gcc/testsuite/ChangeLog: * gcc.target/i386/large-size-array-3.c: New.

Index: testsuite/gcc.target/i386/large-size-array-3.c

--- testsuite/gcc.target/i386/large-size-array-3.c (revision 0) +++ testsuite/gcc.target/i386/large-size-array-3.c (revision 0) @@ -0,0 +1,4 @@ +/* { dg-do compile { target i?86-- x86_64-- } } / +/ { dg-options "-m64" } / +/ { dg-final { scan-assembler "8589934592" } } */ +int bigarray[2147483647];

This testcase will not work on the plain target i686-linux-gnu as 64bit compiling is not included by default. The dg-do command should instead be something like: /* { dg-do compile { target { { i?86-- x86_64-- } && lp64 } } } */
