc.dg/ipa/ipa-sra-16.c: Likewise.
            * gcc.dg/ipa/ipa-sra-17.c: Likewise.
            * gcc.dg/ipa/ipa-sra-18.c: Likewise.
