Trying to bootstrap gcc (4.8-RH, but reproduced also with the trunk) with
a ppc64 compiler configured --with-cpu=power7 ICEs during stage1 while par.adb
is being compiled at -O0.
Reproduced even with a cross-compiler from x86_64-linux, will attach a tarball
with all the required files.

../gnat1 -I. -gnatwa -quiet -nostdinc -m64 -gnatpg -gnatwns -mtune=power7
-mcpu=power7 par.adb -o /tmp/par.s
par.adb: In function ‘Par’:
par.adb:1604:5: error: insn does not satisfy its constraints:
(insn 1505 719 1504 (set (reg:TI 77 0)
        (const_double -16 [0xfffffffffffffff0] 7 [0x7] 0 [0] 0 [0]))
par.adb:1509 721 {*vsx_movti_64bit}
     (nil))

Created attachment 30941

I've tried to create a C small reproducer from scratch, but just using TImode
seems to work, reload decides to put the extra large constant into memory, and
similarly say:
typedef int TI __attribute__((mode (TI)));
void
foo (void)
{
  asm volatile ("" : : "v" (((TI) 0x7fffffffffffffffUL) << 4));
}
