[Bug tree-optimization/36881] New: [4.4 Regression] Creating runtime relocations for code which does not need it

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Compile gcc.c-torture/execute/20080719-1.c with -O2 -fPIC and you will get:
gcc/gcc/testsuite/gcc.c-torture/execute/20080719-1.c: In function ?xxx?:
gcc/gcc/testsuite/gcc.c-torture/execute/20080719-1.c:65: error: creating
run-time relocation for ?cfb_tab8_be?
gcc/gcc/testsuite/gcc.c-torture/execute/20080719-1.c:65: error: creating
run-time relocation for ?cfb_tab32?
gcc/gcc/testsuite/gcc.c-torture/execute/20080719-1.c:65: error: creating
run-time relocation for ?cfb_tab32?

This is because of the switch conversion pass which should be disabled for
-fPIC on spu-elf.  The runtime loader for spu does not currently support
runtime relocations.

If we compile with -O1 -fPIC, these runtime relocations are not created.
