In the test-case to be attached and entered in gcc.c-torture/execute
alt. gcc.dg/torture as prNNNNN-1.c, there's a call to get_n, which
is moved out of the loop. This happens before rtl passes.
The FC3-bundled gcc known as gcc-3.4.2-6.fc3 (for i686) does not
have this bug. Trunk as of LAST_UPDATED "Sat Feb 19 00:34:51 UTC 2005"
has this bug, apparent with cris-axis-elf and i686-pc-linux-gnu.
