           Summary: ffitest failures on Solaris 8/SPARC
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: ro at techfak dot uni-bielefeld dot de
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: sparc-sun-solaris2.8
  GCC host triplet: sparc-sun-solaris2.8
GCC target triplet: sparc-sun-solaris2.8

The libffi test ffitest fails for both 32-bit and 64-bit (sparcv9):

in sparc-sun-solaris2.8/libffi, run

LD_LIBRARY_PATH=../../gcc ./ffitest

The test ends with

Enter FFI_CLOSURES

Bus Error

In gdb, you find

Program received signal SIGSEGV, Segmentation fault.
0x00011364 in closure_test_fn1 (cif=0xffbee864, resp=0xffbee7f8, 
    args=0xffbee748, userdata=0x3)
    at /vol/gnu/src/gcc/gcc-dist/libffi/src/ffitest.c:325
1: x/i $pc  0x11364 <closure_test_fn1+156>:	ldd  [ %i0 ], %f8

%i0 (= cif) is not properly aligned for an 8-byte value, as can be observed
using truss:

9025:       Incurred fault #5, FLTACCESS  %pc = 0x00011364
9025:         siginfo: SIGBUS BUS_ADRALN addr=0xFFBEE8EC

9025:         siginfo: SIGBUS BUS_ADRALN addr=0xFFBEE8EC
9025:           *** process killed ***

The SPARC-V9 test also fails, though in a different way:

in sparc-sun-solaris2.8/sparcv9/libffi, run

LD_LIBRARY_PATH=../../../gcc/sparcv9 ./ffitest

The test ends with

Enter FFI_CLOSURES

If you disable the exit(EXIT_FAILURE) in ffitest.c (fail), the test finds
yet more errors:
