           Summary: Regression @171649: ICE in setup_pressure_classes, at
                    ira.c:877
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
        AssignedTo: unassigned@gcc.gnu.org

Hi!

The large IRA merge (=66d9a7b9e8a0c85a51467330f51ead74e77b7eb8 in GIT) broke
the vax-linux target:

jbglaw@jbarbeitsplatz:/mnt/nfs-programming/toolchain/gcc-build/gcc$ ./xgcc -B .
-c foo.c
foo.c:1:0: internal compiler error: in setup_pressure_classes, at ira.c:877
Please submit a full bug report,
[...]


jbglaw@jbarbeitsplatz:/mnt/nfs-programming/toolchain/gcc-build/gcc$ cat foo.c   
extern int xx (int a, int b);
int
blub (double boo, int oo)           
{
long x;
x = boo * oo;
x += xx (boo, oo);
return x;
}

This is just configured with ../gcc/configure --target=vax-linux
--enable-languages=c --disable-threads on a i686-linux host/build system.
