>Description:
I get extra failures w/-m64 when RTL checking is turned on:

FAIL: gcc.c-torture/compile/960704-1.c,  -O1
FAIL: gcc.c-torture/compile/960704-1.c,  -O2
FAIL: gcc.c-torture/compile/960704-1.c,  -O3 -fomit-frame-pointer
FAIL: gcc.c-torture/compile/960704-1.c,  -O3 -g
FAIL: gcc.c-torture/compile/960704-1.c,  -Os

FAIL: gcc.c-torture/execute/991019-1.c compilation,  -O1
FAIL: gcc.c-torture/execute/991019-1.c compilation,  -O2
FAIL: gcc.c-torture/execute/991019-1.c compilation,  -Os

The failures look like this:

compile/960704-1.c:9: internal compiler error: RTL check: expected code `const_double', have `const_int' in compress_float_constant, at expr.c:3428

execute/991019-1.c:22: internal compiler error: RTL check: expected code `const_double', have `const_int' in compress_float_constant, at expr.c:3428

This is a regression from gcc-3.2
