[Bug target/41176] New: ICE in reload_cse_simplify_operands at postreload.c:396

[lucier at math dot purdue dot edu]

with this compiler:

[lucier@lambda-head lib]$ /pkgs/gcc-mainline/bin/gcc -v
Using built-in specs.
Target: powerpc64-unknown-linux-gnu
Configured with: ../../mainline/configure --prefix=/pkgs/gcc-mainline
--enable-languages=c,c++ --enable-stage1-languages=c,c++ --with-cpu=default64
Thread model: posix
gcc version 4.5.0 20090825 (experimental) [trunk revision 151108] (GCC) 

and this command line

 /pkgs/gcc-mainline/libexec/gcc/powerpc64-unknown-linux-gnu/4.5.0/cc1
-fpreprocessed thread.i -quiet -mcpu=970 -m64  -O1 -Wno-unused -version
-fschedule-insns -fno-math-errno -fschedule-insns2 -fno-trapping-math
-fno-strict-aliasing -fwrapv -fomit-frame-pointer -fPIC -fno-common

I get the following error:

thread.i: In function ‘___H_make_2d_thread’:
thread.i:719:1: error: insn does not satisfy its constraints:
(insn 625 411 219 26 thread.i:625 (set (reg:DF 19 19)
        (mem:DF (plus:DI (reg:DI 22 22 [orig:197 D.3836 ] [197])
                (const_int 23 [0x17])) [0 S8 A64])) 357 {*movdf_hardfloat64}
(nil))
thread.i:719:1: internal compiler error: in reload_cse_simplify_operands, at
postreload.c:396

I apologize in advance for the size of the test case, which I will post next.
