[Bug c/14924] New: Compiler ICE on valid code

["edmar at motorola dot com" <gcc-bugzilla at gcc dot gnu dot org>]

There is a problem with NE rtl handling for powerpc e500 target on the latest
3.4 pre-release.
This little program, seg faults the compiler:
#include <spe.h>

__ev64_u16__ * g_vp_u16 ;
__ev64_u16__ g_v_u16 ;

void
test___ev_stdd (void)
{
  __ev_stdd (g_v_u16,g_vp_u16,31U);
}

Command line was:
gcc-3.4-20040406/bin/gcc -O1 -S x.c -save-temps

Here is the output:
x.c: In function `test___ev_stdd':
x.c:9: internal compiler error: in copy_to_mode_reg, at explow.c:667
Please submit a full bug report,
with preprocessed source if appropriate.

Several benchmarks in spec2k have problems. Perlbmk also ICE:
op.c: In function `list_assignment':
op.c:2552: error: unrecognizable insn:
(insn:HI 257 256 258 18 (set (reg:CCEQ 212)
       (compare:CCEQ (gtu:SI (reg:CCUNS 211)
               (const_int 0 [0x0]))
           (const_int 0 [0x0]))) -1 (nil)
   (expr_list:REG_DEAD (reg:CCUNS 211)
       (nil)))
op.c:2552: internal compiler error: in extract_insn, at recog.c:2083
